For even though I caused you sorrow by my letter [Note: Paul's writing of I Corinthians to correct abuses at Corinth apparently produced sorrow for their wrongdoing], I do not regret it, though I did regret it. [For] I see that my letter hurt you, though only for a short time.

See how the very fact that you were made sorry from a godly motive has produced earnestness in you! [It produced] a desire to vindicate yourselves [i.e., by making amends for your wrongdoing]; an attitude of just anger [i.e., toward the wrongdoers]; a sense of fear [i.e., a fear of God for doing wrong]; an eager desire [i.e., to do the right thing]; a zeal [i.e., to correct problems]; and an attitude of avenging [i.e., that punished the wrongdoer]. You demonstrated in everything [you did] that you were pure [i.e., innocent] in this matter. [Note: This whole description of their conduct appears to be a reference to the incident mentioned in 2:1-11].
