Genesis 17:10-13 ▼

10 Here is my covenant that you are to observe, between me and you and your descendants: Every male among you is to be circumcised.

11 You are all to be circumcised in the flesh of your foreskin, and this is to be the sign of the covenant between me and you.

12 Generation after generation, every male among you is to be circumcised on the eighth day after his birth, including the servant born in your house or the one purchased from a foreigner, who is not of your offspring.

13 The servant born in your house or the one purchased with money is to be circumcised. My covenant is to remain in your flesh as an eternal covenant.
