Exodus 39:8-21

⁸ He 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. ⁹ It was square; the breastpiece was made double, a span in length and a span in width when doubled. ¹⁰ They set in it four rows of stones. A row of carnelian, chrysolite, and emerald was the first row; ¹¹ and the second row, a turquoise, a sapphire, and a moonstone; ¹² and the third row, a jacinth, an agate, and an amethyst; ¹³ and the fourth row, a beryl, an onyx, and a jasper; they were enclosed in settings of gold filigree. ¹⁴ There 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. ¹⁵ They made on the breastpiece chains of pure gold, twisted like cords; ¹⁶ and they made two settings of gold filigree and two gold rings, and put the two rings on the two edges of the breastpiece; ¹⁷ and they put the two cords of gold in the two rings at the edges of the breastpiece. ¹⁸ Two 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. ¹⁹ Then they made two rings of gold, and put them at the two ends of the breastpiece, on its inside edge next to the ephod. ²⁰ They 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. ²¹ They 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.
