Leviticus 21:4-6

Modern English Version

⁴ And he shall not make himself unclean as a husband among his people because of the dead and so defile himself.

⁵ They shall not make bald areas on their heads, nor shall they shave off the edges of their beards, nor make any cuts in their flesh. ⁶ They shall be holy unto their God, and not profane the name of their God; for they offer the offerings of the Lord made by fire, and the food of their God. Therefore they shall be holy.
