|chain (chān) Pronunciation Key
A group of atoms, often of the same element, bound together in a line, branched line, or ring to form a molecule. ◇ In a straight chain, each of the constituent atoms is attached to other single atoms, not to groups of atoms. ◇ In a branched chain, side groups are attached to the chain. ◇ In a closed chain, the atoms are arranged in the shape of a ring.
(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).
