2 Corinthians 7:5-8

5For even when we came into Macedonia, our bodies had no rest, but we were afflicted at every turn—fighting without and fear within. 6But God, who comforts the downcast, comforted us by the coming of Titus, 7and not only by his coming but also by the comfort with which he was comforted by you, as he told us of your longing, your mourning, your zeal for me, so that I rejoiced still more. 8For even if I made you grieve with my letter, I do not regret it—though I did regret it, for I see that that letter grieved you, though only for a while.
