Breastplate
NET Glossary: armor worn by soldiers to protect the chest, originally heavy leather (Latin coriaceus; French cuirasse) and later metal; the Romans used three types: chain mail (lorica hamata) scale armor (lorica squamata), and segmented body armor (lorica segmentata) made of narrow bands of metal
Breastplate [EBD]
(1.) That piece of ancient armour that protected the breast. This word is used figuratively in Eph. 6:14 and Isa. 59:17. (See ARMOUR.)
(2.) An ornament covering the breast of the high priest, first mentioned in Ex. 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 (Ex. 28:15-29; 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" (Ex. 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.)
