Exodus 28:15-29

¹⁵“You shall make a breastpiece of judgment, the work of a skillful workman; like the work of the ephod you shall make it: of gold, of blue and purple and scarlet material and fine twisted linen you shall make it. ¹⁶It shall be square and folded double, a span in length and a span in width. ¹⁷You shall mount on it four rows of stones; the first row shall be a row of ruby, topaz and emerald; ¹⁸and the second row a turquoise, a sapphire and a diamond; ¹⁹and the third row a jacinth, an agate and an amethyst; ²⁰and the fourth row a beryl and an onyx and a jasper; they shall be set in gold filigree. ²¹The stones shall be according to the names of the sons of Israel: twelve, according to their names; they shall be like the engravings of a seal, each according to his name for the twelve tribes. ²²You shall make on the breastpiece chains of twisted cordage work in pure gold. ²³You shall make on the breastpiece two rings of gold, and shall put the two rings on the two ends of the breastpiece. ²⁴You shall put the two cords of gold on the two rings at the ends of the breastpiece. ²⁵You shall put the other two ends of the two cords on the two filigree settings, and put them on the shoulder pieces of the ephod, at the front of it. ²⁶You shall make two rings of gold and shall place them on the two ends of the breastpiece, on the edge of it, which is toward the inner side of the ephod. ²⁷You shall make two rings of gold and put them on the bottom of the two shoulder pieces of the ephod, on the front of it close to the place where it is joined, above the skillfully woven band of the ephod. ²⁸They shall bind the breastpiece by its rings to the rings of the ephod with a blue cord, so that it will be on the skillfully woven band of the ephod, and that the breastpiece will not come loose from the ephod. ²⁹Aaron shall carry the names of the sons of Israel in the breastpiece of judgment over his heart when he enters the holy place, for a memorial before the Lord continually.
