But I appeal to God as my witness [i.e., to verify that I am telling the truth]; it was in order to spare you [i.e., from a disciplinary action] that I decided not to return to Corinth.

For I consider myself not to be one bit inferior to those "super apostles." [Note: Paul is referring to his opponents there in Corinth who claimed apostolic authority].

But what I am doing, I will continue to do, so that I can cut off the opportunity from those who want an occasion [to receive financial support for themselves because of my example of receiving it]. They want to boast [that they are preaching] on the same terms as I do. [Note: Paul's argument seems to be that one reason for his foregoing financial support was so those "super apostles" in Corinth (see verse 5) would not be able to use his example to wrongfully exact financial support from the church].

I am ashamed to say that we were [too] weak to do such things. [Note: Paul is probably saying, sarcastically, "We are too 'weak' to take financial advantage of people and mistreat them the way those 'super apostles' there in Corinth were doing"]. Yet, in whatever [matters] anyone [there] dares to boast about, (now I am really speaking foolishly), I will dare to boast also.

I have become foolish [i.e., by my boasting], but you made me do it [i.e., in order to vindicate myself]. For I should have been commended by you [i.e., for my effective ministry there in Corinth], because I was not inferior in any way to those "super apostles" [See 11:5], even though I am nothing.

I told you the last time I was there, and now before returning, I [again] warn those who have sinned in the past as well as the rest, that if I come again I will not spare you [i.e., I will rebuke and discipline you],
