Exodus 28:22-25

22And thou shalt make on the breastplate chains of laced work, of wreathen work, of pure gold.

23And thou shalt make on 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 [cords] of gold in the two rings on the ends of the breastplate;

25and the two ends of the two wreathen [cords] thou shalt fasten to the two enclosures, and shalt put [them] on the shoulder-pieces of the ephod, on the front thereof.
