For seven days you shall make atonement for the altar [of burnt offering] and consecrate it; then the altar shall be most holy. Whatever touches the altar must be holy (set apart for God’s service).

In the breastpiece of judgment you shall put the Urim (Lights) and the Thummim (Perfections) [to be used for determining God’s will in a matter]. They shall be over Aaron’s heart whenever he goes before the Lord, and Aaron shall always carry the judgment (verdict, judicial decisions) of the sons of Israel over his heart before the Lord.
