2 Corinthians 8:20-22

We are taking precaution so that no one will [find anything with which to] discredit us in our administration of this generous gift. For we have regard for what is honorable [and above suspicion], not only in the sight of the Lord, but also in the sight of men. We have sent with them our brother, whom we have often tested and found to be diligent in many things, but who is now even more diligent [than ever] because of his great confidence in you.
