Agate

Easton, 1897

(Heb. shebo), a precious stone in the breast-plate of the high priest (Exodus 28:19; Exodus 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 Isaiah 54:12 and Ezekiel 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.
