Leviticus 21:4-7

⁴He shall not defile himself, being a chief man among his people, to profane himself.

⁵They shall not make baldness upon their head, neither shall they shave off the corner of their beard, nor make any cuttings in their flesh.

⁶They shall be holy unto their God, and not profane the name of their God; for the offerings of Jehovah made by fire, the bread of their God, they do offer: therefore they shall be holy.

⁷They shall not take a woman that is a harlot, or profane; neither shall they take a woman put away from her husband: for he is holy unto his God.
