Genesis 17:12-14

International Standard Version

¹² Generation after generation, every male among you is to be circumcised on the eighth day after his birth,^[a] including the servant born in your house or the one purchased from a foreigner, who is not of your offspring. ¹³ The servant born in your house or the one purchased with money is to be circumcised. My covenant is to remain in your flesh as an eternal covenant. ¹⁴ Any uncircumcised male who does not have the foreskin of his flesh circumcised on the eighth day^[b] after his birth^[c] is to be eliminated from his people because he has broken my covenant.”
