2 Corinthians 2:5-11 NKJV

5 But if anyone has caused grief, he has not grieved me, but all of you to some extent--not to be too severe.
6 This punishment which was inflicted by the majority is sufficient for such a man,
7 so that, on the contrary, you ought rather to forgive and comfort him, lest perhaps such a one be swallowed up with too much sorrow.
8 Therefore I urge you to reaffirm your love to him.
9 For to this end I also wrote, that I might put you to the test, whether you are obedient in all things.
10 Now whom you forgive anything, I also forgive. For if indeed I have forgiven anything, I have forgiven that one for your sakes in the presence of Christ,
11 lest Satan should take advantage of us; for we are not ignorant of his devices.
