Exodus 39:14-16

Amplified Bible

¹⁴ The stones corresponded to the names of the sons of Israel; they were twelve [in all], corresponding to their names, engraved like a signet, each with its name, for the twelve tribes. ¹⁵ And they made on the breastpiece twisted chains like cords of pure gold. ¹⁶ They made two settings of gold filigree and two gold rings, and put the two rings on the two ends of the breastpiece.
