Exodus 39:16

14The stones were according to the names of the children of Israel, twelve, according to their names; like the engravings of a signet, everyone according to his name, for the twelve tribes.

15They made on the breastplate chains like cords, of braided work of pure gold.

16They made two settings of gold, and two gold rings, and put the two rings on the two ends of the breastplate.

17They put the two braided chains of gold in the two rings at the ends of the breastplate.

18The other two ends of the two braided chains they put on the two settings, and put them on the shoulder straps of the ephod, in its front.
