Agate
(Heb. shebo), a precious stone in the breast-plate of the high priest (Ex. 28:19; 39:12), the second in the third row. This may be the agate properly so called, a semi-transparent crystallized quartz, probably brought from Sheba, whence its name. In Isa. 54:12 and Ezek. 27:16, this word is the rendering of the Hebrew cadcod, which means "ruddy," and denotes a variety of minutely crystalline silica more or less in bands of different tints. This word is from the Greek name of a stone found in the river Achates in Sicily.

Chain
(1.) A part of the insignia of office. A chain of gold was placed about Joseph's neck (Gen. 41:42); and one was promised to Daniel (5:7). It is used as a symbol of sovereignty (Ezek. 16:11). The breast-plate of the high-priest was fastened to the ephod by golden chains (Ex. 39:17, 21). (2.) It was used as an ornament (Prov. 1:9; Cant. 1:10). The Midianites adorned the necks of their camels with chains (Judg. 8:21, 26). (3.) Chains were also used as fetters wherewith prisoners were bound (Judg. 16:21; 2 Sam. 3:34; 2 Kings 25:7; Jer. 39:7). Paul was in this manner bound to a Roman soldier (Acts 28:20; Eph. 6:20; 2 Tim. 1:16). Sometimes, for the sake of greater security, the prisoner was attached by two chains to two soldiers, as in the case of Peter (Acts 12:6).

Beryl
The rendering in the Authorized Version of the Hebrew word tarshish, a precious stone; probably so called as being brought from Tarshish. It was one of the stones on the breastplate of the high priest (Ex. 28:20; R.V. marg., "chalcedony;" 39:13). The colour of the wheels in Ezekiel's vision was as the colour of a beryl stone (1:16; 10:9; R.V., "stone of Tarshish"). It is mentioned in Cant. 5:14; Dan. 10:6; Rev. 21:20. In Ezek. 28:13 the LXX. render the word by "chrysolite," which the Jewish historian Josephus regards as its proper translation. This also is the rendering given in the Authorized Version in the margin. That was a gold-coloured gem, the topaz of ancient authors.
