Leviticus 21:11-13

New Catholic Bible

¹¹ nor shall he make himself unclean by touching any dead body, even that of his own father or mother. ¹² He shall not leave the sanctuary nor desecrate the sanctuary of his God, for the consecration of the oil of anointing of his God is on him. I am the Lord. ¹³ He shall marry a woman who is a virgin.
