Exodus 28:21 KJV

19And the third row a ligure, an agate, and an amethyst.

20And the fourth row a beryl, and an onyx, and a jasper: they shall be set in gold in their inclosings.

21And 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.

22And thou shalt make upon the breastplate chains at the ends of wreathen work of pure gold.

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