Genesis 17:13-15

New Life Version

¹³ He that is born in your house and he that is bought with your money must have this religious act done. So will My agreement be marked in your flesh, an agreement that lasts forever. ¹⁴ But the man who has not had this religious act done, of cutting off his piece of skin, will be cut off from his people. He has broken My agreement.”

¹⁵ Then God said to Abraham, “As for Sarai your wife, do not call her name Sarai. But Sarah will be her name.
