But what I do, that I will do

I may cut off occasion from them which desire
meaning the false apostles, who sought for, and were desirous of every occasion and opportunity of exalting themselves, and reproaching him: that wherein they glory, they may be found even as we; the sense of which according to some interpreters is, that whereas some of the false apostles, at least who were rich men, took nothing for preaching, but gave their labours freely, were very desirous that the apostle would receive of the churches in these parts, that they might have an occasion against him, and an opportunity of showing themselves, as in learning and eloquence, so in this respect, to be superior to him, in that they preached freely, and he for gain; wherefore to cut off such an occasion, the apostle determines he would take nothing; that in this very thing which they boasted of, that they preached the Gospel freely, they might appear to be at most to be but upon a par with the apostle, and not to exceed him. This sense would seem very appropriate, was it a clear point that the false apostles received nothing for preaching; but the contrary is most evident; wherefore the apostle's meaning is, that these men were desirous that he would take wages, because they did; that in this respect he might not excel them, and that they might be able to plead his example and authority, and so get an occasion of extorting more money from the Corinthians: wherefore to cut off all such occasion from them, the apostle resolves to take nothing himself; that whereas they boasted they were equal to, or superior to the apostles, they might be found, would they follow their example, even as they, not taking any money at all of them, and poor, and working with their own hands.
