17. And thou shalt set in it settings of stones--four rows of stones: one row, a sardoin, a topaz, and an emerald--the first row;
18. and the second row, a carbuncle, a sapphire, and a diamond;
19. and the third row, an opal, an agate, and an amethyst;
20. and the fourth row, a chrysolite, and an onyx, and a jasper; enclosed in gold shall they be in their settings.
