Exodus 28:21-23

King James Version

²¹ 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.

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

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