Leviticus 21:10; Leviticus 21:12

10 'The priest who is the highest among his brothers, on whose head the anointing oil has been poured and who has been consecrated to wear the garments, shall not uncover his head nor tear his clothes;

12 nor shall he go out of the sanctuary nor profane the sanctuary of his God, for the consecration of the anointing oil of his God is on him; I am the LORD .
