1When Abram was ninety-nine years old, God appeared to him, and said to him, "I am El Shaddai. Walk before me, and be blameless.

2I will make my covenant between me and you, and will multiply you greatly."

3Then Abram fell facedown, and God talked with him, saying,

4"As for me, look, my covenant is with you. You will be the father of a multitude of nations.

5Neither will your name any more be called Abram, but your name will be Abraham; for I will make you the father of a multitude of nations.

6I will make you exceedingly fruitful, and I will make nations of you. Kings will come out of you. 7I will establish my covenant between me and you and your descendants after you throughout their generations as an everlasting covenant, to be God to you and to your descendants after you. 8I will give to you, and to your descendants after you, the land of your sojournings, all the land of Canaan, as an everlasting possession, and I will be their God."

9God said to Abraham, "As for you, you are to keep my covenant, you and your descendants after you throughout their generations. 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 foreskin. It will be a sign of the covenant between me and you. 12He who is eight days old will be circumcised among you, every male throughout your generations, he who is born in the house, or bought with money from any foreigner who is not of your descendants. 13He who is born in your house, and he who is bought with your money, must be circumcised. My covenant will be in your flesh as an everlasting covenant. 14And the uncircumcised male who is not circumcised in the flesh of his foreskin on the eighth day, that person shall be cut off from his people. He has broken my covenant."

15God said to Abraham, "As for Sarai your wife, you shall not call her name Sarai, but her name will be Sarah. 16And I will bless her, and moreover I will give you a son by her. And I will bless her, and she will be a mother of nations. Kings of peoples will come from her." 17Then Abraham fell on his face, and laughed, and said in his heart, "Will a child be born to him who is one hundred years old? Will Sarah, who is ninety years old, give birth?" 18Abraham said to God, "Oh that Ishmael might live before you." 19And God said, "Truly, Sarah your wife will bear you a son, and you are to name him Isaac. And I will establish my covenant with him as an everlasting covenant and with his descendants after him. 20As for Ishmael, I have heard you. Look, I have blessed him, and will make him fruitful, and will multiply him exceedingly. He will become the father of twelve princes, and I will make him a great nation. 21But my covenant I establish with Isaac, whom Sarah will bear to you at this set time next year." 22When he finished talking with him, God went up from Abraham.

23Abraham took Ishmael his son, all who were born in his house, and all who were bought with his money; every male among the men of Abraham's house, and circumcised the flesh of their foreskin in the same day, as God had said to him. 24Abraham was ninety-nine years old, when he was circumcised in the flesh of his foreskin. 25Ishmael, his son, was thirteen years old when he was circumcised in the flesh of his foreskin. 26In the same day both Abraham and Ishmael, his son, were circumcised. 27All the men of his house, those born in the house, and those bought with money from a foreigner, were circumcised with him.
