Leviticus 21:8-12

⁸Thou shalt sanctify him therefore; for he offereth the bread of thy God; he shall be holy unto thee; for I the LORD, who sanctify you, am holy.

⁹And the daughter of any priest, if she profane herself by playing the harlot, she profaneth her father: she shall be burnt with fire.

¹⁰And the priest that is highest among his brethren, upon whose head the anointing oil is poured, and that is consecrated to put on the garments, shall not let the hair of his head go loose, nor rend his clothes;

¹¹neither shall he go in to any dead body, nor defile himself for his father, or for his mother;

¹²neither shall he go out of the sanctuary, nor profane the sanctuary of his God; for the consecration of the anointing oil of his God is upon him: I am the LORD.
