Genesis 17:12-14

Young's Literal Translation

¹² `And a son of eight days is circumcised by you; every male to your generations, born in the house, or bought with money from any son of a stranger, who is not of thy seed;

¹³ he is certainly circumcised who [is] born in thine house, or bought with thy money; and My covenant hath become in your flesh a covenant age-during;

¹⁴ and an uncircumcised one, a male, the flesh of whose foreskin is not circumcised, even that person hath been cut off from his people; My covenant he hath broken.'
