15 “You shall make a breastplate of judgment, the work of the skillful workman; like the work of the ephod you shall make it; of gold, of blue, and purple, and scarlet, and fine twined linen, you shall make it. 16 It shall be square and folded double; a span [1] shall be its length of it, and a span its breadth. 17 You shall set in it settings of stones, four rows of stones: a row of ruby, topaz, and beryl shall be the first row; 18 and the second row a turquoise, a sapphire [2], and an emerald; 19 and the third row a jacinth, an agate, and an amethyst; 20 and the fourth row a chrysolite, an onyx, and a jasper: they shall be enclosed in gold in their settings. 21 The stones shall be according to the names of the children of Israel, twelve, according to their names; like the engravings of a signet, everyone according to his name, they shall be for the twelve tribes. 22 You shall make on the breastplate chains like cords, of braided work of pure gold. 23 You shall make on the breastplate two rings of gold, and shall put the two rings on the two ends of the breastplate. 24 You shall put the two braided chains of gold in the two rings at the ends of the breastplate. 25 The other two ends of the two braided chains you shall put on the two settings, and put them on the shoulder straps of the ephod in its forepart. 26 You shall make two rings of gold, and you shall put them on the two ends of the breastplate, on its edge, which is toward the side of the ephod inward. 27 You shall make two rings of gold, and shall put them on the two shoulder straps of the ephod underneath, in its forepart, close by its coupling, above the skillfully woven band of the ephod. 28 They shall bind the breastplate by its rings to the rings of the ephod with a lace of blue, that it may be on the skillfully woven band of the ephod, and that the breastplate may not swing out from the ephod. 29 Aaron shall bear the names of the children of Israel in the breastplate of judgment on his heart, when he goes in to the holy place, for a memorial before Yahweh continually.

Commentary on Exodus 28:15-30
(Read Exodus 28:15-30)
The chief ornament of the high priest, was the breastplate, a rich piece of cloth, curiously worked. The name of each tribe was graven in a precious stone, fixed in the breastplate, to signify how precious, in God's sight, believers are, and how honourable. How small and poor soever the tribe was, it was as a precious stone in the breastplate of the high priest; thus are all the saints dear to Christ, however men esteem them. The high priest had the names of the tribes, both on his shoulders and on his breast, which reminds us of the power and the love with which our Lord Jesus pleads for those that are his. He not only bears them up in his arms with almighty strength, but he carries them in his bosom with tender affection. What comfort is this to us in all our addresses to God! The Urim and Thummim, by which the will of God was made known in doubtful cases, were put in this breastplate. Urim and Thummim signify light and integrity. There are many conjectures what these were; the most probable opinion seems to be, that they were the twelve precious stones in the high priest's breastplate. Now, Christ is our Oracle. By him God, in these last days, makes known himself and his mind to us, Hebrews 1:1,2; John 1:18. He is the true Light, the faithful Witness, the Truth itself, and from him we receive the Spirit of Truth, who leads into all truth.
