Leviticus 21:10-12

Rules for the High Priest

21:10 “‘The high priest – who is greater than his brothers, on whose head the anointing oil is poured, who has been ordained to wear the priestly garments – must neither dishevel the hair of his head nor tear his garments. 21:11 He must not go where there is any dead person; he must not defile himself even for his father and his mother. 21:12 He must not go out from the sanctuary and must not profane the sanctuary of his God, because the dedication of the anointing oil of his God is on him. I am the Lord.
