NET

12 So then, even though I wrote to you, it was not on account of the one who did wrong, or on account of the one who was wronged, but to reveal to you your eagerness on our behalf before God.

Darby

12 So 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 God.

KJV

12 Wherefore, though I wrote unto you, [I did it] not for his cause that had done the wrong, nor for his cause that suffered wrong, but that our care for you in the sight of God might appear unto you.
