Leviticus 8:7-9

7Then he put the tunic on Aaron, wrapped the sash around him, and clothed him with the robe. Next he put the ephod on him and placed on him the decorated band of the ephod, and fastened the ephod closely to him with the band.

8He then set the breastpiece on him and put the Urim and Thummim into the breastpiece.

9Finally, he set the turban on his head and attached the gold plate, the holy diadem, to the front of the turban just as the Lord had commanded Moses.
