Exodus 28:22-29

22And thou shalt make upon the breastplate chains like cords, of wreathen 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 wreathen chains of gold in the two rings at the ends of the breastplate. 25And the other two ends of the two wreathen chains thou shalt put on the two settings, and put them on the shoulder-pieces of the ephod in the forepart thereof. 26And thou shalt make two rings of gold, and thou shalt put them upon the two ends of the breastplate, upon the edge thereof, which is toward the side of the ephod inward. 27And thou shalt make two rings of gold, and shalt put them on the two shoulder-pieces of the ephod underneath, in the forepart thereof, close by the coupling thereof, above the skilfully woven band of the ephod. 28And they shall bind the breastplate by the rings thereof unto the rings of the ephod with a lace of blue, that it may be upon the skilfully 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 goeth in unto the holy place, for a memorial before Jehovah continually.
