2 Corinthians 2:5-11

But if any hath caused sorrow, he hath caused sorrow, not to me, but in part (that I press not too heavily) to you all. Sufficient to such a one is this punishment which was inflicted by the many; so that contrariwise ye should rather forgive him and comfort him, lest by any means such a one should be swallowed up with his overmuch sorrow. Wherefore I beseech you to confirm your love toward him. For to this end also did I write, that I might know the proof of you, whether ye are obedient in all things. But to whom ye forgive anything, I forgive also: for what I also have forgiven, if I have forgiven anything, for your sakes have I forgiven it in the presence of Christ; that no advantage may be gained over us by Satan: for we are not ignorant of his devices.
