While 'conversation' in AV means manner of life, conduct, 'communication' means conversation, talk. So Col 3:6 'filthy communication' (RV 'shameful speaking') and elsewhere. The verb 'to communicate' is now used in a restricted sense, so that its occurrences in AV, where it has the general meaning of making common cause with one, may be misunderstood. Cf. the Rhemish tr of Joh 4:9 : 'For the Jewes do not communicate with the Samaritanes' (AV 'have no dealings with').
