Genesis 17:11-13

21st Century King James Version

¹¹ And ye shall circumcise the flesh of your foreskin; and it shall be a token of the covenant between Me and you.

¹² And he that is eight days old shall be circumcised among you, every manchild in your generations, he that is born in the house or bought with money from any stranger who is not of thy seed.

¹³ He that is born in thy house and he that is bought with thy money must be circumcised; and My covenant shall be in your flesh for an everlasting covenant.
