1Abram was ninety-nine years old. Jehovah appeared to him and said: »I am God Almighty. Walk before me and be blameless. 2»I will establish my covenant between us. I will greatly increase your numbers.« 3Abram fell on his face and God said to him: 4»This is my covenant with you: You will be the father of many nations. 5»You will no longer be called Abram Exalted Father. Your name will be Abraham means Father of Many. I have made you a father of many nations. 6»I will make you very fruitful. I will make nations of you, and kings will come from you. 7»I will establish my covenant as a long lasting covenant between us. It will be for your descendants after you, for the generations to come. I will be your God and the God of your descendants after you. 8»The whole land of Canaan, where you are now a guest alienforeignerstranger, I will give a long lasting possession to you and your descendants after you. I will be their God.« 9Then God said to Abraham: »As for you, you must keep my covenant, you and your descendants after you for the generations to come. 10»This is my covenant with you and your descendants after you, the covenant you are to keep: Every male among you shall be circumcised. 11»You are to undergo circumcision. It will be the sign of the covenant between us. 12»For the generations to come every male among you who is eight days old must be circumcised. This includes those born in your household or bought with money from a foreigner, those who are not your offspring. 13»Whether born in your household or bought with your money, they must be circumcised. My covenant in your flesh is to be a long lasting covenant. 14»Any male not circumcised in the flesh will be cut off from his people. He has broken my covenant.« 15God continued: »Do not call your wife Sarai any longer. Her name will be Sarah. 16»I will bless her and will surely give you a son by her. I will bless her so that she will be the mother of nations. Kings of peoples will come from her.« 17Abraham fell to his face. He laughed and said to himself: »Will a son be born to a man a hundred years old? Will Sarah bear a child at the age of ninety?« 18Abraham said to God: »If only Ishmael might live under your blessing!« 19God replied: »Yes, but your wife Sarah will bear you a son! You will call him Isaac. I will establish my covenant with him as a long lasting covenant for his descendants after him. 20»Concerning Ishmael, I have heard you: I will surely bless him. I will make him fruitful and will greatly increase his numbers. He will be the father of twelve rulers, and I will make him into a great nation. 21»But my covenant I will establish with Isaac. Sarah will bear him to you by this time next year.« 22When he finished speaking with Abraham, God went up from him. 23On that very day Abraham took his son Ishmael and all those born in his household or bought with his money, every male in his household, and circumcised them, as God told him. 24Abraham was ninety-nine years old when he was circumcised. 25His son Ishmael was thirteen. 26Abraham and his son Ishmael were both circumcised on that same day. 27Every male in Abraham’s household, including those born in his household or bought from a foreigner, was circumcised with him.
