II Corinthians 2:5-8

But if anyone has caused grief, he has not grieved me, but all of you to some extent—not to be too severe. This punishment which was inflicted by the majority is sufficient for such a man, so that, on the contrary, you ought rather to forgive and comfort him, lest perhaps such a one be swallowed up with too much sorrow. Therefore I urge you to reaffirm your love to him.
