St. Jerome (346?–420 A.D.), in his commentary on Isaiah (liv, 11, 12), alludes to the verses of Ezekiel describing the glories of the King of Tyre and the precious stones with which he was adorned. Evidently Jerome believed that this passage was to be taken symbolically, for he asks:

Who could have so little judgment and intelligence as to think that any Prince of Tyre whatever should be set in the Paradise of God, and have his place among the Cherubim, or could fancy that he dwelt with the glowing stones, which we should without doubt understand as the angels and the celestial virtues.[[512]]

It would be both curious and interesting if we could trace a connection between the significance of the names of the Hebrew tribes and those of the breastplate gems assigned to the tribes. In ancient times names were much more significant than they are to-day, and the tribal names in particular possessed for the Hebrews a symbolic meaning, but this does not appear to have induced any marked tendency to connect the colors or the symbolic meanings of the different stones with the fame, or with the characteristics or fortunes of the several tribes. On the other hand, the foundation stones, as symbols of the Apostles, became a favorite theme with the early Christian writers. Possibly the neglect of ancient Hebrew writers to perform a similar task in connection with the breastplate stones might still be made good, even at this late date, and an effort in this direction might result in giving a wider range to the symbolic value of certain well-known gems.

The name Reuben signifies “Behold a Son,” and this has been given a Messianic meaning by some commentators. In Jacob’s enigmatic blessing, “excellency of dignity” and “excellency of power” are attributed to Reuben, but this birthright is taken from him because of a heinous sin he has committed. Still we might see in the carnelian, the gem of Reuben, a symbol of “dignity” and “power.”

Simeon has been variously rendered “Hearing” or “Hearkener.” The blessing accuses him of an act of cruelty in which he was aided by his brother Levi. To the peridot, or chrysolite, dedicated to Simeon, could be appropriately assigned the meaning “good tidings.”

The priestly functions of the tribe of Levi are expressed by the name itself which means “attached” or “joined,” that is, to the altar. Hence in the emerald we should see the symbol of “dedication” or “ministration,” in addition to its other and better known meanings, such as “hope,” “faith,” and “resurrection.”

For the tribe of Judah we have the ruby, and here the meaning of the name, “praised,” fits in well with the dignity of the rare and glowing ruby. This noble gem has always been a favorite adornment for royal crowns and from Judah sprang the royalty of Israel. The blessing given to this tribe declares that “the sceptre shall not depart from Judah, nor a lawgiver from between his feet, until Shiloh come.” This is often taken to signify the consummation of the Kingdom of Israel in the Kingdom of Heaven.

Issachar, signifying “reward,” or “the rewarded,” suggests as symbolic meanings of the tribal stone lapis lazuli, “success” and “fruition.” This stone, the sapphire of the ancients, was typical of heaven, probably owing to the appearance of the specimens most highly valued in olden times, those in which a number of golden spots are scattered over the blue surface of the stone, which thus figure both the blue of heaven and the hosts of the stars.

The tribal name Zebulon signifies “exaltation,” and to this tribe is assigned a dwelling-place by the sea bordering on the domains of the rich Phenician seaport, Sidon. We could thus see in the gem of Zebulon, the onyx, a symbol of dominion and authority. This could serve to offset some of the old superstitions regarding the onyx, which was sometimes charged with bringing discord and dissension.

Of the tribe Joseph, we are told that it was to be increased, and this meaning is contained in the name itself, which is rendered: “May God add.” To Joseph were promised “blessings of heaven above,” and “blessings of the deep that lieth under.” The sapphire, probably the tribal stone of Joseph, was known in ancient times by the name hyacinth and was a stone of good omen, bringing increase of health and wealth; therefore its significance as a tribal gem does not differ essentially from the traditional one.
