2 Corinthians 8:20-24

20We want to avoid any criticism of the way we administer this generous gift. 21For we are taking great care to do what is right, not only in the eyes of the Lord, but also in the eyes of men.

22And we are sending along with them our brother who has proven his earnestness to us many times and in many ways, and now even more so by his great confidence in you. 23As for Titus, he is my partner and fellow worker among you. As for our brothers, they are messengers1 of the churches, the glory of Christ. 24In full view of the churches, then, show these men the proof of your love and the reason for our boasting about you.
