Thou shalt sanctify him therefore; for he offereth the bread of thy God: he shall be holy unto thee: for I the LORD, which sanctify you, am holy.
And the daughter of any priest, if she profane herself by playing the whore, she profaneth her father: she shall be burnt with fire.
And he that is the high priest among his brethren, upon whose head the anointing oil was poured, and that is consecrated to put on the garments, shall not uncover his head, nor rend his clothes;
Neither shall he go in to any dead body, nor defile himself for his father, or for his mother;
Neither shall he go out of the sanctuary, nor profane the sanctuary of his God; for the crown of the anointing oil of his God is upon him: I am the LORD.
