Leviticus

¹¹Neither shall he go in where any dead body lies nor defile himself [by doing so, even] for his father or for his mother; ¹²Neither shall he go out of the sanctuary nor desecrate or make ceremonially unclean the sanctuary of his God, for the crown or consecration of the anointing oil of his God is upon him. I am the Lord. ¹³He shall take a wife in her virginity. ¹⁴A widow or a divorced woman or a woman who is polluted or profane or a harlot, these he shall not marry, but he shall take as his wife a virgin of his own people, [I Tim. 3:2-7; Tit. 1:7-9.] ¹⁵That he may not profane or dishonor his children among his people; for I the Lord do sanctify the high priest. ¹⁶And the Lord said to Moses, ¹⁷Say to Aaron, Any one of your sons in their successive generations who has any blemish, let him not come near to offer the bread of his God.
