18. Abraham said to God, "I wish Ishmael could receive your blessing!"
19. Then God said, "I will bless Ishmael. But your wife Sarah will have a son by you. And you will name him Isaac. I will establish my covenant with him. It will be a covenant that lasts forever. It will be for Isaac and for his family after him.
20. "As for Ishmael, I have heard you. You can be sure that I will bless him. I will give him children. I will greatly increase his numbers. He will be the father of 12 rulers. And I will make him into a great nation.
21. "But I will establish my covenant with Isaac. By this time next year, Sarah will have a son by you."
22. When he had finished speaking with Abraham, God left him.
