Genesis 21:1-34

Genesis chapter 21. It's a long 
chapter, there's a lot going on, so I'll go ahead and start 
reading in verse 1 of Genesis chapter 21. And the Lord visited 
Sarah as he had said, and the Lord did for Sarah as he had 
spoken. For Sarah conceived and bore 
Abraham a son in his old age, at the set time of which God 
had spoken to him. And Abraham called the name of 
his son who was born to him, whom Sarah bore to him, Isaac. Then Abraham circumcised his 
son Isaac when he was eight days old, as God had commanded him. 
Now Abraham was 100 years old when his son Isaac was born to 
him. And Sarah said, God has made me laugh, and all who hear 
will laugh with me. She also said, who would have 
said to Abraham that Sarah would nurse children? For I have born 
him a son in his old age. So the child grew and was weaned, 
and Abraham made a great feast on the same day that Isaac was 
weaned. And Sarah saw the son of Hagar, the Egyptian, whom 
she had borne to Abraham, scoffing. Therefore she said to Abraham, 
Cast out this bondwoman and her son, for the son of this bondwoman 
shall not be heir with my son, namely with Isaac. And the matter 
was very displeasing in Abraham's sight because of his son. But 
God said to Abraham, Do not let it be displeasing in your sight 
because of the latter, because of your bondwoman. Whatever Sarah 
has said to you, listen to her voice, for in Isaac your seed 
shall be called. Yet I will also make a nation 
of the son of the bondwoman, because he is your seed." So 
Abraham rose early in the morning and took bread and a skin of 
water, and putting it on her shoulder, he gave it and the 
boy to Hagar and sent her away. Then she departed and wandered 
in the wilderness of Beersheba, and the water in the skin was 
used up, and she placed the boy under one of the shrubs. Then 
she went and sat down across from him at a distance of about 
a bowshot, for she said to herself, let me not see the death of the 
boy. So she sat opposite him and lifted her voice and wept. 
And God heard the voice of the lad. Then the angel of God called 
to Hagar out of heaven and said to her, What ails you, Hagar? 
Fear not, for God has heard the voice of the lad where he is. 
Arise, lift up the lad, and hold him with your hand, for I will 
make him a great nation. Then God opened her eyes, and 
she saw a well of water. And she went and filled the skin 
with water and gave the lad a drink. So God was with the lad, and 
he grew and dwelt in the wilderness and became an archer. He dwelt 
in the wilderness of Perun, and his mother took a wife for him 
from the land of Egypt. And it came to pass at the time 
that Abimelech in Phicol, the commander of his army, spoke 
to Abraham, saying, God is with you in all that you do. Now, 
therefore, swear to me by God that you will not deal falsely 
with me, with my offspring, or with my posterity, but that according 
to the kindness that I have done to you, you will do to me and 
to the land in which you have dwelt. And Abraham said, I will 
swear. Then Abraham rebuked Abimelech 
because of a well of water which Abimelech's servants had seized. 
And Abimelech said, I do not know who has done this thing. 
You did not tell me, nor had I heard of it until today. So 
Abraham took sheep and oxen and gave them to Abimelech, and the 
two of them made a covenant. And Abraham set seven new lambs 
of the flock by themselves. Then Abimelech asked Abraham, 
what is the meaning of these seven new lambs which you have 
set by themselves? And he said, you will take these 
seven new lambs from my hand, that they may be my witness that 
I have dug this well. Therefore he called that place 
Beersheba, because the two of them swore an oath there. Thus 
they made a covenant at Beersheba. So Abimelech arose with Phicol, 
the commander of his army, and they returned to the land of 
the Philistines. Then Abraham planted a tamarisk tree in Beersheba, 
and there called on the name of the Lord, the everlasting 
God. And Abraham stayed in the land of the Philistines many 
days. Well, this chapter certainly has, as I said, a lot going on. 
The first section deals with the birth of Isaac, the second 
with the expulsion of or the banishment of Ishmael, and then 
finally this covenant with Abimelech in verses 22 to 34. So we see 
God's promises concerning a son to Abraham and Sarah come to 
fruition here specifically in verses 1 to 7. We see it maintained 
that Isaac would in fact be the son of promise. Therefore Ishmael 
is expelled, Ishmael is sent away, and then Abraham makes 
this covenant with Abimelech. And I think that what is going 
on in this particular chapter is the fulfillment of God's promises. 
There was first a promise concerning seed, which we have with reference 
to Isaac, and there is a promise with reference to land, which 
we have with this well. that Abraham gains. It's a well that belongs specifically 
to him in the land of promise. Now remember, God promised Abraham 
the entirety of Canaan. But at this particular juncture, 
they didn't have a right to take Canaan. And so Abraham, in many 
respects, is a stranger in a strange land. But by bits and pieces, 
God is realizing or fulfilling that promise to Abraham such 
that he is, in fact, receiving the land. So seed in the first 
part and then land in the latter part shows the faithfulness of 
God in terms of his promises to Abraham made when Abraham 
was called out of Ur of the Chaldeans. He went to Haran and then ultimately 
entered into Canaan according to Genesis chapter 12. So let's 
look first of all at the birth of Isaac in verses 1 to 7. We note in the first place the 
fulfillment of God's promise, and note how this is emphasized 
in verses 1 and 2. The Lord visited Sarah as he 
had said, and the Lord did for Sarah as he had spoken. For Sarah conceived and bore 
Abraham a son in his old age, at the time of which God had 
spoken to him. So again, there's a general promise 
concerning descendants for Abraham in Genesis chapter 12. There's 
a general promise concerning descendants for Abraham in Genesis 
chapter 13. There is a specific promise in 
Genesis 15 that there would be a seed born of Abraham and Sarah. And then the specific promise 
of Isaac as that son is given by God to Abraham in chapter 
17 at verse 19, and then given to Sarah in chapter 18 at verses 
10 to 12. So we see that God fulfilled 
the promise. Now remember, this is about a 
25-year period. When Abraham comes out of Haran, 
when he enters into the promised land, this is when God gives 
him the initial promise that he would have descendants. Well, 
25 years has passed. He certainly has a descendant 
in Ishmael, but as God has reiterated over and over and over again, 
to Abraham it's not going to be Ishmael. Rather, it's going 
to be a natural-born son from you and from Sarah. And so in 
this, we not only see the faithfulness of God Almighty, but we see the 
persevering faith of Abraham. It's tough to live in light of 
a promise for 25 years. We are an impatient people, and 
we want our answers right away. Well, we need to learn with reference 
to Scripture that we need to be patient. Trusting what the 
Lord has said, He will in fact deliver in His good timing. Notice 
in verse 2, the reference again to Abraham's old age. This is 
the perennial problem that has faced this couple all along the 
way. They're both too old for them 
to have a child. And so in verse 2, Sarah conceived 
and bore Abraham a son in his old age. Calvin says, concerning 
Moses who wrote the narrative, he says, for he thus retains 
his readers as by laying his hand upon them that they may 
pause in the consideration of so great a miracle. Meanwhile, 
Moses commends the faithfulness of God as if he had said he never 
feeds men with empty promises. Nor is He less true in granting 
what He has promised than He is liberal and willing in making 
the promise. So God doesn't disappoint. God does not frustrate His people. 
When God gives a promise, even if it takes 25 years or in some 
instances 430 years, the Lord God always is good on His promises. Now, in terms of the birth of 
Isaac in verses 2 to 7, you have two different divisions. On the 
one hand, you have sort of the ordinary details, and then on 
the other hand, you have the extraordinary details. The first 
ordinary detail is the birth of a son. Verse 2, Abraham and 
Sarah give birth to a son. Again, the reality that they're 
that old is still something we ought to marvel at. As well, 
he names the son, Isaac, in verse 3, according to what God told 
him in chapter 17, verse 19. Remember the name Isaac means 
laughter. Both Abraham and Sarah laughed 
when they were told by God that they were going to have this 
baby. In Genesis 17, Abraham laughs. Genesis 18, Sarah laughs. Here later, we have Ishmael. 
Same verb, only it does have that larger range where he scoffs. The verb is, he laughed, but 
it has that meaning of scoffing, or it was derisive when he saw 
what was going on at the weaning ceremony of Isaac. So the son 
is named, and then the son is circumcised. Notice in verse 
4, then Abraham circumcised his son Isaac when he was eight days 
old, as God had commanded him. Again, you see the religious 
obedience of Abraham to the command of God. He doesn't play around. 
He does what God commanded. Named the son Isaac, circumcised 
the son on the eighth day, that in accordance with that covenant 
of circumcision in Genesis 17 at verse 12. Now, in terms of 
the extraordinary details, verses 5 to 7. Notice the old age of 
Abraham and Sarah, verse 5. Now, Abraham was 100 years old 
when his son Isaac was born to him. It's very obvious and very 
specific and very conspicuous that the author wants us to remember 
this. He wants us to understand the 
great difficulty involved in this and that this is, in fact, 
an extraordinary birth. It's not the case that this was 
run of the mill. And then in verse 6, we see the 
reference to her laughter and the laughter of others. Sarah 
said, God has made me laugh, and all who hear will laugh with 
me. I take it as the... one's laughing, it will be in 
joy. It will be the response of happiness 
at the reality that this woman, Sarah, has given birth to a son 
for Abraham. And then in verse 7, she also 
said, Who would have said to Abraham that Sarah would nurse 
children? For I have borne him a son in 
his old age. We do that sort of thing from 
time to time as well. Who would have thought it would have ever 
turned out this way? It's truly amazing. It's an incredible 
thing. And that's precisely what Sarah 
is doing. At the birth of this son, Isaac, 
she is musing on the natural order with reference to her age 
and with reference to Abraham's age. And now she is giving sock 
to a baby on her breast. And she says, who in the world 
would have ever thought that such a thing like this would 
have ever happened? And that is accurate. She understands 
the miraculous power of the living and true God with reference to 
the birth of Isaac, the son of promise. Now note the expulsion 
of Ishmael. This is a rough passage of Scripture. As we go back to chapter 16, 
we see the incident where Abraham goes into Hagar and they have 
Ishmael. It's at the bidding of Sarah. Sarah then turns against Hagar, 
God comes to comfort Hagar, and God gives promises to Hagar concerning 
Ishmael. Well, we see those promises fulfilled 
in this particular chapter and amplified or explained as to 
what all is going to be involved in the life of this Ishmael. 
Though he's not the son of promise, God doesn't forget him. Though 
he is not the one from whom Messiah is going to come, He is nevertheless 
going to be a great man. He is going to be the leader 
of other nations, and he is going to receive great benefit from 
the living and true God. In fact, the Lord is with Ishmael 
according to this particular chapter. But notice with reference 
to the words of Sarah in verses 8 to 11. We have in the first 
instance the weaning of Isaac. So the child grew and was weaned, 
and Abraham made a great feast on the same day that Isaac was 
weaned, probably about the age of three. That's roughly the 
estimate from the commentators. Others have pushed it to further 
on, you know, six or seven. Others have said around two, 
probably around the age of three. And some would say, why would 
they have a great feast when the child was weaned? Wouldn't 
you have a great feast when the child was born? Well, we don't 
know that they didn't have a great feast when the child was born, 
but in a day and age where infant mortality rates were very high, 
the fact that a child makes it to the age of three is the cause 
of great celebration, especially when this child has come as a 
result of the living and true God. So we cannot begrudge Abraham 
from throwing this great feast, but we see that Ishmael does 
according to verse 9. It says, Sarah saw the son of 
Hagar, the Egyptian, whom she had borne to Abraham, scoffing. He's never mentioned by name. 
Ishmael is not mentioned by name in this section. Sarah refers 
to the bondwoman and her son. Sarah is distancing herself from 
those two, and Sarah wants them gone. That's what we'll see in 
just a moment, but it says that this young man, Ishmael, probably 
about the age of 16 or 17 at this particular time, he's scoffing. or he's laughing. Now, the mocking 
of Isaac by Ishmael, the same word as I said is laughter, but 
here it's not joy at the birth of Isaac, but it is derisive, 
it is scoffing, it is more derision. Perhaps as the firstborn, he's 
looking down upon the secondborn. Perhaps as the firstborn, he's 
thinking that he alone is entitled to the inheritance that will 
come from Abraham. That is certainly Sarah's concern 
as we move through this particular section. And whatever he does 
in terms of this derision, it irritates Sarah to the point 
where she then speaks to Abraham in a way that is quite forward 
and quite demanding. Now, if you look at the book 
of Galatians, in Galatians chapter 4, we won't have a lot of time 
to sort of unpack that, but at the end we'll at least read the 
section. In Galatians 4, 21 to 31, the Apostle Paul appeals 
to this passage. And the Apostle Paul appeals 
to this passage to show the differences between Old Covenant and New 
Covenant, to show the difference between the law and the promise, 
to show the difference between the flesh and the promise. And 
here the Apostle says that this scoffing or this mocking or this 
derision was an act of persecution on the part of Ishmael toward 
Isaac. That's how Paul interprets what's 
happening and applies it to the situation going on with reference 
to these Judaizers coming to the church, parading the whole 
idea of law for salvation and parading the whole idea of flesh 
for salvation. Paul says they've missed the 
point by a long shot. Abraham had two sons. One son 
was a son of promise, that was Isaac, and the other son was 
a son according to the flesh, that was Ishmael. So Paul deals 
with this particular section in Galatians 4, 21 to 31. He 
calls it an allegory, and it is there as a means by which 
he shows covenant theology. So as we read through this, we 
ought to think of Hagar and Sarah as being sort of not covenantal 
heads, but at least representatives in an allegorical fashion of 
God's covenantal dealings with his people. Now note the words 
of Sarah in verse 10. Therefore she said to Abraham, 
cast out this bondwoman and her son, for the son of this bondwoman 
shall not be heir with my son, namely with Isaac. Now again, 
what does Peter tell us concerning Sarah? She called Abraham Lord. She was submissive to her husband. 
As we read through these narratives, there's not one whiff of Sarah 
ever speaking like this to Abraham. Well, in this instance, she does. 
She says, cast out this bondwoman and her son, for the son of this 
bondwoman shall not be heir with my son, not with Isaac. So her 
concern isn't here motivated by her own selfishness or by 
her own greed, but rather it is with reference to this son 
of promise, namely Isaac. Now how does Abraham respond 
to that? It's intriguing because if you look at verse 11, typically 
when the Bible indicates that somebody's unhappy, or when the 
Bible indicates that God is unhappy, again after the manner of men, 
it uses the language of displeased. This case, Abraham was very displeased 
in this. This was a great blow to Abraham. Now remember, Abraham loved Ishmael. Abraham loved this boy, and he 
had been with this boy for the 16 or the 17 years that this 
boy had been alive. So in verse 11, the matter was 
very displeasing in Abraham's sight because of his son. John Gill explains, he says, 
his chief concern was for his son. Doesn't mention anything 
about Hagar. His chief concern was for his 
son, but as we move through it, he is concerned for her as well. 
But his chief concern was for his son, who perhaps had a greater 
share in his natural affections than as yet Isaac had. So Isaac's 
three and Ishmael is 16 or 17. He's known him longer. He's closer 
to him. I don't think that's outlandish. He goes on to say, 
nor did he express so much reluctance when he was bid to offer Isaac 
up. When we get to chapter 22 and 
God tells Abraham to go off for Isaac, he isn't very displeased 
at that. He doesn't have a... I mean, 
I'm sure it's a psychological turmoil and a great deal of pressure 
and a great deal of stress, but he doesn't express that he's 
very displeased at this particular situation. So back to Gil. So nor did he express so much 
reluctance when he was bid to offer him up as he did at this 
time, that, the offering up of Isaac, being at the command of 
God. This, at the instance of his 
wife, and which he supposed only proceeded from passion and resentment. So he's very displeased at this 
particular point because he thinks this is a jealous, a resentful, 
a perhaps bitter Sarah that is saying, cast out the bondwoman 
and her son. get him out of my sight. Now 
that Isaac is here, I want no truck with those people whatsoever. 
And then Gil says, the Hebrew writers say that of all the evils 
that came upon Abraham, this was the hardest and most grievous 
in his sight. Now, whether that's the case 
or not, you can at least enter in to see It had to be tough 
for Father Abraham. He had great natural affection 
for his son Ishmael, and now his wife Sarah says, cast out 
the bondwoman and her son. There's no way he's going to 
be an heir with my son, namely Isaac. Now note God's endorsement 
of Sarah's language in verses 12 and 13. But God said to Abraham, 
do not let it be displeasing in your sight because of the 
lad or because of your bondwoman. It's very intriguing, the nouns 
that are used to describe Ishmael. Lad is the appropriate terminology 
you use for a youngish man, 16, 17, like that. But then when 
we get to that passage, when Abraham sends him off and when 
he's with Hagar there in Beersheba and he has to take sort of refuge 
under that shrub and he's about to die, he's the boy. I think 
that the author is showing us the vulnerability of the boy 
in that particular instance. There's really, you know, great 
storytelling and artwork in terms of literary going on in this 
particular section. But here God says that Sarah's 
right. Do not let it be displeasing 
in your sight because of the latter, because of your bondwoman. 
Whatever Sarah has said to you, listen to her voice, for in Isaac 
your seed shall be called." See, it's according to the sovereignty 
of God. See, this is why I think at times people get pretty upset 
about God's sovereignty, because they don't like the implications. 
They say things like, well, that's not fair. I mean, here you have 
Ishmael, and he was a good lad, and he had never done anything 
evil or wicked or horrible. We don't really know what he 
did, but Abraham loved him, and it was his son, and all that 
sort of thing. It just doesn't seem fair that now he's banished, 
now he's exiled, now he's expelled, and he's out. That's the sovereignty 
of God. That is according to his prerogative, 
and his purposes, and his plans. With reference to Jacob and Esau, 
before the sons or twins were born, God had already made that 
distinction. This is what God's sovereignty 
is all about. Not unfairness, but the execution 
of His sovereign will according to His purpose for His glory 
and the good of His elect by and through Jesus Christ. Isaac 
is the son of promise. In Isaac your seed shall be called. 
That's the emphasis. The Lord God Most High is preaching 
Jesus right now to Abraham. He's preaching Jesus right now 
to those involved in this particular situation. The seed of Abraham 
is absolutely crucial and it isn't in Ishmael. Now having 
said that, notice what verse 13 says. Yet I will also make 
a nation of the son of the bondwoman, because he is your seed. So he 
doesn't just cut him off once and for all. Ishmael does go 
on to be a great man in his own right. Not an elect man, not 
a spiritual man, not a saved man in terms of God's redemptive 
plan through Jesus Christ, but nevertheless a great man. Now 
notice the expulsion of Ishmael in verses 14 to 21. Again, this 
is a tough section. As we march with Abraham here 
and as we march with Abraham in Genesis chapter 22, it hopefully 
puts our trials and our issues and our difficulties in some 
degree of perspective. I mean, are we called by God 
to exile a son that we love, one that we've had for 16 or 
17 years, that we've grown quite fond of? Are we called by God 
to take the son of our love, the one who came from our beloved 
wife? Are we ever called by God to 
take him up to Mount Moriah and to kill him? If you ever think 
you've got lots of problems in your life, it might not be a 
bad idea to read Genesis 21 and 22 and say, what did Father Abraham 
have to go through? What kinds of things did he have 
to do in terms of perseverance with reference to his Christianity? 
It certainly cost Abraham a lot to be a disciple of the living 
and true God, and here we see that in verse 14. Notice what 
it says. So Abraham rose early in the 
morning. Compare that with verse 3 in chapter 22. So Abraham rose 
early in the morning. On two instances, he has to rise 
early in the morning because he's got to go about some very 
difficult business with the people that he loves more than anything 
else in the world. So in verse 14, Abraham rose 
early in the morning and took bread and a skin of water and 
putting it on her shoulder, he gave it and the boy to Hagar 
and sent her away. Now the grammar is such that 
some have conveyed it or construed it this way. that he put the 
water, and he put the bread, and he put Ishmael on her shoulders. I think the new King James represents 
it better. Now, for those who look perplexed, 
the grammar or the syntax can go that way. And some have thought 
that she was actually carrying Ishmael on her shoulders on this 
particular journey. But again, he's 16 or 17. That 
just does not seem like the accurate sort of translation of this passage. But what is intriguing is the 
littleness of the provision that he provides for them. A loaf 
of bread and a skin of water. That's not a lot of vittles for 
the journey that they would need to make. Why is it that Abraham 
only gives them so little? The skin of water was probably 
about 15 liters or three gallons. Gallons are better than liters. That's just an Americanism. In 
terms of the why, it is a perplexing thing, isn't it? Here's your, 
you know, Hagar and here's your son Ishmael and they've got a 
journey to make and you give them, you know, 15 liters of 
water and you give them some bread. And, you know, off they 
go. Calvin said, truly, either God shut his eyes that what he 
would gladly have done might not come into his mind, or probably 
better, he says, or Abraham limited her provision in order that she 
might not go far from his house. You got enough bread and water 
to get that far. That's OK. I can come see Ishmael 
when he's that far. I think there's some validity 
to that particular idea. Wenham makes an interesting observation. If you look back at verse 14, 
notice the progression. He rises early in the morning. 
He takes the bread. He takes the skin of water. And 
putting it on his shoulder, he gave it and the boy to Hagar. 
Ishmael's last. He's the last thing he wants 
to part with. He's the last thing he wants to get rid of. Here's 
the water. Here's the bread. Okay, now it's on your shoulder. 
Okay, now I'll give you the boy. Wenham makes this observation. 
One may interpret the sparse provisioning as evoking Abraham's 
numbness at sending his son away rather than lack of concern or 
forethought. In other words, he's so numb 
and paralyzed by the actual activity of sending off his boy, he's 
not thinking in terms, okay, you're gonna be on the road for 
this many days, you're gonna need this much provision, you're 
gonna find a... He doesn't think like that. It's interesting, 
like, you know, the book of Lamentations, the first four chapters are acrostic, 
and they all follow the Hebrew alphabet. They're all 22 verses 
long, except for one of them, chapter three, I think, is 66 
verses. So you have, you know, A-A-A, 
B-B-B, C-C-C. And then the last chapter, no 
acrostic, no artistry, no nothing. And some have suggested that's 
similar to what happens when persons go through grief or loss 
or trial or hardship. They try to keep it together. 
They try to do everything in a routine manner. They try to 
maintain their structure. And then after all is said and 
done, they just lose it and fall apart. Well, maybe Abraham's 
losing it and falling apart in terms of the provision and the 
planning with reference to keeping them alive. He's numb at the 
prospect of having to send his son away. So perhaps that's the 
way we ought to understand the sparseness in terms of the provision. Now, notice in verses 15 and 
16. It doesn't take long. The water is used up, according 
to verse 15. The water in the skin was used 
up, and she placed the boy under one of the shrubs. Then she went 
and sat down across from him at a distance of about a bow 
shot, for she said to herself, let me not see the death of the 
boy. So she sat opposite him and lifted her voice and wept." 
Brethren, that is heartbreaking material. That is very tough 
stuff. Here she is at the end of her 
tether, the water's gone, she puts him in the shrub so that 
he can get the bit of shade that is available there. She goes 
a bow shot away so she doesn't have to see the grief of her 
own boy die. Now, praise God Almighty that 
God is God Almighty because He intervenes in verses 17 to 21. Notice, God heard the voice of 
the lad. We're told that she's crying. 
We're told that she's crying out. Obviously, Ishmael is crying 
as well. The water will eventually provoke 
that or evoke that from you. So God heard the voice of the 
lad. Then the angel of God called the Hagar out of heaven and said 
to her, What ails you, Hagar? Fear not, for God has heard the 
voice of the lad where he is. Go back to chapter 16 for just 
a moment. Chapter 16. Hagar had learned 
this and Hagar is relearning this. Chapter 16 at verse 13. Then she called the name of the 
Lord who spoke to her, you are the God who sees. For she said, 
have I also here seen him who sees me? Therefore, the well 
was called Ber-lehi-roi. Observe it is between Kedesh 
and Bereth. So you have this instance where 
she confesses the ability of God to see, the omniscience of 
God Most High, and now that omniscient God comes to her. Fear not, for 
God has heard the voice of the lad where he is. Verse 18, Arise, 
lift up the lad, and hold him with your hand, for I will make 
him a great nation. So again, here God comes with 
a promise. He's already mentioned it to 
Abraham specifically, now he's mentioning it to Hagar, and he 
is telling her, I am going to make him a great nation. And then we have this blessed 
sort of fulfillment in verses 19 and following. Notice, God 
opened her eyes and she saw a well of water. Some have taught that 
God opened up a well right there. No, it's probably the well was 
there, and he opened her eyes so that she was able to observe 
what was already there. Not that God couldn't have made 
a well, to be sure, but the text is pretty emphatic that He opened 
her eyes and she saw a well of water. She went and filled the 
skin with water and gave the lad a drink. So God resolves 
their immediate issue, their immediate problem. And then verses 
20 and 21 sort of telescope the life of Ishmael. In other words, 
this revisits what God had already spoken, at least in some degree, 
in chapter 16. And it tells us what the disposition 
of this Ishmael is going to be. Not that he's never mentioned 
again in the Bible. He'll be mentioning it in chapter 25, 
13 to 16, when it tells us the sons of Ishmael and then records 
for us the death of Ishmael. But notice in verse 20, God was 
with the lad. God was with the lad. I mean, 
that is an incredible statement. He's not the son of promise. 
He's not the one through whom the Messiah is going to come. 
But nevertheless, God is with him. God made a promise to Abraham, 
and he confirms it to Hagar, and then he fulfills it with 
reference to this man. And he grew and dwelt in the 
wilderness and became an archer. And then notice in verse 21, 
he dwelt in the wilderness of Paran, and his mother took a 
wife for him from the land of Egypt. So it's sort of emphasizing 
that she shouldered the parental responsibilities. It was most 
likely the father's job to find a wife for their son. And so 
the text is telling us that mom stepped in and did everything 
necessary for the maturation of this young man and to promote 
or produce a man that would be married, well-adjusted, as far 
as we know, and having children. That last statement concerning 
the fact that he took a wife paves the way for the reference 
in chapter 25 when we see that Ishmael had children. So it is intriguing. She seeks 
a wife for her boy from her country, from Egypt specifically. So notice 
then, finally, the covenant with Abimelech. This is, again, when 
you first sort of read this chapter, you kind of wonder, is this just 
a tack-on? Is this just sort of an add-on? I mean, I know they're in Gerar. 
This connects, obviously, with chapter 20. Look at verse 22. It says, And it came to pass 
at that time. That time is probably not the 
marriage of Ishmael. That time is probably the birth 
of Isaac. That time when they are living 
in Gerar, they've already dealt with Abimelech to some degree 
according to chapter 20. Remember, they lie to Abimelech 
about their relationship. Abimelech gets, you know, irritated 
to some degree and nevertheless gives them gifts and promises 
them in terms of his land. Whatever you see, you can have 
for yourself. Think about that. Go back to chapter 20 at verse 
15. Chapter 20, verse 14, Abimelech 
took sheep, oxen, and male and female servants and gave them 
to Abraham. And he restored Sarah, his wife, to him. And Abimelech 
said, see, my land is before you. Dwell where it pleases you. So we get to chapter 21. Isaac 
is born. Ishmael is dealt with. And then 
we get back to this situation that obtained between Abraham 
and Abimelech. Now you can understand why Abimelech 
comes to him and says, let's make a treaty together. Let's 
make a covenant together. Because Abimelech had said to 
Abraham, whatever you see in my land, you're free to have. 
But Abimelech's no fool, because he sees how wherever Abraham 
goes, and whatever Abraham does, he prospers. So Abimelech's reading 
the writing on the wall. If this keeps happening, then 
Abraham's going to end up the possessor of Canaan, and I'm 
going to be out of luck. So that's what's driving this 
desire for covenant in verses 22 and 23. Verse 22, it came 
to pass at that time that Abimelech and Phicol, the commander of 
his army, spoke to Abraham saying, God is with you in all that you 
do. You get the sort of motivation here. We want to be on your side. We don't want to be at odds with 
you. We don't want to be contraries. We want to be partners with reference 
to this land that we dwell in. Now, therefore, verse 23, swear 
to me by God that you will not deal falsely with me, with my 
offspring, or with my posterity, but that according to the kindness 
that I have done to you, you will do to me and to the land 
in which you have dwelt. Robert Alter explains it this 
way. He says, now, as Abraham manifestly prospers, Abimelech 
proposes a treaty which will ensure that the Hebrew sojourner 
does not unduly encroach on him or his land. So there's, you 
know, that desire in Abimelech to facilitate things and make 
sure there's good relationship going on. So Abraham says, I 
will swear in verse 24. Now Abraham brings up a particular 
complaint that he has with reference to Abimelech's men. And that's 
verse 25, excuse me. It says, Abraham rebuked Abimelech 
because of a well of water which Abimelech's servants had seized. 
And Abimelech said, I do not know who has done this thing. 
You did not tell me, nor had I heard of it until today. So 
Abimelech, whether he's to be believed or not, Abraham acknowledges, 
I will swear to this covenant. I will enter into this treaty 
with you. I will make sure that I don't run you and your kids 
out of business. Now, ultimately, it's not going 
to be Abraham, but Abraham's descendants. So Abraham can't 
enter into this treaty or covenant with Abimelech in terms of Abimelech's 
posterity, his immediate posterity. When it comes to holy war, obviously 
Abraham's descendants are going to run these people right out 
of the land of Canaan. But for right now, this was a 
treaty and a covenant that certainly Abraham could swear to, so he 
mentions this situation concerning the well. And of course Abimelech 
denies it, maybe he didn't know about it, and maybe it was because 
Abraham had never said it. And now Abraham does what is 
intrinsic to covenant keeping. With reference to this covenantal 
arrangement, most likely Abraham is the inferior and Abimelech 
is the superior. And so Abraham offers or takes 
sheep, oxen, and gives them to Abimelech, and the two of them 
made a covenant. Remember in Genesis chapter 15, 
when God makes a covenant with Abraham, The explanation I gave 
there, I tried to give there, was that when two parties made 
a covenant, they would take these animals, they would cut them 
right down the middle, and they would put them on either side. 
And then the parties of the covenant would walk between those pieces 
with the understanding that if either party broke the covenant, 
then whatever happened to those animals may have happened to 
that covenant breaker. Likely that's what Abraham and 
Abimelech are doing in this particular instance. They cut the animals, 
they walk through the animals, and technically that's the language 
with reference to covenant making. It's usually, the convention 
is, in the Hebrew Old Testament, to cut a covenant. You make them, 
sure. You ratify them, sure. You confirm 
them at certain points. But the fundamental and probably 
most often used sort of convention is to say, cut a covenant. And 
it probably has reference to cutting those animals so you 
can march between them and take that self-maledictory oath upon 
yourself. Now, beyond that, notice what 
Abraham does in verse 28. And Abraham set seven ewe lambs 
of the flock by themselves. Then Abimelech asked Abraham, 
what is the meaning of these seven ewe lambs which you have 
set by themselves? So this was over and above. This 
was not normal. This was different. This was 
an add-on. And that's when Abraham responds 
in verse 30. You will take these seven ewe 
lambs from my hand, that they may be my witness that I have 
dug this well. So the lambs go one step beyond 
the basic treaty to secure the water for Abraham. Now, for those 
of us who can wander over to a tap and flip it up and get 
water, we probably don't value wells like we should. But if 
we were in this situation and we were given our choice of the 
land, that land is absolutely positively useless without water. And so Abraham understands that 
if I don't have water, I don't have land. So above and beyond 
the common basic treaty and covenant to dwell peacefully among one 
another, Abraham ponies up these ewe lambs so that he will be 
assured of retaining this particular well. It is a piece of ownership 
in the land of Canaan. It's a down payment to what God 
has promised in terms of the full reception of the land, the 
nation of Canaan. Wenham again says he is giving 
extra animals because he wants more than a general treaty. He 
wants a specific concession, namely the guaranteed use of 
the well that he had dug. For without the right to water, 
a promise to be allowed to live in the land is valueless. Hence 
Abraham's determination to secure the use of the well. This is 
the land promise coming to fruition. We've got seed in Isaac, we've 
got land in Canaan. The Lord is faithful, brethren, 
and what may seem mundane and what may seem not earth-shattering, 
it's a well, but what it is is a proof positive that God's faithfulness 
is coming to play in his life. Now notice he names the place, 
so they call the place Beer Sheba, which literally means well of 
the oath or well of the seven. Beer means well and Sheba has 
either the meaning of oath or seven. Fits beautifully with 
either one. It's the well of the oath that 
they made between each other, to one another, or the seven, 
the seven new lambs that were that add-on to secure the well 
rights for Abraham at this particular instance. Thus they made a covenant 
at Beersheba. So Abimelech rose with Phicol, 
the commander of his army, and they returned to the land of 
the Philistines. Now note what Abraham does. Verse 33, Abraham 
planted a tamarisk tree in Beersheba, and there called on the name 
of the Lord, the everlasting God. Now, there's a lot of ways 
to understand why he planted this particular tree. From the 
mundane, you want big trees, shady trees in this part of the 
world. Again, for us who have air conditioning 
and, you know, an abundance of trees all around because it rains 
like it does, we just take this for granted. But if you were 
living in this climate, you would want trees, big leafy trees, 
big massive trees, so that you could have a siesta during the 
heat of the day. I mean, brethren, that's not 
just a thing in Mexico. It's too hot to work in some 
of these places. 15 minutes under a shade tree 
will rejuvenate you, enable you to work harder for the remaining 
workday. So some suggest that it's that. 
Others see the religious nature of it. Remember later on in redemptive 
history, what are forbidden? groves of trees, not because 
we hate trees, but because they were utilized for religious worship. So what Abraham starts off doing 
ultimately becomes perverted by the children of Israel. But 
at this particular time, it does seem to be connected to worship 
because Abraham plants this tamarisk tree in Beersheba and there calls 
on the name of the Lord. Notice the everlasting God. Beautiful way that Abraham calls 
on the Lord here as the everlasting God. Again, Wenham, I think, 
explains this well. The use of this divine epithet, 
which is El Olam, suggests that God's long-term faithfulness 
to Abraham has been revealed through Abimelech's words and 
actions. It's a Bimelech that is confirming 
God's covenant with reference to Abraham. In his opening speech, 
a Bimelech, he had looked confidently into the future with his descendants 
and Abraham's living peaceably together. By granting Abraham 
rights to a well, a Bimelech had made it possible for Abraham 
to live there permanently and had acknowledged his legal right 
at least to water. In other words, after so many 
delays, the promises of land and descendants at last seem 
on their way to fulfillment. So when you first read Genesis 
chapter 21, it's not just that this covenant with Abimelech 
is sort of tacked on because Oh yeah, we got to revisit Abimelech 
and he's living in the land of Gerar. No, it's the promises 
of God. They're yea and amen in our Lord 
Jesus Christ. God specified you will receive 
seed and you will receive land. It makes it, you know, that much 
more glorious when they receive the seed at the beginning of 
the chapter and they start receiving the land at the end of the chapter. 
If ever you are thinking your problems are big, read Genesis 
21 and 22. But as well, if ever you're doubting 
the covenant faithfulness of God, read Genesis 21 and 22. This is obviously for the people 
of God today to encourage confident faith in the living and true 
God, in the everlasting God, as Abraham addresses him. It's 
a beautiful epithet for Abraham to utilize at this particular 
time, which highlights the faithfulness of our covenant-keeping God, 
who gave land and who gave seed, as he said he would. Now let's 
turn, finally, to Galatians chapter 4, at least to read the section, 
to see how the Apostle Paul deals with this. For those of you who've 
ever read anything by John Calvin, when he talks about allegory, 
he says it was a contrivance of Satan. Allegory was a contrivance 
of Satan that was employed by many exegetes in the history 
of the church. He's not talking about Paul's 
allegory here. But Calvin certainly didn't have 
a lot of time for allegory. I've gotten a little bit more 
appreciative allegory as long as it is controlled by you know 
some textual sort of stipulation so perhaps I don't think I'd 
fall lockstep with Calvin but I certainly listened to his caution 
on that and we need to be careful there has to be textual controls 
when you get into allegory but with reference to Paul he's inspired 
by the Holy Spirit when he goes allegorical we can follow right 
along. Now notice in Galatians 4.21, 
tell me, you who desire to be under the law, do you not hear 
the law? For it is written that Abraham 
had two sons, the one by a bondwoman, the other by a free woman. But 
he who was of the bondwoman was born according to the flesh, 
and he of the free woman through promise. which things are symbolic, 
for these are the two covenants, the one from Mount Sinai, which 
gives birth to bondage, which is Hagar, for this Hagar is Mount 
Sinai in Arabia, and corresponds to Jerusalem, which now is, and 
is in bondage with her children. But the Jerusalem above is free, 
which is the mother of us all. For it is written, Rejoice, O 
barren, you who do not bear, break forth and shout, you who 
are not in labor. For the desolate has many more 
children than she who has a husband. Now we, brethren, as Isaac was, 
are children of promise. But as he who was born according 
to the flesh then persecuted him who was born according to 
the Spirit, even so it is now." So Paul applies this to the situation 
affecting the churches in Galatia. He is saying that these Judaizers 
that have come to you, that are saying faith in Jesus is good, 
plus circumcision for eternal life, they're like Ishmael. They're 
persecutors. They are sons of the flesh, and 
their whole desire is to make shipwreck of you. He says, according 
to the Spirit, even so it is now. Nevertheless, what does 
the Scripture say? Cast out the bondwoman and her 
son. Isn't that intriguing? What does 
the Scripture say? So when Sarah says what she is 
saying, that is by the inspiration and power of God Almighty. Cast 
out the bondwoman and her son, for the son of the bondwoman 
shall not be heir with the son of the free woman. So then, brethren, 
we are not children of the bondwoman, but of the free. We're connected 
to Isaac. We're connected to Abraham. We're 
connected to those men because it is from them that Jesus Christ 
came. Look at Galatians 3.26. For you 
are all sons of God through faith in Christ Jesus. For as many 
of you as were baptized into Christ have put on Christ. I 
think it's good for us to remind ourselves of Galatians 3 and 
4 as we move through the patriarchs, Abraham, Isaac, and Jacob. Because those men existed, yes, 
to populate Canaan at that particular time, yes, to have families, 
yes, to demonstrate true religion in the land, but primarily so 
that ultimately Messiah would come, ultimately Jesus would 
come, and it would be through him that we would have forgiveness 
of sins and life eternal. So Paul appeals to Genesis chapter 
21 in Galatians 4, he uses it allegorically to show spiritual 
truth from that situation facing Abraham and Sarah back in the 
day. Well let's close in a word of 
prayer. Our Father we thank you for your word and we thank you 
that it is given by inspiration of God and that it is profitable 
to us. And I pray that you would encourage 
our hearts as we see the scope of the scripture as Jesus Christ 
our Lord, and help us to see the consent of the parts and 
how it all works together, and how the apostle appeals to such 
things and uses them in a context many ways so separate from what 
originally obtained with Abraham and Sarah, and yet not much different. We thank you for the gospel of 
our salvation. We thank you for the seed of 
Abraham. even our Lord Jesus Christ, and the fact that through 
Him we are sons and daughters of Abraham. Go with us now, we 
pray, through Christ our Lord. Amen.
