Exodus 28:22-25

22And thou shalt make upon the breastplate chains like cords, of wreathen work of pure gold.

23And thou shalt make upon the breastplate two rings of gold, and shalt put the two rings on the two ends of the breastplate.

24And thou shalt put the two wreathen chains of gold on the two rings at the ends of the breastplate.

25And the other two ends of the two wreathen chains thou shalt put on the two ouches, and put them on the shoulderpieces of the ephod, in the forepart thereof.
