2 Sarah conceived, and bore Abraham a son in his old age, at the set time of which God had spoken to him.
For it is written that Abraham had two sons, one by the handmaid, and one by the free woman.
By faith, even Sarah herself received power to conceive, and she bore a child when she was past age, since she counted him faithful who had promised.
God said, "No, but Sarah, your wife, will bear you a son. You shall call his name Isaac.{Isaac means "he laughs."} I will establish my covenant with him for an everlasting covenant for his seed after him.
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.
He gave him the covenant of circumcision. So Abraham became the father of Isaac, and circumcised him the eighth day. Isaac became the father of Jacob, and Jacob became the father of the twelve patriarchs.
He said, At this season, when the time comes round, you shall embrace a son. She said, No, my lord, you man of God, do not lie to your handmaid. The woman conceived, and bore a son at that season, when the time came round, as Elisha had said to her.
Behold, Elizabeth, your relative, also has conceived a son in her old age; and this is the sixth month with her who was called barren.

Long-looked-for comes at last. The vision concerning the promised seed is for an appointed time, and now, at the end, it speaks, and does not lie; few under the Old Testament were brought into the world with such expectation as Isaac was, not for the sake of any great person eminence at which he was to arrive, but because he was to be, in this very thin, a type of Christ, that seed which the holy God had so long promised and holy men so long expected. In this account of the first days of Isaac we may observe,
Gen 21:9-13
The casting out of Ishmael is here considered of, and resolved on.
Gen 21:14-21
Here is,
Gen 21:22-32
We have here an account of the treaty between Abimelech and Abraham, in which appears the accomplishment of that promise (ch. 12:2) that God would make his name great. His friendship is valued, is courted, though a stranger, though a tenant at will to the Canaanites and Perizzites.
Gen 21:33-34
Observe,
