Leviticus 21:5-8

⁵And you° shall not shave your head for the dead with a baldness on the top; and they shall not shave their beard, neither shall they make gashes on their flesh.

⁶They shall be holy to their God, and they shall not profane the name of their God; for they offer the sacrifices of the Lord as the gifts of their God, and they shall be holy.

⁷They shall not take a woman who is a harlot and profaned, or a woman put away from her husband; for he is holy to the Lord his God.

⁸And you shall hallow him; he offers the gifts of the Lord your God: he shall be holy, for I the Lord that sanctify them am holy.
