Leviticus 21:7-14

They shall not take [as a wife] a woman who is a prostitute, nor a woman who is divorced from her husband; for the priest is holy to his God. You shall consecrate him, therefore, for he offers the food of your God; he shall be holy to you; for I the LORD, who sanctifies you, am holy. The daughter of any priest who profanes herself by prostitution profanes her father; she shall be burned in fire. [Josh 7:15, 25] ‘But he who is the high priest among his brothers, on whose head the anointing oil has been poured and who has been consecrated to wear the [sacred] garments, shall not uncover his head nor tear his clothes [in mourning], nor shall he approach any dead person, nor defile himself [by doing so, even] for his father or for his mother; nor shall he go out of the sanctuary nor profane (make ceremonially unclean) the sanctuary of his God, for the consecration of the anointing oil of his God is on him; I am the LORD. He shall take a wife in her virginity. He may not marry a widow or a divorced woman or one who is profaned by prostitution, but he is to marry a virgin from his own people, [1 Tim 3:2-7; Titus 1:7-9]
