Exodus 39:15-20

15And they made chains for the breastplate at the ends, like braided cords of pure gold.

16They also made two settings of gold and two gold rings, and put the two rings on the two ends of the breastplate.

17And they put the two braided chains of gold in the two rings on the ends of the breastplate.

18The two ends of the two braided chains they fastened in the two settings, and put them on the shoulder straps of the ephod in the front.

19And they made two rings of gold and put them on the two ends of the breastplate, on the edge of it, which was on the inward side of the ephod.

20They made two other gold rings and put them on the two shoulder straps, underneath the ephod toward its front, right at the seam above the intricately woven band of the ephod.
