Exodus 28:25

You shall make on the breastplate chains like cords, of braided work of pure gold.

You shall make on the breastplate two rings of gold, and shall put the two rings on the two ends of the breastplate.

You shall put the two braided chains of gold in the two rings at the ends of the breastplate.

You shall make two rings of gold, and you shall put them on the two ends of the breastplate, on its edge, which is toward the side of the ephod inward.

You shall make two rings of gold, and shall put them on the two shoulder straps of the ephod underneath, in its forepart, close by its coupling, above the skillfully woven band of the ephod.

They shall bind the breastplate by its rings to the rings of the ephod with a lace of blue, that it may be on the skillfully woven band of the ephod, and that the breastplate may not swing out from the ephod.
