Exodus 28:26

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.

The other two ends of the two braided chains you shall put on the two settings, and put them on the shoulder straps of the ephod in its forepart.

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.

Aaron shall bear the names of the children of Israel in the breastplate of judgment on his heart, when he goes in to the holy place, for a memorial before the LORD continually.
