Exhortation (paraklhsi). Persuasive discourse, calling to one's side, for admonition, encouragement, or comfort. Not of error (ouk ek planh). This word is same as planaw, to lead astray ( 2 Timothy 3:13 ) like Latin errare. Passive idea of error here rather than deceit. That is seen in nor in guile (oude en dolwi) from delw, to catch with bait. Paul is keenly sensitive against charges against the correctness of his message and the purity of his life. Nor of uncleanness (oude ex akaqarsia). "This disclaimer, startling as it may seem, was not unneeded amidst the impurities consecrated by the religions of the day" (Lightfoot). There was no necessary connection in the popular mind between religion and morals. The ecstatic initiations in some of the popular religions were grossly sensual.
