Genesis 17:11-13

Darby Translation

¹¹ And ye shall circumcise the flesh of your foreskin; and [that] shall be a sign of the covenant between me and you.

¹² And at eight days old shall every male in your generations be circumcised among you—he who is born in the house, and he who is bought with money, any stranger who is not of thy seed.

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