Exodus 39:8-14

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.
