Leviticus 21:10-14

‘The priest who is highest among his brothers, on whose head the anointing oil has been poured and who has been consecrated to wear the garments, shall not uncover his head nor tear his clothes;

nor shall he approach any dead person, nor defile himself even for his father or his mother;

nor shall he leave the sanctuary nor profane 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.

A widow, or a divorced woman, or one who is profaned by prostitution, these he shall not take; but rather he is to marry a virgin of his own people,
