2 Corinthians 2:5-11

But if any have caused grief, he hath not grieved me, but in part: that I may not overcharge you all. Sufficient to such a man is this punishment, which was inflicted of many. So that contrariwise ye ought rather to forgive him, and comfort him, lest perhaps such a one should be swallowed up with overmuch sorrow. Wherefore I beseech you that ye would confirm your love toward him. For to this end also did I write, that I might know the proof of you, whether ye be obedient in all things. To whom ye forgive any thing, I forgive also: for if I forgave any thing, to whom I forgave it, for your sakes forgave I it in the person of Christ; lest Satan should get an advantage of us: for we are not ignorant of his devices.
