16. Foursquare it shall be and double; a span shall be the length thereof, and a span the breadth thereof.
17. And thou shalt set in it settings of stones, four rows of stones: a row of sardius, topaz, and carbuncle shall be the first row;
18. and the second row an emerald, a sapphire, and a diamond;
19. and the third row a jacinth, an agate, and an amethyst;
20. and the fourth row a beryl, and an onyx, and a jasper: they shall be inclosed in gold in their settings.
