Leviticus 8:6-9

Then Moses brought Aaron and his sons and washed them with water. He put the undertunic on Aaron, tied the sash around him, clothed him in the robe, and put the ephod (an upper vestment) on him. He tied the [skillfully woven] band of the ephod around him, with which he secured it to Aaron. Moses then put the breastpiece on Aaron, and he put in the breastpiece the Urim and the Thummim [the sacred articles the high priest used when seeking God’s will concerning the nation]. He also put the turban on Aaron’s head, and on it, in the front, Moses placed the golden plate, the holy crown, just as the LORD had commanded him.
