2 Corinthians 7:10-12

10For grief according to 1God works repentance to salvation, never to be regretted; but the grief of the world works death.

11For, behold, this same thing, your being grieved according to 2God, how much diligence it wrought in you, but [what] excusing [of yourselves], but [what] indignation, but [what] fear, but [what] ardent desire, but [what] zeal, but [what] vengeance: in every way ye have proved yourselves to be pure in the matter.

12So then, if also I wrote to you, [it was] not for the sake of him that injured, nor for the sake of him that was injured, but for the sake of our diligent zeal for you being manifested to you before 3God.
