And we are sending along with them our brother whose earnestness has been proven many times and in many ways, and now even more so by his great confidence in you.

and we sent with them our brother, whom we proved in many things many times being diligent, and now much more diligent, by the great confidence that is toward you,

And we have sent with them our brother whom we have often proved to be of diligent zeal in many things, and now more diligently zealous through the great confidence [he has] as to you.
