Genesis 17:12

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.

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.

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 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 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.
