2 Corinthians 2:5-11 (ESV)
5 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.
6 For such a one, this punishment by the majority is enough,
7 so you should rather turn to forgive and comfort him, or he may be overwhelmed by excessive sorrow.
8 So I beg you to reaffirm your love for him.
9 For this is why I wrote, that I might test you and know whether you are obedient in everything.
10 Anyone whom you forgive, I also forgive. Indeed, what I have forgiven, if I have forgiven anything, has been for your sake in the presence of Christ,
11 so that we would not be outwitted by Satan; for we are not ignorant of his designs.
