21 But my covenant I establish with Isaac, whom Sarah will bear to you at this set time in the next year."
He said, "I will certainly return to you when the season comes round. Behold, Sarah your wife will have a son." Sarah heard in the tent door, which was behind him.
Yahweh appeared to him, and said, "Don't go down into Egypt. Dwell in the land which I will tell you of. Sojourn in this land, and I will be with you, and will bless you. For to you, and to your seed, I will give all these lands, and I will establish the oath which I swore to Abraham your father. I will multiply your seed as the stars of the sky, and will give to your seed all these lands. In your seed will all the nations of the earth be blessed, because Abraham obeyed my voice, and kept my charge, my commandments, my statutes, and my laws."
Therefore she said to Abraham, "Cast out this handmaid and her son! For the son of this handmaid will not be heir with my son, even with Isaac." The thing was very grievous in Abraham's sight on account of his son. God said to Abraham, "Don't let it be grievous in your sight because of the boy, and because of your handmaid. In all that Sarah says to you, listen to her voice. For from Isaac will your seed be called.
Israel traveled with all that he had, and came to Beersheba, and offered sacrifices to the God of his father, Isaac.
Moreover he said, "I am the God of your father, the God of Abraham, the God of Isaac, and the God of Jacob." Moses hid his face; for he was afraid to look at God.
"Oh that you would hide me in Sheol, That you would keep me secret, until your wrath is past, That you would appoint me a set time, and remember me!
To show mercy towards our fathers, To remember his holy covenant,
He said to them, "It isn't for you to know times or seasons which the Father has set within His own authority.
For this is a word of promise, "At the appointed time I will come, and Sarah will have a son."
If you are Christ's, then you are Abraham's seed and heirs according to promise.

CHAPTER 17
Ge 17:1-27. Renewal of the Covenant.
1. Abram … ninety years old and nine—thirteen years after the birth of Ishmael [Ge 16:16]. During that interval he had enjoyed the comforts of communion with God but had been favored with no special revelation as formerly, probably on account of his hasty and blameable marriage with Hagar.
the Lord appeared—some visible manifestation of the divine presence, probably the Shekinah or radiant glory of overpowering effulgence.
I am the Almighty God—the name by which He made Himself known to the patriarchs (Ex 6:3), designed to convey the sense of "all-sufficient" (Ps 16:5, 6; 73:25).
walk … and … perfect—upright, or sincere (Ps 51:6) in heart, speech, and behavior.
3. Abram fell on his face—the attitude of profoundest reverence assumed by Eastern people. It consists in the prostrate body resting on the hands and knees, with the face bent till the forehead touches the ground. It is an expression of conscious humility and profound reverence.
4. my covenant is with thee—Renewed mention is made of it as the foundation of the communication that follows. It is the covenant of grace made with all who believe in the Saviour.
5. but thy name shall be Abraham—In Eastern countries a change of name is an advertisement of some new circumstance in the history, rank, or religion of the individual who bears it. The change is made variously, by the old name being entirely dropped for the new, or by conjoining the new with the old; or sometimes only a few letters are inserted, so that the altered form may express the difference in the owner's state or prospects. It is surprising how soon a new name is known and its import spread through the country. In dealing with Abraham and Sarai, God was pleased to adapt His procedure to the ideas and customs of the country and age. Instead of Abram, "a high father," he was to be called Abraham, "father of a multitude of nations" (see Re 2:17).
8. I will give unto thee … the land—It had been previously promised to Abraham and his posterity (Ge 15:18). Here it is promised as an "everlasting possession," and was, therefore, a type of heaven, "the better country" (Heb 11:16).
10. Every man child among you shall be circumcised—This was the sign in the Old Testament Church as baptism is in the New, and hence the covenant is called "covenant of circumcision" (Ac 7:8; Ro 4:11). The terms of the covenant were these: on the one hand Abraham and his seed were to observe the right of circumcision; and on the other, God promised, in the event of such observance, to give them Canaan for a perpetual possession, to be a God to him and his posterity, and that in him and his seed all nations should be blessed.
15, 16. As for Sarai … I will … give thee a son also of her—God's purposes are gradually made known. A son had been long ago promised to Abraham. Now, at length, for the first time he is informed that it was to be a child of Sarai.
17. Abraham fell upon his face, and laughed—It was not the sneer of unbelief, but a smile of delight at the improbability of the event (Ro 4:20).
18. O that Ishmael might live before thee—natural solicitude of a parent. But God's thoughts are not as man's thoughts [Isa 55:8].
19, 20. The blessings of the covenant are reserved for Isaac, but common blessings were abundantly promised to Ishmael; and though the visible Church did not descend from his family, yet personally he might, and it is to be hoped did, enjoy its benefits.
