Leviticus 21:6

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

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

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

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

⁸  Thou shalt sanctify him therefore; for he offereth the bread of thy God: he shall be holy unto thee: for I the LORD, which sanctify you, am holy.
