1 When Abram was ninety-nine years old, God showed up and said to him, "I am The Strong God, live entirely before me, live to the hilt! I'll make a covenant between us and I'll give you a huge family." 3 Overwhelmed, Abram fell flat on his face. Then God said to him, "This is my covenant with you: You'll be the father of many nations. Your name will no longer be Abram, but Abraham, meaning that 'I'm making you the father of many nations.' I'll make you a father of fathers - I'll make nations from you, kings will issue from you. I'm establishing my covenant between me and you, a covenant that includes your descendants, a covenant that goes on and on and on, a covenant that commits me to be your God and the God of your descendants. And I'm giving you and your descendants this land where you're now just camping, this whole country of Canaan, to own forever. And I'll be their God."
9 God continued to Abraham, "And you: You will honor my covenant, you and your descendants, generation after generation. This is the covenant that you are to honor, the covenant that pulls in all your descendants: Circumcise every male. Circumcise by cutting off the foreskin of the penis; it will be the sign of the covenant between us. Every male baby will be circumcised when he is eight days old, generation after generation - this includes house-born slaves and slaves bought from outsiders who are not blood kin. Make sure you circumcise both your own children and anyone brought in from the outside. That way my covenant will be cut into your body, a permanent mark of my permanent covenant. An uncircumcised male, one who has not had the foreskin of his penis cut off, will be cut off from his people - he has broken my covenant."
