2 Corinthians 2:9-13

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. Furthermore, when I came to Troas to preach Christ's gospel, and a door was opened unto me of the Lord, I had no rest in my spirit, because I found not Titus my brother: but taking my leave of them, I went from thence into Macedonia.
