'Whom' in the Bible

not that we rule [like dictators] over your faith, but rather we work with you for [the increase of] your joy; for in your faith you stand firm [in your strong conviction that Jesus of Nazareth—the Messiah—is the Son of God, through whom we obtain eternal salvation].

For if I cause you grief [by a well-deserved rebuke], who then provides me enjoyment but the very one whom I have made sad?

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.

For it is not he who commends and praises himself who is approved [by God], but it is the one whom the Lord commends and praises.

Did I take advantage of you or make any money off you through any of the messengers I sent you? [Certainly not!]
