9 God also said to Abraham, “As for you, you and your offspring after you throughout their generations are to keep My covenant.
10 This is My covenant, which you are to keep, between Me and you and your offspring after you: Every one of your males must be circumcised.
11 You must cut off the flesh of your foreskin as a sign of the covenant between me and you.
12 From generation to generation, every male child must be circumcised on the eighth day after his birth. This applies not only to members of your family but also to the servants born in your household and the foreign-born servants whom you have purchased.
13 a slave born in your house, as well as one purchased with money, must be circumcised. My covenant will be marked in your flesh as an everlasting covenant.
14 If any male is not circumcised in the flesh of his foreskin, that man will be cut off from his people; he has broken My covenant."
