Leviticus 4:16

“ ‘He who is the high priest among his brothers, upon whose head the anointing oil is poured, and who is consecrated to put on the garments, shall not let the hair of his head hang loose, or tear his clothes.

He shall put on the holy linen tunic. He shall have the linen trousers on his body, and shall put on the linen sash, and he shall be clothed with the linen turban. They are the holy garments. He shall bathe his body in water, and put them on.

You shall clothe them with belts, Aaron and his sons, and bind headbands on them. They shall have the priesthood by a perpetual statute. You shall consecrate Aaron and his sons.

if the anointed priest sins so as to bring guilt on the people, then let him offer for his sin which he has sinned a young bull without defect to Yahweh for a sin offering.

The anointed priest shall take some of the blood of the bull, and bring it to the Tent of Meeting.

The priest, who is anointed and who is consecrated to be priest in his father’s place, shall make the atonement, and shall put on the linen garments, even the holy garments.

Haven’t you driven out the priests of Yahweh, the sons of Aaron, and the Levites, and made priests for yourselves according to the ways of the peoples of other lands? Whoever comes to consecrate himself with a young bull and seven rams may be a priest of those who are no gods.
