The Greek verb doloo (G1389) means to falsify, to corrupt by adulteration, or to handle craftily and deceitfully. It derives from dolos (bait/deceit) and describes the deliberate distortion of something pure.
Doloo appears in 2 Corinthians 4:2 as a central statement of Paul's apostolic integrity: 'We do not use deception (doloo), nor do we distort the word of God.' Some handlers of the gospel corrupt (doloo) it like merchants adulterating wine with water for profit. Paul's response is transparent proclamation. Doloo of God's Word is among the gravest sins a teacher can commit.
