The third distinctive ornament of the Jewish high priest. In material and ornamentation like the Ephod, its most precious ornament consisted of twelve jewels set in four rows, each one being the name of one of the tribes. It was about 10 inches square and was constructed like a Benediction burse, containing the Urim and Thummim. It was fastened with gold chains to the onyx stones on the shoulders and with blue ribbons to the Ephod.
