Leviticus 21:10-12

New Catholic Bible

¹⁰ “ ‘The priest who is the most important from among his brothers, upon whose head was poured the oil of anointing, and who was consecrated to wear the garments, he is not to uncover his head or rend his garments 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.
