Leviticus 21:10-12

Complete Jewish Bible

¹⁰ “‘The cohen who is ranked highest among his brothers, the one on whose head the anointing oil is poured and who is consecrated to put on the garments, is not to stop grooming his hair, tear his clothes, ¹¹ go in to where any dead body is or make himself unclean, even when his father or mother dies. ¹² He may not leave the sanctuary then or profane the sanctuary of his God, because the consecration of the anointing oil of his God is on him; I am Adonai.
