Leviticus 21:8-17

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

9And the daughter of any priest, if she profane herself by playing the whore, she profaneth her father: she shall be burnt with fire. 10And 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; 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 crown of the anointing oil of his God is upon him: I am Yhwh. 13And he shall take a wife in her virginity. 14A widow, or a divorced woman, or profane, or an harlot, these shall he not take: but he shall take a virgin of his own people to wife. 15Neither shall he profane his seed among his people: for I Yhwh do sanctify him.

16And Yhwh spake unto Moses, saying, 17Speak unto Aaron, saying, Whosoever he be of thy seed in their generations that hath any blemish, let him not approach to offer the bread of his God.1
