Exodus 28:21-23

New King James Version

²¹ And the stones shall have the names of the sons of Israel, twelve according to their names, like the engravings of a signet, each one with its own name; they shall be according to the twelve tribes.

²² “You shall make chains for the breastplate at the end, like braided cords of pure gold. ²³ And you shall make two rings of gold for the breastplate, and put the two rings on the two ends of the breastplate.
