Genesis 17:4-14

4“For My part, because My covenant is with you, you will be the father of a multitude of nations.

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

6Yes, I will make you exceedingly fruitful, and I will make you into nations, and kings will come forth from you.

7Yes, I will establish My covenant between Me and you and your seed after you throughout their generations for an everlasting covenant, in order to be your God and your seed’s God after you.

8I will give to you and to your seed after you the land where you are an outsider —the whole land of Canaan—as an everlasting possession, and I will be their God.”

9God also said to Abraham, “As for you, My covenant you must keep, you and your seed after you throughout their generations.

10This is My covenant that you must keep between Me and you and your seed after you: all your males must be circumcised.

11You must be circumcised in the flesh of your foreskin, and this will become a sign of the covenant between Me and you.

12Also your eight-day-olds must be circumcised, every male, throughout your generations, including a house-born slave or a slave bought with money from any foreigner who is not of your seed.

13Your house-born slave and your purchased slave must surely be circumcised. So My covenant will be in your flesh for an everlasting covenant.

14But the uncircumcised male who is not circumcised in the flesh of his foreskin—that person will be cut off from his people; he has broken My covenant.”
