2 Corinthians 2:5-11 RSV

5 But if any one has caused pain, he has caused it not to me, but in some measure--not to put it too severely--to you all.
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 Any one whom you forgive, I also forgive. What I have forgiven, if I have forgiven anything, has been for your sake in the presence of Christ,
11 to keep Satan from gaining the advantage over us; for we are not ignorant of his designs.
