Leviticus 8:7-9

He put the tunic on Aaron, tied the sash around him, clothed him with the robe, and put the ephod on him. He tied the woven band of the ephod around him and fastened it to him.

Then he put the breastpiece on him and placed the Urim and Thummim in the breastpiece.

Moses also put the turban on Aaron’s head and set the gold plate, the holy diadem, on the front of the turban, as the LORD had commanded him.
