2 Corinthians 2:5-11

5 But if any has caused sorrow, he has caused sorrow, not to me, but in part (that I not press too heavily) to you all.  6 Sufficient to such a one is this punishment which was inflicted by the many;  7 so that on the contrary you should rather forgive him and comfort him, lest by any means such a one should be swallowed up with his excessive sorrow.  8 Therefore I beg you to confirm your love toward him.  9 For to this end I also wrote, that I might know the proof of you, whether you are obedient in all things.  10 Now I also forgive whomever you forgive anything. For if indeed I have forgiven anything, I have forgiven that one for your sakes in the presence of Christ,  11 that no advantage may be gained over us by Satan; for we are not ignorant of his schemes.
