Exodus 39:15 (KJV)

And they set in it four rows of stones: the first row was a sardius, a topaz, and a carbuncle: this was the first row.

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

And the third row, a ligure, an agate, and an amethyst.

And the fourth row, a beryl, an onyx, and a jasper: they were inclosed in ouches of gold in their inclosings.

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

And they made two ouches of gold, and two gold rings; and put the two rings in the two ends of the breastplate.

And they put the two wreathen chains of gold in the two rings on the ends of the breastplate.

And the two ends of the two wreathen chains they fastened in the two ouches, and put them on the shoulderpieces of the ephod, before it.

And they made two rings of gold, and put them on the two ends of the breastplate, upon the border of it, which was on the side of the ephod inward.

And they made two other golden rings, and put them on the two sides of the ephod underneath, toward the forepart of it, over against the other coupling thereof, above the curious girdle of the ephod.
