Exodus 28:22-29

22And thou shalt make upon the breastplate chains at the ends of braided work of pure gold. 23And thou shalt make upon the breastplate two rings of gold, and shalt put the two rings on the two ends of the breastplate. 24And thou shalt put the two braided chains of gold in the two rings which are on the ends of the breastplate. 25And the other two ends of the two braided chains thou shalt fasten in the two settings, and put them on the shoulderpieces of the ephod before it. 26And thou shalt make two rings of gold, and thou shalt put them upon the two ends of the breastplate in its border, which is in the side of the ephod inward. 27And two other rings of gold thou shalt make, and shalt put them on the two sides of the ephod underneath, toward the forepart of it, opposite its other coupling, above the beautifully woven band of the ephod. 28And they shall bind the breastplate by its rings to the rings of the ephod with a lace of blue, that it may be above the beautifully woven band of the ephod, and that the breastplate be not loosed from the ephod. 29And Aaron shall bear the names of the children of Israel in the breastplate of judgment upon his heart, when he entereth into the holy place, for a memorial before the LORD continually.
