9 And God said again unto Abraham, Thou shalt keep my covenant therefore, thou and thy seed after thee in their generations.
10 This shall be my covenant, which ye shall keep between me and you and thy seed after thee: Every male among you shall be circumcised.
11 And ye shall circumcise the flesh of your foreskin, and it shall be a token of the covenant between me and you.
12 And he that is eight days old shall be circumcised among you, every male in your generations, he that is born in the house or bought with money of any stranger, who is not of thy seed.
13 He 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.
14 And the uncircumcised male whose flesh of his foreskin is not circumcised, that person shall be cut off from his people; he has annulled my covenant.
15 And God said unto Abraham, As for Sarai thy wife, thou shalt not call her name Sarai, but Sarah shall her name be.
