9 And God said to Abraham, You shall keep my covenant therefore, you and your descendants after you in their generations.
10 This is my covenant, which you shall keep, between me and you and your descendants after you: Every male child among you shall be circumcised.
11 And you shall circumcise the flesh of your foreskin; and it shall be a sign of the covenant between me and you.
12 And he who is eight days old shall be circumcised among you, every male child in your generations, he who is born in the house or bought with money from any foreigner who is not your descendant.
13 He who is born in your house and he who is bought with your money must be circumcised, and my covenant shall be in your flesh for an everlasting covenant.
14 And the uncircumcised male child whose flesh of his foreskin is not circumcised, that person shall be cut off from his people; he has broken my covenant.
15 And God said to Abraham, As for Sarai your wife, you shall not call her name Sarai, but Sarah shall her name be.
