22 And thou shalt make upon the breastplate chains at the ends of wreathen work of pure gold.
23 And thou shalt make upon the breastplate two rings of gold, and shalt put the two rings on the two ends of the breastplate.
24 And thou shalt put the two wreathen chains of gold in the two rings which are on the ends of the breastplate.
25 And the other two ends of the two wreathen chains thou shalt fasten in the two ouches, and put them on the shoulderpieces of the ephod before it.
The breastplate would hang from two golden chains, one on each side. The other ends of the chains would be secured to the two shoulder pieces that the onyx stones were held in. Yesterday I spoke of the broad sense of duty that the priest had for each of the twelve tribes (represented by the onyx stones on the shoulders), in addition to the specific love that would be required for each one (represented by the individual stones on the breastplate).
In today’s verses, those two concepts are literally linked together. The love and the duty are fastened together. The duty is borne because of the love, and the love is borne out in the performance of the duty.
