15 And thou shalt make the breastplate of judgment of artistic work, like the work of the ephod thou shalt make it; of gold, blue, and purple, and scarlet, and twined byssus shalt thou make it. 16 Square shall it be, doubled; a span the length thereof, and a span the breadth thereof. 17 And thou shalt set in it settings of stones—four rows of stones: [one] row, a sardoin, a topaz, and an emerald—the first row; 18 and the second row, a carbuncle, a sapphire, and a diamond; 19 and the third row, an opal, an agate, and an amethyst; 20 and the fourth row, a chrysolite, and an onyx, and a jasper; enclosed in gold shall they be in their settings. 21 And the stones shall be according to the names of the children of Israel, twelve, according to their names, engraved as a seal: every one according to his name shall they be for the twelve tribes. 22 And thou shalt make on the breastplate chains of laced work, of wreathen work, of pure gold. 23 And thou shalt make on the breastplate two rings of gold, and shalt put the two rings on the two ends of the breastplate. 24 And thou shalt put the two wreathen [cords] of gold in the two rings on the ends of the breastplate; 25 and the two ends of the two wreathen [cords] thou shalt fasten to the two enclosures, and shalt put [them] on the shoulder-pieces of the ephod, on the front thereof. 26 And thou shalt make two rings of gold, and shalt put them on the two ends of the breastplate, on the border thereof, which faceth the ephod inwards. 27 And two rings of gold shalt thou make, and shalt put them upon the two shoulder-pieces of the ephod underneath, to the front thereof just by the coupling thereof, above the girdle of the ephod. 28 And they shall bind the breastplate with its rings to the rings of the ephod with a lace of blue, that it may be above the girdle of the ephod, and that the breastplate be not loosed from the ephod. 29 And Aaron shall bear the names of the children of Israel in the breastplate of judgment on his heart, when he goes in to the sanctuary, for a memorial before Jehovah 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.
