Exodus 29:8

You shall take the garments, and put on Aaron the tunic, the robe of the ephod, the ephod, and the breastplate, and clothe him with the skillfully woven band of the ephod.

You shall set the turban on his head, and put the holy crown on the turban.

Then you shall take the anointing oil, and pour it on his head, and anoint him.

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.

“You shall bring the bull before the Tent of Meeting; and Aaron and his sons shall lay their hands on the head of the bull.

You shall kill the bull before the LORD at the door of the Tent of Meeting.
