They were excluded from priestly privileges or responsibilities until the high priest received divine guidance through the Urim and Thummim to know God's will (see Exodus 28:30; Numbers 27:21). Although using the Urim and Thummim was like throwing dice or drawing straws, when done by the priest, the result was a divine decision, not random chance.
