Breastplate @

(1.) That piece of ancient armour that protected the breast. This word is used figuratively in kjv@Ephesians:6:14 and kjv@Isaiah:59:17. (
See ARMOUR.)

(2.) An ornament covering the breast of the high priest, first mentioned in kjv@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 kjv@Exodus:28:15-29 kjv@Exodus: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" kjv@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.)
