It shall be square and folded double; a span shall be its length, and a span its width.
You shall set in it settings of stones, four rows of stones: a row of ruby, topaz, and beryl shall be the first row; and the second row a turquoise, a sapphire, and an emerald; and the third row a jacinth, an agate, and an amethyst; and the fourth row a chrysolite, an onyx, and a jasper.
They shall be enclosed in gold in their settings.
