Instrument
in'-stroo-ment (keli; in Greek plural hopla, Ro 6:13): The word in the Old Testament is used for utensils for service, chiefly in connection with the sanctuary (compare Ex 25:9; Nu 4:12,26,32; 1Ki 19:21; 1Ch 9:29; 2Ch 4:16, the King James Version); for weapons of war (1Sa 8:12; 1Ch 12:33,17, etc.); notably for musical instruments. See MUSIC. The members of the body are described by Paul (Ro 6:13) as "instruments" to be used in the service of righteousness, as before they were in the service of unrighteousness.
