16 And I will give her a blessing so that you will have a son by her: truly my blessing will be on her, and she will be the mother of nations: kings of peoples will be her offspring.
And he said, I will certainly come back to you in the spring, and Sarah your wife will have a son. And his words came to the ears of Sarah who was at the back of the tent-door. Now Abraham and Sarah were very old, and Sarah was past the time for giving birth. And Sarah, laughing to herself, said, Now that I am used up am I still to have pleasure, my husband himself being old? And the Lord said, Why was Sarah laughing and saying, Is it possible for me, being old, to give birth to a child? Is there any wonder which the Lord is not able to do? At the time I said, in the spring, I will come back to you, and Sarah will have a child.
But the Jerusalem on high is free, which is our mother. For it is in the Writings, You who have never given birth, be glad; give cries of joy, you who have had no birth-pains; for the children of her who has been given up by her husband are more than those of the woman who has a husband. Now we, brothers, as Isaac was, are the children of the undertaking of God. But as in those days he who had birth after the flesh was cruel to him who had birth after the Spirit, even so it is now. What then do the Writings say? Send away the servant-woman and her son; for the son of the servant-woman will not have a part in the heritage with the son of the free woman. So, brothers, we are not children of the servant-woman, but of the free woman.

Commentary on Genesis 17 Matthew Henry Commentary
Chapter 17
This chapter contains articles of agreement covenanted and concluded upon between the great Jehovah, the Father of mercies, on the one part, and pious Abram, the father of the faithful, on the other part. Abram is therefore called "the friend of God,' not only because he was the man of his counsel, but because he was the man of his covenant; both these secrets were with him. Mention was made of this covenant (ch. 15:18), but here it is particularly drawn up, and put into the form of a covenant, that Abram might have strong consolation. Here are,
Gen 17:1-3
Here is,
Gen 17:4-6
The promise here is introduced with solemnity: "As for me,' says the great God, "behold, behold and admire it, behold and be assured of it, my covenant is with thee;' as before (v. 2), I will make my covenant. Note, The covenant of grace is a covenant of God's own making; this he glories in (as for me), and so may we. Now here,
Gen 17:7-14
Here is,
Gen 17:15-22
Here is,
Gen 17:23-27
We have here Abraham's obedience to the law of circumcision. He himself and all his family were circumcised, so receiving the token of the covenant and distinguishing themselves from other families, that had no part nor lot in the matter.
