2 Corinthians 12:18

I exhorted Titus, and I sent the brother with him. Did Titus take any advantage of you? walked we not in the same spirit? walked we not in the same steps? [Now let us look at the facts and see where I used such guile. My detractors admit that I myself took nothing: then I must have taken it through the agency of others. If so, by whom? Titus and the brother who accompanied him were the only agents I sent. Did Titus thus cheat you in my behalf? Did he not, on the contrary, show you the same inner spirit of self-sacrifice which I displayed? Did he not outwardly follow my plans, exhorting you not to give it to him, or send it to me, but to lay it up in your own treasury weekly as I directed? See 1 Corinthians 16:1-2. If Titus, as we have supposed, accompanied the messengers who bore Paul's first epistle to Corinth, he very naturally carried out the directions of that epistle. Who was then with him we do not know. Titus had not yet reached Corinth to undertake this work a second time as Paul directed (2 Corinthians 8:6; 2 Corinthians 8:16-17). Paul's actions were ever free from guile or covetousness-- 1 Thessalonians 2:3-5]
