Leviticus 21:3-5

Modern English Version

³ and his virgin sister (who is near him because she has not had a husband), for her he may be made unclean. 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.
