Leviticus 21:10-15

10“He who is the kohen gadol among his brothers, upon whose head the anointing oil is poured and is consecrated to put on the garments, is not to let the hair of his head hang loose or tear his clothes,

11nor shall he go near any dead person, defiling himself, even for his father or his mother.

12He is not to go out of the Sanctuary or profane the Sanctuary of his God—for the crown of the anointing oil of his God is upon him. I am Adonai.

13“He shall take a wife in her virginity.

14A widow, or one divorced, or one who has been defiled as a prostitute, he is not to marry. He is to take a virgin from his own people as a wife,

15so as not to corrupt his offspring among his people. For I am Adonai who sanctifies him.”
