Exod 39:8-21

8He made the breastpiece, in skilled work, like the work of the ephod, of gold, of blue, purple, and crimson yarns, and of fine twisted linen.9It was square; the breastpiece was made double, a span in length and a span in width when doubled.10They set in it four rows of stones. A row of carnelian, chrysolite, and emerald was the first row;11and the second row, a turquoise, a sapphire, and a moonstone;12and the third row, a jacinth, an agate, and an amethyst;13and the fourth row, a beryl, an onyx, and a jasper; they were enclosed in settings of gold filigree.14There were twelve stones with names corresponding to the names of the sons of Israel; they were like signets, each engraved with its name, for the twelve tribes.15They made on the breastpiece chains of pure gold, twisted like cords;16and they made two settings of gold filigree and two gold rings, and put the two rings on the two edges of the breastpiece;17and they put the two cords of gold in the two rings at the edges of the breastpiece.18Two ends of the two cords they had attached to the two settings of filigree; in this way they attached it in front to the shoulder-pieces of the ephod.19Then they made two rings of gold, and put them at the two ends of the breastpiece, on its inside edge next to the ephod.20They made two rings of gold, and attached them in front to the lower part of the two shoulder-pieces of the ephod, at its joining above the decorated band of the ephod.21They bound the breastpiece by its rings to the rings of the ephod with a blue cord, so that it should lie on the decorated band of the ephod, and that the breastpiece should not come loose from the ephod; as the Lord had commanded Moses.
