John Gill Commentary 2 Corinthians 12:17

"Did I take advantage of you by any one of them whom I have sent unto you?" — 2 Corinthians 12:17 (ASV)

Did I make a gain of you He appeals to the Corinthians against such calumnies and false insinuations, whether ever he had circumvented them in such a manner, or had ever used such artful methods to pillage them; or whether ever he had discovered any covetous disposition towards anything of theirs; or had employed any persons to draw out their substance from them, and get it for himself:

he owns he had sent some persons to them on different errands, and asks if he had dealt fraudulently with them, by any of them whom , says he, I have sent to you :

he desires them to name one single person of the many who came to them from him, that had received any money from them for him; or that they had any reason to believe he had employed for such purposes; and if they could not pitch on a single instance, they ought therefore to look upon this as a downright slander and calumny.
