2 Corinthians 11:5-9

For I consider myself not in the least inferior to the most eminent apostles.

But even if I am unskilled in speech, yet I am not so in knowledge; in fact, in every way we have made this evident to you in all things.

Or did I commit a sin by humbling myself so that you might be exalted, because I preached the gospel of God to you without charge?

I robbed other churches by taking wages from them to serve you;

and when I was present with you and was in need, I was not a burden to anyone; for when the brothers came from Macedonia they fully supplied my need, and in everything I kept myself from being a burden to you, and will continue to do so.
