You are also to make a breastpiece of judgment with the same workmanship as the ephod. Construct it with gold, with blue, purple, and scarlet yarn, and with finely spun linen. It must be square when folded over double, a span long and a span wide. And mount on it a setting of gemstones, four rows of stones: In the first row there shall be a ruby, a topaz, and an emerald; in the second row a turquoise, a sapphire, and a diamond; in the third row a jacinth, an agate, and an amethyst; and in the fourth row a beryl, an onyx, and a jasper. Mount these stones in gold filigree settings. The twelve stones are to correspond to the names of the sons of Israel, each engraved like a seal with the name of one of the twelve tribes.
