Genesis 21:1-34
1 And the LORD visited Sarah as he had said, and the LORD did unto Sarah as he had spoken.
2 For Sarah conceived, and bare Abraham a son in his old age, at the set time of which God had spoken to him.
3 And Abraham called the name of his son that was born unto him, whom Sarah bare to him, Isaac.
4 And Abraham circumcised his son Isaac being eight days old, as God had commanded him.
5 And Abraham was an hundred years old, when his son Isaac was born unto him.
6 And Sarah said, God hath made me to laugh, so that all that hear will laugh with me.
7 And she said, Who would have said unto Abraham, that Sarah should have given children suck? for I have born him a son in his old age.
8 And the child grew, and was weaned: and Abraham made a great feast the same day that Isaac was weaned.
9 And Sarah saw the son of Hagar the Egyptian, which she had born unto Abraham, mocking.
10 Wherefore she said unto Abraham, Cast out this bondwoman and her son: for the son of this bondwoman shall not be heir with my son, even with Isaac.
11 And the thing was very grievous in Abraham's sight because of his son.
12 And God said unto Abraham, Let it not be grievous in thy sight because of the lad, and because of thy bondwoman; in all that Sarah hath said unto thee, hearken unto her voice; for in Isaac shall thy seed be called.
13 And also of the son of the bondwoman will I make a nation, because he is thy seed.
14 And Abraham rose up early in the morning, and took bread, and a bottle of water, and gave it unto Hagar, putting it on her shoulder, and the child, and sent her away: and she departed, and wandered in the wilderness of Beersheba.
15 And the water was spent in the bottle, and she cast the child under one of the shrubs.
16 And she went, and sat her down over against him a good way off, as it were a bowshot: for she said, Let me not see the death of the child. And she sat over against him, and lift up her voice, and wept.
17 And God heard the voice of the lad; and the angel of God called to Hagar out of heaven, and said unto her, What aileth thee, Hagar? fear not; for God hath heard the voice of the lad where he is.
18 Arise, lift up the lad, and hold him in thine hand; for I will make him a great nation.
19 And God opened her eyes, and she saw a well of water; and she went, and filled the bottle with water, and gave the lad drink.
20 And God was with the lad; and he grew, and dwelt in the wilderness, and became an archer.
21 And he dwelt in the wilderness of Paran: and his mother took him a wife out of the land of Egypt.
22 And it came to pass at that time, that Abimelech and Phichol the chief captain of his host spake unto Abraham, saying, God is with thee in all that thou doest:
23 Now therefore swear unto me here by God that thou wilt not deal falsely with me, nor with my son, nor with my son's son: but according to the kindness that I have done unto thee, thou shalt do unto me, and to the land wherein thou hast sojourned.
24 And Abraham said, I will swear.
25 And Abraham reproved Abimelech because of a well of water, which Abimelech's servants had violently taken away.
26 And Abimelech said, I wot not who hath done this thing: neither didst thou tell me, neither yet heard I of it, but to day.
27 And Abraham took sheep and oxen, and gave them unto Abimelech; and both of them made a covenant.
28 And Abraham set seven ewe lambs of the flock by themselves.
29 And Abimelech said unto Abraham, What mean these seven ewe lambs which thou hast set by themselves?
30 And he said, For these seven ewe lambs shalt thou take of my hand, that they may be a witness unto me, that I have digged this well.
31 Wherefore he called that place Beersheba;a because there they sware both of them.
32 Thus they made a covenant at Beersheba: then Abimelech rose up, and Phichol the chief captain of his host, and they returned into the land of the Philistines.
33 And Abraham planted a groveb in Beersheba, and called there on the name of the LORD, the everlasting God.
34 And Abraham sojourned in the Philistines' land many days.
The following commentary covers Chapter s 20 and 21.
In Chapter s 20, 21 we have the question of the heir and of the path of faith in another point of view. Abraham denies his relationship with his wife, and is reproved by the world itself, which knows better than he what she should be. God, however, guards the promises in His faithfulness, and judges that which meddles with her who has to say to them. The heir of promise is born; and the heir according to the flesh, son of the bondwoman or of the law, is entirely rejected. Now Abraham reproves the powerful of the earth, before whom he had previously denied his relationship with his wife.
But these two Chapter s must be somewhat more developed. Like Abram's going down to Egypt, we have unbelief working in respect of the path into which he had been called by grace, shewn, as it ever is, in reference to walking in the intimacy of the relationship in which God had set him, of which woman is the expression in the types. Here Sarah is the mother of the heir of the world, the wife of Abraham, according to promise, and, for Abraham, according to the church's hope, as we have seen (though Israel were the vessel according to flesh). This position he denies. Sarah is again his sister. This was worse than before, for she is, to faith, mother of the heir of the world. Abimelech was wrong, and acted to please himself, but acted unconscious of it. Abraham before God was in the falser position of the two. God warns Abimelech, and preserves Sarah by His own power, whom Abraham's want of faith had connected with the world; and Abimelech returns her, with the cutting reproof to the church, as here typified, that she at least ought to have known her own relationship to Christ. Still, in the main, Abraham was in the place of faith and blessing; and, as God's prophet, to whom none should do harm, intercedes for the faulty Abimelech, for here all is grace. There is another point to notice here, that this was an arrangement of unbelief when first he started from his father's house (Genesis 20:13), so soon was the germ of unbelief at work in the called of promise. But God maintains the divine title to the allegiance of the church at all times. But now the heir is born, the heir of promise.
The effect of this is, that not only is the difference known to faith, but the heir of the bondwoman is utterly cast out as to the inheritance. Historically he is preserved according to God's promise, a figure of legal Israel; but, as regards any portion of the inheritance, wholly cast out.
And here, further, Abraham fears no longer before the prince of this world, but reproves him. He has the world, as well as the heavenly communion, now that the heir is come; and the. world owns that God is with him in all things. Hence the well of the oath is the witness of Abraham's title in the world, and Abimelech's owning God to be with him. There, according to the oath and his title thus owned by the world, he plants a grove, takes possession of the earth, and worships, calling on the name of the everlasting God of Him who had once promised to Israel, and never abandoned His purpose, and had now accomplished on the earth what His mouth had spoken: not, indeed, so blessed a portion as the heavenly intercourse and possession of faith, but a proof of the unchangeable faithfulness of the God who had given the promises. There Abraham, in figure, now abides, where the power of the world had been. This will belong to Israel in the letter, but we, on whom the ends of the world are come, have it in a higher and better way. It was the pledge of what should be and will be; our hope is transferred to heaven where Christ is gone. But we reign there in a better way.
