Exodus 28:17-28

17And thou shalt set in it settings of stones — four rows of stones: [one] row, a sardoin, a topaz, and an emerald — the first row;

18and the second row, a carbuncle, a sapphire, and a diamond;

19and the third row, an opal, an agate, and an amethyst;

20and the fourth row, a chrysolite, and an onyx, and a jasper; enclosed in gold shall they be in their settings.

21And the stones shall be according to the names of the children of Israel, twelve, according to their names, engraved as a seal: every one according to his name shall they be for the twelve tribes.

22And thou shalt make on the breastplate chains of laced work, of wreathen work, of pure gold.

23And thou shalt make on the breastplate two rings of gold, and shalt put the two rings on the two ends of the breastplate.

24And thou shalt put the two wreathen [cords] of gold in the two rings on the ends of the breastplate;

25and the two ends of the two wreathen [cords] thou shalt fasten to the two enclosures, and shalt put [them] on the shoulder-pieces of the ephod, on the front thereof.

26And thou shalt make two rings of gold, and shalt put them on the two ends of the breastplate, on the border thereof, which faceth the ephod inwards.

27And two rings of gold shalt thou make, and shalt put them upon the two shoulder-pieces of the ephod underneath, to the front thereof just by the coupling thereof, above the girdle of the ephod.

28And they shall bind the breastplate with its rings to the rings of the ephod with a lace of blue, that it may be above the girdle of the ephod, and that the breastplate be not loosed from the ephod.
