Genesis 17:7-19

Revised Standard Version

⁷ And I will establish my covenant between me and you and your descendants after you throughout their generations for an everlasting covenant, to be God to you and to your descendants after you. ⁸ And I will give to you, and to your descendants after you, the land of your sojournings, all the land of Canaan, for an everlasting possession; and I will be their God.”

⁹ And God said to Abraham, “As for you, you shall keep my covenant, you and your descendants after you throughout their generations. ¹⁰ This is my covenant, which you shall keep, between me and you and your descendants after you: Every male among you shall be circumcised. ¹¹ You shall be circumcised in the flesh of your foreskins, and it shall be a sign of the covenant between me and you. ¹² He 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, ¹³ both 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. ¹⁴ Any uncircumcised male who is not circumcised in the flesh of his foreskin shall be cut off from his people; he has broken my covenant.”

¹⁵ And God said to Abraham, “As for Sar′ai your wife, you shall not call her name Sar′ai, but Sarah shall be her name. ¹⁶ I 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.” ¹⁷ Then 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?” ¹⁸ And Abraham said to God, “O that Ish′mael might live in thy sight!” ¹⁹ God said, “No, but Sarah your wife shall bear you a son, and you shall call his name Isaac.^[a] I will establish my covenant with him as an everlasing covenant for his descendants after him.
