Genesis 17:19 In-Context

17 Then Abraham fell on his face and laughed, and said to himself, "Can a child be born to a man who is a hundred years old? Can Sarah, who is ninety years old, bear a child?"
18 And Abraham said to God, "O that Ishmael might live in your sight!"
19 God said, "No, but your wife Sarah shall bear you a son, and you shall name him Isaac. I will establish my covenant with him as an everlasting covenant for his offspring after him.
20 As for Ishmael, I have heard you; I will bless him and make him fruitful and exceedingly numerous; he shall be the father of twelve princes, and I will make him a great nation.
21 But my covenant I will establish with Isaac, whom Sarah shall bear to you at this season next year."
