10The priest who is highest among his brothers, who has had the anointing oil poured on his head and has been ordained to wear the priestly garments, must not let his hair hang loose or tear his garments.
11He must not go near any dead body; he must not defile himself, even for his father or mother.
12He must not leave or desecrate the sanctuary of his God, for the consecration of the anointing oil of his God is on him. I am the LORD.
— Leviticus 21:10-12
