Exodus 39:16LXX

14And the stones according to the names of the children of Israel, twelve, according to their names, the engravings of a signet, every one with his name, according to the twelve tribes.

15And they made upon the breastplate chains at the ends, wreathen work pure gold.

16And they made two ouches gold, and two gold rings; and put the two rings in the two ends of the breastplate.

17And they put the two wreathen chains of gold in the two rings on the ends of the breastplate.

18And the two ends of the two wreathen chains they fastened in the two ouches, and put them on the shoulderpieces of the ephod, before it.
