2 Corinthians 8:20-24

avoiding this, that any man should blame us in the matter of this bounty which is ministered by us: for we take thought for things honorable, not only in the sight of the Lord, but also in the sight of men. And we have sent with them our brother, whom we have many times proved earnest in many things, but now much more earnest, by reason of the great confidence which he hath in you. Whether any inquire about Titus, he is my partner and my fellow-worker to you-ward; or our brethren, they are the messengers of the churches, they are the glory of Christ. Show ye therefore unto them in the face of the churches the proof of your love, and of our glorying on your behalf.
