Did I make a mistake when I humbled myself so that you might be exalted, because I preached the gospel of God to you without charge? I plundered other churches by accepting from them in order to minister to you. And when I was with you and in need, I did not burden anyone, for the brothers who came from Macedonia supplied my needs. So I refrained and will refrain from burdening you in any way. By the truth of Christ in me, this boast of mine shall not be silenced in the regions of Achaia....
2 Corinthians 11:7–33
