Exodus 39:8-14

They fashioned the breastpiece—the work of a skilled craftsman. They made it like the ephod: of gold, and of blue, purple and scarlet yarn, and of finely twisted linen. It was square—a span long and a span wide—and folded double. Then they mounted four rows of precious stones on it. The first row was carnelian, chrysolite and beryl; the second row was turquoise, lapis lazuli and emerald; the third row was jacinth, agate and amethyst; the fourth row was topaz, onyx and jasper. They were mounted in gold filigree settings. There were twelve stones, one for each of the names of the sons of Israel, each engraved like a seal with the name of one of the twelve tribes.
