“For our exhortation was not of deceit, nor of uncleanness, nor in guile:”
King James Version (KJV)
2:3 For our exhortation - That is, our preaching. A part is put for the whole. Is not, at any time, of deceit - We preach not a lie, but the truth of God. Nor of uncleanness - With any unholy or selfish view. This expression is not always appropriated to lust, although it is sometimes emphatically applied thereto. Nor in guile - But with great plainness of speech.
1Th 2:3 For our exhortation [was] not of deceit, nor of uncleanness, nor in guile. The message they preached did not spring from deceit, or unclean lives, or guile. It was in all sincerity, and hence they were "bold" (1Th 2:2).
