Leviticus 8:6-9

6Then Moses brought Aaron and his sons forward and washed them with water. 7He put the tunic on Aaron, tied the sash around him, clothed him with the robe and put the ephod on him. He also fastened the ephod with a decorative waistband, which he tied around him. 8He placed the breastpiece on him and put the Urim and Thummim in the breastpiece. 9Then he placed the turban on Aaron’s head and set the gold plate, the sacred emblem, on the front of it, as the Lord commanded Moses.
