Exodus 39:15-20

15And they made on the breastpiece twisted chains like cords, of pure gold.

16And they made two settings of gold filigree and two gold rings, and put the two rings on the two edges of the breastpiece.

17And they put the two cords of gold in the two rings at the edges of the breastpiece.

18They attached the two ends of the two cords to the two settings of filigree. Thus they attached it in front to the shoulder pieces of the ephod.

19Then they made two rings of gold, and put them at the two ends of the breastpiece, on its inside edge next to the ephod.

20And they made two rings of gold, and attached them in front to the lower part of the two shoulder pieces of the ephod, at its seam above the skillfully woven band of the ephod.
