18. So Abraham said to God, “If only Ishmael could live in your favor!”
19. God replied: Even so, your wife Sarah is to bear you a son, and you shall call him Isaac. It is with him that I will maintain my covenant as an everlasting covenant and with his descendants after him.
20. Now as for Ishmael, I will heed you: I hereby bless him. I will make him fertile and will multiply him exceedingly. He will become the father of twelve chieftains, and I will make of him a great nation.
21. But my covenant I will maintain with Isaac, whom Sarah shall bear to you by this time next year.
