And thou shalt put in the breastplate of judgment the Urim and the Thummim; and they shall be upon Aaron’s heart, when he goeth in before the LORD: and Aaron shall bear the judgment of the children of Israel upon his heart before the LORD continually.
You will place the Urim and Thummim in the judgment breastplate. They will be on Aaron's chest when he goes in front of God. Aaron will carry the Israelites' judgment before the Lord all the time.
