Leviticus 21:5-7

Amplified Bible, Classic Edition

⁵ The priests [like the other Israelite men] shall not shave the crown of their heads or clip off the corners of their beard or make any cuttings in their flesh.

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

⁷ They shall not take a wife who is a harlot or polluted or profane or divorced, for [the priest] is holy to his God.
