Genesis 17:16–27

¹⁶I will bless her, and moreover I will give you a son by her; I will bless her, and she shall be a mother of nations; kings of peoples shall come from her.” ¹⁷Then Abraham fell on his face and laughed, and said to himself, “Shall a child be born to a man who is a hundred years old? Shall Sarah, who is ninety years old, bear a child?” ¹⁸And Abraham said to God, “O that Ishmael might live in thy sight!” ¹⁹God said, “No, but Sarah your wife shall bear you a son, and you shall call his name Isaac.^z I will establish my covenant with him as an everlasting covenant for his descendants after him. ²⁰As for Ishmael, I have heard you; behold, I will bless him and make him fruitful and multiply him exceedingly; he shall be the father of twelve princes, and I will make him a great nation. ²¹But I will establish my covenant with Isaac, whom Sarah shall bear to you at this season next year.”

²²When he had finished talking with him, God went up from Abraham. ²³Then Abraham took Ishmael his son and all the slaves born in his house or bought with his money, every male among the men of Abraham’s house, and he circumcised the flesh of their foreskins that very day, as God had said to him. ²⁴Abraham was ninety-nine years old when he was circumcised in the flesh of his foreskin. ²⁵And Ishmael his son was thirteen years old when he was circumcised in the flesh of his foreskin. ²⁶That very day Abraham and his son Ishmael were circumcised; ²⁷and all the men of his house, those born in the house and those bought with money from a foreigner, were circumcised with him.
