9 Next take two onyx stones and engrave the names of the sons of Israel on them in the order of their birth, 10 six names on one stone and the remaining six on the other. 11 Engrave the names of the sons of Israel on the two stones the way a jeweler engraves a seal. Then mount the stones in settings of filigreed gold. 12 Fasten the two stones on the shoulder pieces of the Ephod - they are memorial stones for the Israelites. Aaron will wear these names on his shoulders as a memorial before God. 13 Make the settings of gold filigree. 14 Make two chains of pure gold and braid them like cords, then attach the corded chains to the settings. The Breastpiece
15 "Now make a Breastpiece of Judgment, using skilled craftsmen, the same as with the Ephod. Use gold; blue, purple, and scarlet material; and fine twisted linen. 16 Make it nine inches square and folded double. 17 Mount four rows of precious gemstones on it. First row: carnelian, topaz, emerald. 18 Second row: ruby, sapphire, crystal. 19 Third row: jacinth, agate, amethyst. 20 Fourth row: beryl, onyx, jasper. 21 The twelve stones correspond to the names of the Israelites, with twelve names engraved, one on each, as on a seal for the twelve tribes. 22 "Then make braided chains of pure gold for the Breastpiece, like cords. 23 Make two rings of gold for the Breastpiece and fasten them to the two ends. 24 Fasten the two golden cords to the rings at the ends of the Breastpiece. 25 Then fasten the other ends of the two cords to the two settings of filigree, attaching them to the shoulder pieces of the Ephod in front. 26 Then make two rings of gold and fasten them to the two ends of the Breastpiece on its inside edge facing the Ephod. 27 Then make two more rings of gold and fasten them in the front of the Ephod to the lower part of the two shoulder pieces, near the seam above the decorated band. 28 Fasten the Breastpiece in place by running a cord of blue through its rings to the rings of the Ephod so that it rests secure on the decorated band of the Ephod and won't come loose. 29 "Aaron will regularly carry the names of the sons of Israel on the Breastpiece of Judgment over his heart as he enters the Sanctuary into the presence of God for remembrance.

This richly-wrought ephod was the outmost garment of the high priest; plain linen ephods were worn by the inferior priests. It was a short coat without sleeves, fastened close to the body with a girdle. The shoulder-pieces were buttoned together with precious stones set in gold, one on each shoulder, on which were engraven the names of the children of Israel. Thus Christ, our High Priest, presents his people before the Lord for a memorial. As Christ's coat had no seam, but was woven from the top throughout, so it was with the ephod. The golden bells on this ephod, by their preciousness and pleasant sound, well represent the good profession that the saints make, and the pomegranates the fruit they bring forth.
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.
