17:19 God said, “No, Sarah your wife is going to bear you a son, and you will name him Isaac. 1 I will confirm my covenant with him as a perpetual 2 covenant for his descendants after him. 17:20 As for Ishmael, I have heard you. 3 I will indeed bless him, make him fruitful, and give him a multitude of descendants. 4 He will become the father of twelve princes; 5 I will make him into a great nation.
