2 Corinthians 2:5-8

2:5 But 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. 2:6 This punishment on such an individual by the majority is enough for him, 2:7 so 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. 2:8 Therefore I urge you to reaffirm your love for him.
