Genesis 17:10-13 ▼

10 This is My covenant with you and your descendants after you, which you are to keep: Every male among you must be circumcised.

11 You are to circumcise the flesh of your foreskin, and this will be a sign of the covenant between Me and you.

12 Generation after generation, every male must be circumcised when he is eight days old, including those born in your household and those purchased from a foreigner— even those who are not your offspring.

13 Whether they are born in your household or purchased, they must be circumcised. My covenant in your flesh will be an everlasting covenant.
