Breastplate @ (1.) That piece of ancient armour that protected the breast. This word is used figuratively in Ephesians:6:14 and Isaiah:59:17. (See ARMOUR.) (2.) An ornament covering the breast of the high priest, first mentioned in Exodus:25:7. It was made of embroidered cloth, set with four rows of precious stones, three in each row. On each stone was engraved the name of one of the twelve tribes Exodus:28:15-29Exodus:39:8-21). It was in size about ten inches square. The two upper corners were fastened to the ephod by blue ribbons. It was not to be "loosed from the ephod" Exodus:28:28). The lower corners were fastened to the girdle of the priest. As it reminded the priest of his representative character, it was called the memorial (28:29). It was also called the breastplate of judgment (28:15). (See PRIEST.)
