(1.) 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).

(2.) It was used as an ornament (Prov. 1:9; Cant. 1:10). The
Midianites adorned the necks of their camels with chains (Judg.
8:21, 26).

(3.) Chains were also used as fetters wherewith prisoners were
bound (Judg. 16:21; 2 Sam. 3:34; 2 Kings 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).
