Exodus 28:15-21

“You shall make a breastpiece of judgment, in skilled work. In the style of the ephod you shall make it—of gold, blue and purple and scarlet yarns, and fine twined linen shall you make it. It shall be square and doubled, a span its length and a span its breadth. You shall set in it four rows of stones. A row of sardius, topaz, and carbuncle shall be the first row; and the second row an emerald, 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 shall be set in gold filigree. There shall be twelve stones with their names according to the names of the sons of Israel. They shall be like signets, each engraved with its name, for the twelve tribes.
