Genesis 17:13-15

American Standard Version

¹³ He that is born in thy house, and he that is bought with thy money, must needs be circumcised: and my covenant shall be in your flesh for an everlasting covenant. ¹⁴ And the uncircumcised male who is not circumcised in the flesh of his foreskin, that soul shall be cut off from his people; he hath broken my covenant.

¹⁵ And God said unto Abraham, As for Sarai thy wife, thou shalt not call her name Sarai, but ^[a]Sarah shall her name be.
