Exodus 39:15-20

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

16And they made two ouches of 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.

19And they made two rings of gold, and put them on the two ends of the breastplate, upon the border of it, which was on the side of the ephod inward.

20And they made two other golden rings, and put them on the two sides of the ephod underneath, toward the forepart of it, over against the other coupling thereof, above the curious girdle of the ephod.
