Leviticus 21:11-13

Amplified Bible

¹¹ nor shall he approach any dead person, nor defile himself [by doing so, even] for his father or for his mother; ¹² 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. ¹³ He shall take a wife in her virginity.
