Chain

A part of the insignia of office. A chain of gold was placed about Joseph's neck (Gen 41:42); and one was promised to Daniel (5:7). It is used as a symbol of sovereignty (Ezek 16:11). The breast-plate of the high-priest was fastened to the ephod by golden chains (Ex 39:17, 21).
It was used as an ornament (Prov 1:9; Song 1:10). The Midianites adorned the necks of their camels with chains (Jdg 8:21, 26).
Chains were also used as fetters wherewith prisoners were bound (Jdg 16:21; 2 Sam 3:34; 2Kg 25:7; Jer 39:7). Paul was in this manner bound to a Roman soldier (Acts 28:20; Eph 6:20; 2 Tim 1:16). Sometimes, for the sake of greater security, the prisoner was attached by two chains to two soldiers, as in the case of Peter (Acts 12:6).
