ISV(i)
19 But God replied, “No, but your wife Sarah will give birth to your son, and you are to name him Isaac. I’ll confirm my covenant with him as an eternal covenant for his descendants.
20 And as for Ishmael, I’ve heard you. I’ll bless him, and he’ll have many descendants. I will multiply him greatly, he’ll father twelve tribal leaders, and I’ll cause his descendants to become a great nation.
21 Now as to Isaac, I’ll confirm my covenant with him, to whom Sarah will give birth as your son at this time next year.”
