Meaning
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 Exod 25:9, Num 4:12, Num 4:26, Num 4:32, 1Kgs 19:21, 1Chr 9:29, 2Chr 4:16, the King James Version); for weapons of war (1Sam 8:12, 1Chr 12:33, 1Chr 12:17, 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.
