Exodus 28:19 (KJV)

And two chains of pure gold at the ends; of wreathen work shalt thou make them, and fasten the wreathen chains to the ouches.

And thou shalt make the breastplate of judgment with cunning work; after the work of the ephod thou shalt make it; of gold, of blue, and of purple, and of scarlet, and of fine twined linen, shalt thou make it.

Foursquare it shall be being doubled; a span shall be the length thereof, and a span shall be the breadth thereof.

And thou shalt set in it settings of stones, even four rows of stones: the first row shall be a sardius, a topaz, and a carbuncle: this shall be the first row.

And the second row shall be an emerald, a sapphire, and a diamond.

And the fourth row a beryl, and an onyx, and a jasper: they shall be set in gold in their inclosings.

And the stones shall be with the names of the children of Israel, twelve, according to their names, like the engravings of a signet; every one with his name shall they be according to the twelve tribes.

And thou shalt make upon the breastplate chains at the ends of wreathen work of pure gold.

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

And thou shalt put the two wreathen chains of gold in the two rings which are on the ends of the breastplate.
