KJV: And we have sent with them our brother, whom we have oftentimes proved diligent in many things, but now much more diligent, upon the great confidence which I have in you.
NASB: We have sent with them our brother, whom we have often tested and found diligent in many things, but now even more diligent because of his great confidence in you.
