Exodus 39:15-18

15For the breastpiece they made braided chains of pure gold, like a rope. 16They made two gold filigree settings and two gold rings, and fastened the rings to two of the corners of the breastpiece. 17They fastened the two gold chains to the rings at the corners of the breastpiece, 18and the other ends of the chains to the two settings, attaching them to the shoulder pieces of the ephod at the front.
