1And when Abram was ninety-nine years old, the LORD appeared to Abram and said to him, "I am the Almighty God! Walk before Me and be perfect.

2And I will make My covenant between Me and you, and will multiply you exceedingly."

3And Abram fell on his face. And God talked with him, saying,

4"As for Me, behold, My covenant is with you, and you shall be a father of many nations.

5Neither shall your name any more be called Abram, but your name shall be Abraham; for I have made you a father of many nations.

6And I will make you exceedingly fruitful, and I will make nations of you, and kings shall come from you. 7And I will establish My covenant between Me and you and your seed after you in their generations for an everlasting covenant, to be God to you and to your seed after you. 8And I will give the land to you in which you are a sojourner, and to your seed after you, all the land of Canaan, for an everlasting possession. And I will be their God."

9And God said to Abraham, "And you shall keep My covenant, you and your seed after you in their generations. 10This is My covenant, which you shall keep, between Me and you and your seed after you. Every male child among you shall be circumcised. 11And you shall circumcise the flesh of your foreskin. And it shall be a sign of the covenant between Me and you. 12And a son of eight days shall be circumcised among you, every male child in your generations; he that is born in the house, or bought with silver of any foreigner who is not of your seed. 13He that is born in your house, and he that is bought with your silver, must be circumcised. And My covenant shall be in your flesh for an everlasting covenant. 14And the uncircumcised male child whose flesh of his foreskin is not circumcised, that soul shall be cut off from his people--for he has broken My covenant."

15And God said to Abraham, "As for Sarai your wife, you shall not call her name Sarai, but her name shall be Sarah. 16And I will bless her, and give you a son also of her. Yes, I will bless her, and she shall be a mother of nations--kings of people shall be from her." 17And Abraham fell upon his face and laughed, and said in his heart, "Shall a child be born to him that is a hundred years old? And shall Sarah, who is ninety years old, bear?" 18And Abraham said to God, "Oh, that Ishmael might live before You!" 19And God said, "Sarah your wife shall bear you a son indeed. And you shall call his name Isaac. And I will establish My covenant with him for an everlasting covenant, and with his seed after him. 20And as for Ishmael, I have heard you. Behold, I have blessed him, and will make him fruitful, and will multiply him exceedingly. He shall beget twelve princes, and I will make him a great nation. 21But I will establish My covenant with Isaac, whom Sarah shall bear to you at this set time in the next year." 22And He left off talking with him, and God went up from Abraham.

23And Abraham took his son Ishmael, and all that were born in his house, and all that were bought with his silver--every male among the men of Abraham's house--and circumcised the flesh of their foreskins in the same day, even as God said to him. 24And Abraham was ninety-nine years old when he was circumcised in the flesh of his foreskin. 25And his son Ishmael was thirteen years old when he was circumcised in the flesh of his foreskin. 26In the same day Abraham and his son Ishmael were circumcised. 27And all the men of his house that were born in the house, or bought with silver from the foreigner, were circumcised with him.
