Genesis 17:15-19

Good News Translation

¹⁵ God said to Abraham, “You must no longer call your wife Sarai; from now on her name is Sarah.^{[a] 16} I will bless her, and I will give you a son by her. I will bless her, and she will become the mother of nations, and there will be kings among her descendants.”

¹⁷ Abraham bowed down with his face touching the ground, but he began to laugh when he thought, “Can a man have a child when he is a hundred years old? Can Sarah have a child at ninety?” ¹⁸ He asked God, “Why not let Ishmael be my heir?”

¹⁹ But God said, “No. Your wife Sarah will bear you a son and you will name him Isaac.^[b] I will keep my covenant with him and with his descendants forever. It is an everlasting covenant.
