(Heb. tzeltzelim, from a root meaning to "tinkle"), musical instruments, consisting of two convex pieces of brass one held in each hand, which were clashed together to produce a loud clanging sound; castanets; "loud cymbals." "Highsounding cymbals" consisted of two larger plates, one held also in each hand (2 Sam. 6:5; Ps. 150:5; 1 Chr. 13:8; 15:16, 19, 28; 1 Cor. 13:1).
