Exodus 39:15-20

15They used pure gold to make two thin chains like strings, to fix the breastpiece to the ephod

16Then they made two gold rings with beautiful gold around the edges. They fixed the rings to the two top corners of the breastpiece.

17They fixed the two gold chains to the rings on the corners of the breastpiece.

18They fixed the other ends of the two chains to the shoulder pieces of the ephod, in the front. They joined them to the gold pieces that held the onyx stones.

19They made two gold rings and they fixed them to the bottom corners of the breastpiece. They were on its inside edge, next to the ephod.

20Then they made two more gold rings. They fixed them to the bottom edge of the shoulder pieces, on the front of the ephod. They put the rings just above the ephod's belt.
