The breastplate of judgment. Considerable space is devoted to a detailed description of this part of the high priest’s official garb (verses 15-30), indicating its intricate form and significance. The chief purpose of the ephod was to hold the breastplate, which was attached to it after it had been put on, and formed its principal ornament. The word translated “breastplate” means “ornament.” This must have been the most striking and brilliant part of the high priest’s attire. It was called “the breastplate of judgment [decision],” because it served primarily for bearing the “Urim and the Thummim” (verse 30), whereby God was consulted and whereby He signified His will to the people. The materials of the breastplate were the same as for the ephod (verse 6).
