"a tool, instrument, weapon," is used metaphorically in Romans 6:13 of the members of the body as "instruments" (marg., "weapons"), negatively, of unrighteousness, positively, of righteousness. The metaphor is probably military (cp. ver. 23, "wages," i.e., soldiers' pay); Moule renders it "implements;" "weapons" seems to be the meaning. See ARMOR , WEAPONS.
