2 Corinthians 2:9 (KJV)

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.
