A chief among his people shall not be defiled, to profane himself. With baldness, they shall not make baldness upon their head, and they shall not shave the extremity of their beard: and in their flesh they shall not cut incisions. They shall be holy to their God, and profane not the name of their God: for the sacrifices of Jehovah, and the bread of their God they bring: and they were holy.

And to an dead soul he shall not come, for his father, and for his mother, he shall not be defiled. And from the holy place he shall not go forth, and he shall not profane the holy place of his God; for the consecration of the anointing oil of his God is upon him I Jehovah.
