Genesis 17:19-21 ▼

19 But God said, “No. Your wife Sarah will bear you a son, and you will name him Isaac. I will confirm my covenant with him as a permanent covenant for his future offspring.

20 As for Ishmael, I have heard you. I will certainly bless him; I will make him fruitful and will multiply him greatly. He will father twelve tribal leaders, and I will make him into a great nation.

21 But I will confirm my covenant with Isaac, whom Sarah will bear to you at this time next year.”
