Genesis 17:14-16

Any uncircumcised male who does not have the foreskin of his flesh cut off will be cut off from his people, for he has broken my covenant.” God also said to Abraham: “Concerning your wife Sarai, you are not to call her Sarai anymore, but Sarah, ‘My Princess,’ will be her name. I will wonderfully bless her, and I will certainly give you a son through her. Yes, I will bless her greatly, and she will become a mother of nations; kings of nations will arise among her children!”
