Leviticus 21:10-15 - Rules For The High Priest

¹⁰ And he that is the high priest 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; ¹¹ neither shall he go in to any dead body, nor defile himself for his father, or 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 upon him: I am Jehovah.

¹³ And he shall take a wife in her virginity. ¹⁴ A widow, or one divorced, or a profane woman, a harlot, these shall he not take: but a virgin of his own people shall he take to wife. ¹⁵ And he shall not profane his seed among his people: for I am Jehovah who sanctifieth him.
