Description of the Breastplate of the High-Priest

The following is the description of the breastplate given in Exodus (xxviii, 15-30):

"And thou shalt make the breastplate of Judgment with cunning work; after the work of the ephod thou shalt make it; of gold, of blue, and of purple, and of scarlet, and of fine twined linen shalt thou make it.

Foursquare it shall be being doubled; a span shall be the length thereof, and a span shall be the breadth thereof.

And 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.

And the second row shall be an emerald, a sapphire, and a diamond.

And the third row a ligure, an agate, and an amethyst.

And the fourth row a beryl, and an onyx, and a jasper; they shall be set in gold in their enclosings.

And the stones shall be with the names of the children of Israel, twelve, according to their names, like the engravings of a signet; every one with his name shall they be according to the twelve tribes.

And thou shalt make upon the breastplate chains at the ends of wreathen work of pure gold.

And thou shalt make upon the breastplate two rings of gold, and shalt put the two rings on the two ends of the breastplate.

And thou shalt put the two wreathen chains of gold in the two rings which are on the ends of the breastplate.

And the other two ends of the two wreathen chains thou shalt fasten in the two ouches, and put them on the shoulder-pieces of the ephod before it.

And thou shalt make two rings of gold, and thou shalt put them upon the two ends of the breastplate in the border thereof, which is in the side of the ephod inward.

And two other rings of gold thou shalt make, and shalt put them on the two sides of the ephod underneath, toward the forepart thereof, over against the other coupling thereof, above the curious girdle of the ephod.

And they shall bind the breastplate by the rings thereof unto the rings of the ephod with a lace of blue, that it may be above the curious girdle of the ephod, and that the breastplate be not loosed from the ephod.

And Aaron shall bear the names of the children of Israel in the breastplate of judgment upon his heart, when he goeth in unto the holy place, for a memorial before the Lord continually.

And thou shalt put in the breastplate of Judgment the Urim and the Thummim; and they shall be upon Aaron's heart, when he goeth in before the Lord: and Aaron shall bear the judgment of the children of Israel upon his heart before the Lord continually."

Of the miraculous quality of the stones worn by the high-priest, the Jewish historian Josephus (37-95 A.D.) says:

"From the stones which the high-priest wore (these were sardonyxes, and I hold it superfluous to describe their nature, since it is known to all), there emanated a light, as often as God was present at the sacrifices; that which was worn on the right shoulder instead of a clasp emitting a radiance sufficient to give light even to those far away, although the stone previously lacked this splendor. And certainly this in itself merits the wonder of all those who do not, out of contempt for religion, allow themselves to be led away by a pretence of wisdom. However, I am about to relate something still more wonderful, namely, that God announced victory in battle by means of the twelve stones worn by the high-priest on his breast, set in the pectoral. For such a splendor shone from them when the army was not yet in motion, that all the people knew that God himself was present to aid them. For this reason the Greeks who reverence our solemnities, since they could not deny this, called the pectoral oracle. However, the pectoral and the onyxes ceased to emit this radiance two hundred years before the time when I write this, because God was displeased at the transgressions of the Law."

(Flavii Josephi, "De Antiq. Jud.," lib. iii, cap. viii, 9; Opera, ed. Dindorf, Parisiis, 1845, vol. i.)

This writer, who must have seen the high-priest wearing his elaborate vestments, says that the breastplate was adorned "with twelve stones of exceptional size and beauty, a decoration not easily to be acquired, on account of its enormous value. ("Ant. Jud.," lib. iii, cap. vii, 5, Flavii Josephi Opera, Basileae, 1544.) However these gems were not merely rare and costly; they also possessed wonderful and miraculous powers. Writing about 400 A.D., St. Epiphanius, Bishop of Constantia, tells of a marvellous adamas which was worn on the breast of the high-priest, who showed himself to the people, arrayed in all his gorgeous vestments, at the feasts of Pascha, Pentecost, and Tabernacles. This adamas was termed the "Declaration," because, by its appearance, it announced to the people the fate that God had in store for them. If the people were sinful and disobedient, the stone assumed a dusky hue, which portended death by disease, or else it became the color of blood, signifying that the people would be slain by the sword. If, however, the stone shone like the driven snow, then the people recognized that they had not sinned, and hastened to celebrate the festival.
