Genesis 17:9–12

Then God said to Abraham, “As for you, you must keep my covenant, you and your descendants after you for the generations to come. This is my covenant with you and your descendants after you, the covenant you are to keep: Every male among you shall be circumcised. You are to undergo circumcision, and it will be the sign of the covenant between me and you. For the generations to come every male among you who is eight days old must be circumcised, including those born in your household or bought with money from a foreigner—those who are not your offspring.

God also said to Abraham, “As for you, you and your offspring after you throughout their generations are to keep my covenant. This is my covenant between me and you and your offspring after you, which you are to keep: Every one of your males must be circumcised. You must circumcise the flesh of your foreskin to serve as a sign of the covenant between me and you. Throughout your generations, every male among you is to be circumcised at eight days old—every male born in your household or purchased from any foreigner and not your offspring.

Then God said to Abraham, “Your responsibility is to obey the terms of the covenant. You and all your descendants have this continual responsibility. This is the covenant that you and your descendants must keep: Each male among you must be circumcised. You must cut off the flesh of your foreskin as a sign of the covenant between me and you. From generation to generation, every male child must be circumcised on the eighth day after his birth. This applies not only to members of your family but also to the servants born in your household and the foreign-born servants whom you have purchased.

And God said to Abraham, “Now as for you, you must keep my covenant, you and your offspring after you, throughout their generations. This is my covenant which you shall keep, between me and you, and also with your offspring after you: Every male among you shall be circumcised. And you shall circumcise the flesh of your foreskin, and it shall be a sign of the covenant between me and you. And at eight days of age you shall yourselves circumcise every male belonging to your generations and the servant born in your house and the one bought from any foreigner who is not from your offspring.

And God said unto Abraham, Thou shalt keep my covenant therefore, thou, and thy seed after thee in their generations. This is my covenant, which ye shall keep, between me and you and thy seed after thee; Every man child among you shall be circumcised. And ye shall circumcise the flesh of your foreskin; and it shall be a token of the covenant betwixt me and you. And he that is eight days old shall be circumcised among you, every man child in your generations, he that is born in the house, or bought with money of any stranger, which is not of thy seed.
