The Urim and the Thummim in the Hebrew Bible are elements of the hoshen, the breastplate worn by the High Priest attached to the ephod, a type of apron or garment. The pair are used frequently in the Old Testament, in Exodus 28:30 and Leviticus 8:8 through God's instruction to Aaron on how to adorn his breastplate worn in the holy place; in 1 Samuel 14:41 by King Saul to determine who was at fault for breaking the army's fast; and Ezra 2 to determine whether those who claimed to be the descendants of the priests of Israel were truly of that class. The Urim and Thummim are sometimes connected by scholars with cleromancy, although it is equally likely no casting was physically done, and the participants in the ritual waited for a sign to answer a question or reveal the will of God.
