"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.
And the stones shall be according to the names of the children of Israel, twelve, according to their names; like the engravings of a signet, every one according to his name, they shall be for the twelve tribes.
And thou shalt make upon the breastplate chains like cords, of wreathen work of pure gold." Ex. 28:15 - 22
