New International Version
19 Then God said, “Yes, but your wife Sarah will bear you a son,(A) and you will call him Isaac.[a](B) I will establish my covenant with him(C) as an everlasting covenant(D) for his descendants after him. 20 And as for Ishmael, I have heard you: I will surely bless him; I will make him fruitful and will greatly increase his numbers.(E) He will be the father of twelve rulers,(F) and I will make him into a great nation.(G) 21 But my covenant(H) I will establish with Isaac, whom Sarah will bear to you(I) by this time next year.”(J)
