18. Then Abraham said to God, “Please let Ishmael be the son you promised.”
19. God said, “No. Sarah your wife will have a son, and you will name him Isaac. I will make my agreement with him. It will be an agreement that continues forever with all his descendants.
20. “You asked me about Ishmael, and I heard you. I will bless him. I will give him many descendants. And I will cause their numbers to grow very greatly. He will be the father of 12 great leaders. I will make him into a great nation.
21. But I will make my agreement with Isaac. He is the son whom Sarah will have at this same time next year.”
22. After God finished talking with Abraham, God rose and left him.
