Genesis 17:13-15

New King James Version

¹³ He who is born in your house and he who is bought with your money must be circumcised, and My covenant shall be in your flesh for an everlasting covenant. ¹⁴ And the uncircumcised male child, who is not circumcised in the flesh of his foreskin, that person ^(A)shall be cut off from his people; he has broken My covenant.”

¹⁵ Then God said to Abraham, “As for Sarai your wife, you shall not call her name Sarai, but ^[a]Sarah shall be her name.
