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.
Context
11 For behold, this same thing, that you were grieved in a godly way, what earnest care it worked in you. Yes, what defense, indignation, fear, longing, zeal, and vindication! In everything you demonstrated yourselves to be pure in the matter.
12 So although I wrote to you, I wrote not for his cause that did the wrong, nor for his cause that suffered the wrong, but that your earnest care for us might be revealed in you in the sight of God.
13 Therefore we have been comforted. In our comfort we rejoiced the more exceedingly for the joy of Titus, because his spirit has been refreshed by you all.
