2 Corinthians 2:5-8, 10
Now if anyone has caused pain, he has caused it not to me, but in some measure — not to put it too severely – to all of you. For such a one, this punishment by the majority is enough, so you should rather turn to forgive and comfort him, or he may be overwhelmed by excessive sorrow. So I beg you to reaffirm your love for him … Anyone whom you forgive, I also forgive.
