Leviticus 21:10-15 - Rules For The High Priest
10 And the high priest among his brothers, on whose head the anointing oil was poured and who is consecrated to put on the garments, shall not uncover his head nor tear his clothes. 11 Neither shall he come near to any dead person, nor defile himself for his father nor for his mother. 12 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 on him. I am Jehovah.
13 And he shall take a wife in her virginity. 14 He shall not take a widow or a divorced woman, or profane, or a harlot, but he shall take a virgin of his own people to wife. 15 And he shall not defile his seed among his people. For I, Jehovah, do sanctify him.
