Genesis 17:13-15

Holman Christian Standard Bible

¹³ a slave born in your house, as well as one purchased with money, must be circumcised. My covenant will be marked in your flesh as an everlasting covenant. ¹⁴ If any male is not circumcised in the flesh of his foreskin, that man will be cut off from his people; he has broken My covenant.”

¹⁵ God said to Abraham, “As for your wife Sarai, do not call her Sarai, for Sarah^[a] will be her name.
