Exodus 39:12-16

and the third row, a jacinth, an agate, and an amethyst;

and the fourth row, a beryl, an onyx, and a jasper. They were set in gold filigree settings when they were mounted.

The stones corresponded to the names of the sons of Israel; they were twelve, corresponding to their names, engraved with the engravings of a signet, each with its name for the twelve tribes.

And they made for the breastpiece chains like cords, work of twisted cords of pure gold.

They made two gold filigree settings and two gold rings, and put the two rings on the two ends of the breastpiece.
