Genesis 17:11-14 ▼

11 You must circumcise the flesh of your foreskin to serve as a sign of the covenant between me and you.

12 Throughout your generations, every male among you is to be circumcised at eight days old—every male born in your household or purchased from any foreigner and not your offspring.

13 Whether born in your household or purchased, he must be circumcised. My covenant will be marked in your flesh as a permanent 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.”
