Exodus 28:15-29

“You  are to make an embroidered breastpiece for making decisions.  Make it with the same workmanship as the ephod; make it of gold, of blue, purple, and scarlet yarn, and of finely spun linen. It must be square and folded double, nine inches long and nine inches wide.  Place a setting of gemstones  on it, four rows of stones: The first row should be a row of carnelian, topaz, and emerald;  the second row, a turquoise,  a lapis lazuli, and a diamond;  the third row, a jacinth,  an agate, and an amethyst; and the fourth row, a beryl, an onyx, and a jasper. They should be adorned with gold filigree in their settings. The twelve stones are to correspond to the names of Israel’s sons. Each stone must be engraved like a seal, with one of the names of the twelve tribes. “You are to make braided chains  of pure gold cord work for the breastpiece. Fashion two gold rings for the breastpiece and attach them to its two corners. Then attach the two gold cords to the two gold rings at the corners of the breastpiece. Attach the other ends of the two cords to the two filigree settings, and in this way attach them to the ephod’s shoulder pieces in the front. Make two other gold rings and put them at the two other corners of the breastpiece on the edge that is next to the inner border of the ephod. Make two more gold rings and attach them to the bottom of the ephod’s two shoulder pieces on its front, close to its seam,  and above the ephod’s woven waistband. The artisans are to tie the breastpiece from its rings to the rings of the ephod with a cord of blue yarn, so that the breastpiece is above the ephod’s waistband and does not come loose from the ephod. “Whenever he enters the sanctuary, Aaron is to carry the names of Israel’s sons over his heart on the breastpiece for decisions, as a continual reminder before the LORD.
