19 God said, “No, Sarah your wife is going to bear you a son, and you will name him Isaac.[c] I will confirm my covenant with him as a perpetual[d] covenant for his descendants after him. 20 As for Ishmael, I have heard you.[e] I will indeed bless him, make him fruitful, and give him a multitude of descendants.[f] He will become the father of twelve princes;[g] I will make him into a great nation.
