17:9And God said unto Abraham, And as for thee, thou shalt keep my covenant, thou, and thy seed after thee throughout their generations. 17:10This is my covenant, which ye shall keep, between me and you and thy seed after thee: every male among you shall be circumcised. 17:11And ye shall be circumcised in the flesh of your foreskin; and it shall be a token of a covenant betwixt me and you. 17:12And he that is eight days old shall be circumcised among you, every male throughout your generations, he that is born in the house, or bought with money of any foreigner that is not of thy seed. 17:13He that is born in thy house, and he that is bought with thy money, must needs be circumcised: and my covenant shall be in your flesh for an everlasting covenant. 17:14And the uncircumcised male who is not circumcised in the flesh of his foreskin, that soul shall be cut off from his people; he hath broken my covenant.
17:15And God said unto Abraham, As for Sarai thy wife, thou shalt not call her name Sarai, but Sarah shall her name be. 17:16And I will bless her, and moreover I will give thee a son of her: yea, I will bless her, and she shall be a mother of nations; kings of peoples shall be of her. 17:17Then Abraham fell upon his face, and laughed, and said in his heart, Shall a child be born unto him that is a hundred years old? and shall Sarah, that is ninety years old, bear? 17:18And Abraham said unto God, Oh that Ishmael might live before thee! 17:19And God said, Nay, but Sarah thy wife shall bear thee a son; and thou shalt call his name Isaac: and I will establish my covenant with him for an everlasting covenant for his seed after him. 17:20And as for Ishmael, I have heard thee: behold, I have blessed him, and will make him fruitful, and will multiply him exceedingly; twelve princes shall he beget, and I will make him a great nation. 17:21But my covenant will I establish with Isaac, whom Sarah shall bear unto thee at this set time in the next year.
17:22And he left off talking with him, and God went up from Abraham. 17:23And Abraham took Ishmael his son, and all that were born in his house, and all that were bought with his money, every male among the men of Abraham's house, and circumcised the flesh of their foreskin in the selfsame day, as God had said unto him. 17:24And Abraham was ninety years old and nine, when he was circumcised in the flesh of his foreskin. 17:25And Ishmael his son was thirteen years old, when he was circumcised in the flesh of his foreskin. 17:26In the selfsame day was Abraham circumcised, and Ishmael his son. 17:27And all the men of his house, those born in the house, and those bought with money of a foreigner, were circumcised with him.
