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. I will keep my covenant with him and with his descendants for ever. It is an everlasting covenant.
20. I have heard your request about Ishmael, so I will bless him and give him many children and many descendants. He will be the father of twelve princes, and I will make a great nation of his descendants.
21. But I will keep my covenant with your son Isaac, who will be born to Sarah about this time next year.”
