Exodus 39:8-21

Bezalel made the breastpiece, the work of a skillful craftsman, like the workmanship of the ephod: of gold and of blue, purple, and scarlet fabric, and fine twisted linen. It was square; they made the breastpiece folded double, a [hand’s] span long and a [hand’s] span wide when folded double. And they mounted four rows of stones on it. The first row was a row of ruby, topaz, and emerald; and the second row, a turquoise, a sapphire, and a diamond; and the third row, a jacinth, an agate, and an amethyst; and the fourth row, a beryl, an onyx, and a jasper; they were mounted in settings of gold filigree. The stones corresponded to the names of the sons of Israel; they were twelve [in all], corresponding to their names, engraved like a signet, each with its name, for the twelve tribes. And they made on the breastpiece twisted chains like cords of pure gold. They made two settings of gold filigree and two gold rings, and put the two rings on the two ends of the breastpiece. Then they put the two twisted cords of gold in the two rings on the ends of the breastpiece. They 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. They made two rings of gold and put them on the two ends of the breastpiece, on its inner edge which was next to the ephod. Furthermore, they made two [other] gold rings and attached them to the bottom of the two shoulder pieces of the ephod, at the front of it, close to the place where it is joined, above the woven sash of the ephod. They bound the breastpiece by its rings to the rings of the ephod with a blue cord, so that it would lie on the woven sash of the ephod, and so that the breastpiece would not come loose from the ephod, just as the LORD commanded Moses.
