18. And he said to God, "If only Ishmael would live in your sight."
19. And God said to Abraham: "Your wife Sarah shall give birth to a son, and you shall call his name Isaac, and I will establish my covenant with him as a perpetual covenant, and with his offspring after him.
20. Likewise, concerning Ishmael, I have heard you. Behold, I will bless and enlarge him, and I will multiply him greatly. He will produce twelve leaders, and I will make him into a great nation.
21. Yet in truth, I will establish my covenant with Isaac, to whom Sarah will give birth for you at this time next year."
22. And when he had finished speaking with him, God ascended from Abraham.
23. Then Abraham took his son Ishmael, and all who were born in his house, and all whom he had bought, every male among the men of his house, and he circumcised the flesh of their foreskin promptly, the very same day, just as God had instructed him.
24. Abraham was ninety-nine years old when he circumcised the flesh of his foreskin.
