Genesis 17:10–27

¹⁰This is my covenant, which you shall keep, between me and you and your descendants after you: Every male among you shall be circumcised. ¹¹You shall be circumcised in the flesh of your foreskins, and it shall be a sign of the covenant between me and you. ¹²He that is eight days old among you shall be circumcised; every male throughout your generations, whether born in your house, or bought with your money from any foreigner who is not of your offspring, ¹³both he that is born in your house and he that is bought with your money, shall be circumcised. So shall my covenant be in your flesh an everlasting covenant. ¹⁴Any uncircumcised male who is not circumcised in the flesh of his foreskin shall be cut off from his people; he has broken my covenant.”

¹⁵And God said to Abraham, “As for Sarai your wife, you shall not call her name Sarai, but Sarah shall be her name. 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.
