Leviticus 8:4-8

⁴And Moses did as the Lord said, and all the people came together at the door of the Tent of meeting.

⁵And Moses said to the people, This is what the Lord has given orders to be done.

⁶Then Moses took Aaron and his sons; and after washing them with water,

⁷He put the coat on him, making it tight with its band, and then the robe, and over it the ephod, with its band of needlework to keep it in place.

⁸And he put the priest's bag on him, and in the bag he put the Urim and Thummim.
