2 Corinthians 2:5-8

If anyone has caused grief, he has not so much grieved me as he has grieved all of you to some extent—not to put it too severely. The punishment inflicted on him by the majority is sufficient. Now instead, you ought to forgive and comfort him, so that he will not be overwhelmed by excessive sorrow. I urge you, therefore, to reaffirm your love for him.
