Exodus 28:15-20

And thou shalt make a breastplate of judgment, the work of the skilful workman; like the work of the ephod thou shalt make it; of gold, of blue, and purple, and scarlet, and fine twined linen, shalt thou make it. Foursquare it shall be and double; a span shall be the length thereof, and a span the breadth thereof. 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; and the second row an emerald, a sapphire, and a diamond; and the third row a jacinth, an agate, and an amethyst; and the fourth row a beryl, and an onyx, and a jasper: they shall be inclosed in gold in their settings.
