Leviticus 8:7-9

7Moses put a shirt on Aaron and he tied a belt round Aaron. He put a robe and an ephod on him. He tied the ephod with its special belt.

8Moses put the breastpiece on Aaron, and he put the Urim and Thummim in its pocket.

9Moses tied a piece of linen as a hat round Aaron's head. On the front of this linen he put a plate of gold with valuable stones on it. The Lord had said that Moses must do this.
