Sardine, Sardius (Odem, σάρδιος)

Exodus 28:17; Exodus 39:10; Revelation 21:20; Ezekiel 28:13; Revelation 4:3
One of the precious stones in the breastplate (Ex. 28:1717And thou shalt set in it settings of stones, even four rows of stones: the first row shall be a sardius, a topaz, and a carbuncle: this shall be the first row. (Exodus 28:17); Ex. 39:1010And they set in it four rows of stones: the first row was a sardius, a topaz, and a carbuncle: this was the first row. (Exodus 39:10)). It also embellished one of the foundations of the holy Jerusalem (Rev. 21:2020The fifth, sardonyx; the sixth, sardius; the seventh, chrysolite; the eighth, beryl; the ninth, a topaz; the tenth, a chrysoprasus; the eleventh, a jacinth; the twelfth, an amethyst. (Revelation 21:20)). It was one of the stones that covered the king of Tyrus—doubtless portraying Satan before his fall (Ezek. 28:1313Thou hast been in Eden the garden of God; every precious stone was thy covering, the sardius, topaz, and the diamond, the beryl, the onyx, and the jasper, the sapphire, the emerald, and the carbuncle, and gold: the workmanship of thy tabrets and of thy pipes was prepared in thee in the day that thou wast created. (Ezekiel 28:13)). In heaven One who sat upon the throne was “to look upon like a jasper and a sardine stone” (Rev. 4:33And he that sat was to look upon like a jasper and a sardine stone: and there was a rainbow round about the throne, in sight like unto an emerald. (Revelation 4:3)). It is supposed to be the sard, a superior variety of agate, of various colors, some blood-red, and others of a golden hue.
