Leviticus 21:4-6

BRG Bible

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.
