9 God said to Abraham, "As for you, you must keep my covenant, you and your descendants in every generation.
10 This is my covenant that you and your descendants must keep: Circumcise every male.
11 You must circumcise the flesh of your foreskins, and it will be a symbol of the covenant between us.
12 On the eighth day after birth, every male in every generation must be circumcised, including those who are not your own children: those born in your household and those purchased with silver from foreigners.
13 Be sure you circumcise those born in your household and those purchased with your silver. Your flesh will embody my covenant as an enduring covenant.
14 Any uncircumcised male whose flesh of his foreskin remains uncircumcised will be cut off from his people. He has broken my covenant."
15 God said to Abraham, "As for your wife Sarai, you will no longer call her Sarai. Her name will now be Sarah.
