Leviticus 21:3-7

³and sister, a virgin, that is not wedded to man;

⁴but neither he shall be defouled in the prince of his people.

⁵Priests shall not shave their head, neither beard, neither they shall make carvings in their fleshes;

⁶they shall be holy to their God, and they shall not defoul his name; for they offer incense of the Lord, and the loaves of their God, and therefore they shall be holy.

⁷A priest shall not wed a wife a corrupt woman, and a foul whore, neither he shall wed her that is forsaken of the husband, for he is hallowed to his God,
