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.
