BSB(i)
19 But God replied, “Your wife Sarah will indeed bear you a son, and you are to name him Isaac. I will establish My covenant with him as an everlasting covenant for his descendants after him.
20 As for Ishmael, I have heard you, and I will surely bless him; I will make him fruitful and multiply him greatly. He will become the father of twelve rulers, and I will make him into a great nation.
21 But I will establish My covenant with Isaac, whom Sarah will bear to you at this time next year.”
