⁸ And the skillfully woven sash, which is on the ephod shall be made of the same material: of gold, of blue, purple, and scarlet fabric and fine twisted linen. ⁹ You shall take two onyx stones and engrave on them the names of the [twelve] sons of Israel, ¹⁰ six of their names on one stone and the remaining six names on the other stone, arranged in the order of their births.
