Genesis 17:4-14

4“As for me, this is my covenant with you: You will be the father of a multitude of nations.

5No longer will your name be Abram. Instead, your name will be Abraham because I will make you the father of a multitude of nations.

6I will make you extremely fruitful. I will make nations of you, and kings will descend from you.

7I will confirm my covenant as a perpetual covenant between me and you. It will extend to your descendants after you throughout their generations. I will be your God and the God of your descendants after you.

8I will give the whole land of Canaan – the land where you are now residing – to you and your descendants after you as a permanent possession. I will be their God.”

9Then God said to Abraham, “As for you, you must keep the covenantal requirement I am imposing on you and your descendants after you throughout their generations.

10This is my requirement that you and your descendants after you must keep: Every male among you must be circumcised.

11You must circumcise the flesh of your foreskins. This will be a reminder of the covenant between me and you.

12Throughout your generations every male among you who is eight days old must be circumcised, whether born in your house or bought with money from any foreigner who is not one of your descendants.

13They must indeed be circumcised, whether born in your house or bought with money. The sign of my covenant will be visible in your flesh as a permanent reminder.

14Any uncircumcised male who has not been circumcised in the flesh of his foreskin will be cut off from his people – he has failed to carry out my requirement.”
