Exodus 28:41

“These are the garments which they shall make: a breastpiece and an ephod and a robe and a tunic of checkered work, a turban and a sash, and they shall make holy garments for Aaron your brother and his sons, in order for him to minister as priest to Me.

“You shall gird them with sashes, Aaron and his sons, and bind caps on them, and they shall have the priesthood by a perpetual statute. So you shall ordain Aaron and his sons.

“You shall put the holy garments on Aaron and anoint him and set him apart as holy, that he may minister as a priest to Me.

“You shall not even go out from the doorway of the tent of meeting, lest you die; for the anointing oil of Yahweh is upon you.” So they did according to the word of Moses.

“And he shall bathe his body with water in a holy place and put on his clothes and come forth, and offer his burnt offering and the burnt offering of the people and make atonement for himself and for the people.

These are the names of the sons of Aaron, the anointed priests, whom he ordained to minister as priests.
