Leviticus 8:7-9

7He put the official tunic on Aaron and tied the sash around his waist. He dressed him in the robe, placed the ephod on him, and attached the ephod securely with its decorative sash.

8Then Moses placed the chestpiece on Aaron and put the Urim and the Thummim inside it.

9He placed the turban on Aaron’s head and attached the gold medallion—the badge of holiness—to the front of the turban, just as the Lord had commanded him.
