2 Corinthians 11:12

I know (saith the apostle) that there are some amongst you who, out of their hatred to me, would seek any occasion to asperse me to justify themselves. If I had (as I might) have taken wages amongst you for my labours, they would either have taken occasion from it to have aspersed me, (as doing what I did from a mercenary spirit), or at least to have justified themselves in their exactings upon you. I had a mind to prevent any such occasions of boasting. That wherein they glory, they may be found even as we: it should seem by these words, that some teachers in this church, being (possibly) men of estates, required no maintenance of the people; and would have taken advantage against the apostle, if he had taken any: or, possibly, some others exacted upon them unreasonably, who, had Paul taken wages, would have justified themselves by his example. The apostle therefore was resolved to cut off from them any pretence or occasion of boasting, and to do whatever any of them did, in sparing the Corinthians as to the business of their purses.
