Exodus 28:17-19

(17-19) Set in it settings of stones... There is always considerable difficulty in identifying ancient with modern gems, the etymologies of the words being frequently uncertain, the names (where they have survived) having sometimes changed their meaning, and the opinions of early commentators, who might seem to speak with some authority, being discrepant. In the present case, scarcely one of the twelve stones can be said to be determined with certainty. 1. The ôdem, identified by the LXX. and the Vulg. With the “sard,” has been regarded as the ruby, the carbuncle, and the carnelian. Etymologically the word means “red,” or “the red stone.” The ruby is certainly wrong, since ancient engravers could not cut it. Either “sard” or “carnelian” is probably intended, both being common in Egypt. 2. The pitdah is certainly not the topaz, which could no more be cut than the ruby. If the word is derived, as supposed, from a root meaning “pale,” the chrysolite, which resembles a pale topaz, but is far softer, may be meant. 3. The bârěketh is rendered smaragdus, “emerald,” by the LXX. and Vulg.; but neither could the emerald be cut by the ancient engravers. The word means “brightly flashing,” which tells us next to nothing. “Beryl” and “a kind of corundum” have been suggested; but neither is particularly sparkling. 4. The nôphek, translated ἃυθραξ by the LXX. and Josehus, may well be the “carbuncle,” as is now generally supposed. It cannot, any more than the ôdem, be the ruby. 5. The sappir one might have supposed by its name to be certainly the “sapphire;” but this, again, is a gem which ancient engravers could not cut. It would seem that here we have one of the cases where the name has been transferred from one stone to another, the modern “lapis lazuli” being the gem which was called “sapphire” by the ancients. 6. The yahălôm is certainly not the “diamond,” which is the hardest of all gems. The LXX. and Vulg. translate by “jasper” (ἴασπις, jaspis); but this seems really to have been the twelfth stone. Other renderings are mere conjectures, and the yahălôm must be regarded as unknown. 7. The leshem, rendered “ligure” by the LXX., the Vulgate, Josephus, and our translators, is probably the stone known to the ancients as lapis ligurius, but what that stone was is a matter of great uncertainty. It has been regarded as amber, as jacinth, and as tourmaline; but amber does not admit of engraving, while jacinth and tourmaline are pure conjectures. This stone, then, must also be regarded as unknown. 8. The shevo, rendered achates, “agate,” by the LXX. and the Vulg., is generally allowed to have been that stone, which was well known to the ancients, and widely used for engraving. 9. The akhlâmâh was regarded as the amethyst by the LXX., the Vulgate, and Josephus; but it has been suggested that it may have been “malachite” (Knobel); and there is no disproving the suggestion. Still the amethyst, which is easily engraved, and was well known in Egypt, should find a place in the present list, and may well have been intended by the akhlâmâh. 10. The tarshish, by its name, should be a stone brought from Tarshish, which is either Tarsus or Tartessus. Some suppose it to have been the beryl, some the chrysolite, others the turquoise. There are really no sufficient grounds for identifying it with any known gem. 11. The shôham has been already discussed (see Note on Exodus 28:9), and identified with the onyx, or the sardonyx. 12. The yâsh’peh should, by its name, be the “jasper,” which was one of the stones most used in Egypt, and which could scarcely have been absent from the present list. The LXX., however, translate “onyx,” Josephus and the Vulgate “beryl;” so that here again there is uncertainty. The views of the present writer may be best presented to the reader by means of a table: —
