6. I will make you exceedingly fruitful, and I will make you into nations, and kings shall come from you.
7. And I will establish my covenant between me and you and your offspring after you throughout their generations for an everlasting covenant, to be God to you and to your offspring after you.
8. And I will give to you and to your offspring 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 offspring after you throughout their generations.
10. This is my covenant, which you shall keep, between me and you and your offspring 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 who 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 who is born in your house and he who is bought with your money, shall surely 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 Sarai your wife, you shall not call her name Sarai, 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 become 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, “Oh that Ishmael might live before you!”
19. God said, “No, but Sarah your wife shall bear you a son, and you shall call his name Isaac. I will establish my covenant with him as an everlasting covenant for his offspring after him.
