The vestments of the High-priest were far more rich and splendid than those of the priests. Like the latter he wore the linen drawers, but in place of the closely-fitting tunic he wore _the robe of the Ephod_, which was all blue, of woven work, without sleeves, reaching down to the feet, and drawn over the head through an opening, which was fringed with a border of woven work to prevent its rending. The skirt of this robe was set with a trimming of pomegranates of the three sacred colours, blue, crimson, and purple, with a golden bell between each pomegranate, designed to give forth a tinkling sound as he went in and out of the holy place. Immediately above this robe was _the Ephod_ itself, a short cloak consisting of two parts, one covering the back, and the other the breast and upper part of the body, wrought with colours and gold. The two halves were united on the shoulder with two onyx stones, on each of which were engraved the names of six of the tribes. It was gathered round the waist by a curious _girdle_ of fine twined linen, adorned with gold, blue, purple, and scarlet. Just above the girdle, and attached to the Ephod by rings and ribbons of blue, was the _Breast-plate_, or the _Breast-plate of Judgment_. This, like the Ephod, was of cunning work, a square of a span breadth, formed double so as to make a bag, set with 12 precious stones, in 4 rows, each engraved with the name of one of the tribes. Within the Breast-plate was the _Urim and the Thummim_ (_Light_ and _Perfection_, Ex. xxviii. 15–30). Not a word in Scripture explains the meaning of these mysterious objects, but they were certainly employed in some way now unknown for ascertaining the Divine will (comp. 1 Sam. xxviii. 6; Judg. i. 1; xx. 18; 1 Sam. xiv. 3, 18; xxiii. 9; 2 Sam. xxi. 1). Some identify them with the twelve stones inscribed with the names of the twelve tribes, and suppose that “the illumination, simultaneous or successive, of the letters” guided the High-priest to the answer; others think that within the Breast-plate was a stone or a plate of gold inscribed with the name of Jehovah, and that by means of this he was enabled to discern the Divine Voice, as it proceeded from the glories of the Shechinah. Like the other members of the order, the High-priest wore on his head a tiara, but attached to this by a blue ribbon was a gold plate, on which was engraved _Holiness to the Lord_ (Ex. xxviii. 36–39; xxxix. 30).
