Even if I caused you sorrow by my letter, I do not regret it. Although I did regret it, I now see that my letter caused you sorrow, but only for a short time.

2 Corinthians 2:2
For if I grieve you, who is left to cheer me but those whom I have grieved?

2 Corinthians 2:3
I wrote as I did so that on my arrival I would not be saddened by those who ought to make me rejoice. I had confidence in all of you, that you would share my joy.

2 Corinthians 2:4
For through many tears I wrote you out of great distress and anguish of heart, not to grieve you but to let you know how much I love you.

2 Corinthians 7:7
and not only by his arrival, but also by the comfort he had received from you. He told us about your longing, your mourning, and your zeal for me, so that I rejoiced all the more.

2 Corinthians 7:9
And now I rejoice, not because you were made sorrowful, but because your sorrow led you to repentance. For you felt the sorrow that God had intended, and so were not harmed in any way by us.

2 Corinthians 7:12
So even though I wrote to you, it was not on account of the one who did wrong or the one who was harmed, but rather that your earnestness on our behalf would be made clear to you in the sight of God.

For though I made you sorry with a letter, I do not repent, though I did repent: for I perceive that the same letter has made you sorry, though it were but for a season.
