Urim and Thummim Recreation comes in a plastic bag with information about them. They are designed to be used with the recreation of Aaron's Breastplate. They are sold separately except in the complete High Priest set. They are designed for demonstration purposes, so they can be handled. Stones are about 1 1/2 inches long. History: Urim and Thummim Exodus 28:30 “And thou shalt put in the breastplate of judgment the Urim and Thummim; they shall be upon Aaron’s heart when he goeth in before the Lord.” The Urim and Thummim was God’s way of answering His people. Urim (אורים) means “light” and Thummim (תמים) probably means “darkness/truth.” Possible recreation; Urim, white stone means no answer, and Thummim black stone means yes.
