Leviticus 8:7-8

⁷He put on Aaron the tunic and tied the sash around his waist, clothed him with the robe and put the ephod on him, and then he tied the ephod around him with the finely-woven waistband and bound it to him.

⁸He placed the breastpiece on him, and in the breastpiece he put the Urim and the Thummim.
