Exodus 28:23

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.

— Exodus 28:23 —
