2 Corinthians 2:5

For if I make you grieve, then who will make me glad but he who is made to grieve by me?

And I wrote this very thing to you, so that when I came, I wouldn’t have sorrow from them of whom I ought to rejoice; having confidence in you all that my joy would be shared by all of you.

For out of much affliction and anguish of heart I wrote to you with many tears, not that you should be made to grieve, but that you might know the love that I have so abundantly for you.

This punishment which was inflicted by the many is sufficient for such a one;

so that, on the contrary, you should rather forgive him and comfort him, lest by any means such a one should be swallowed up with his excessive sorrow.

Therefore I beg you to confirm your love toward him.
