2 Corinthians 2:5-8

5But if anyone has caused sadness, he has not saddened me alone, but to some extent (not to exaggerate) he has saddened all of you as well.

6This punishment on such an individual by the majority is enough for him,

7so that now instead you should rather forgive and comfort him. This will keep him from being overwhelmed by excessive grief to the point of despair.

8Therefore I urge you to reaffirm your love for him.
