2 Corinthians 11:7-10

7Was it a sin for me to humble myself in order to exalt you, because I preached the gospel of God to you free of charge? 8I robbed other churches by accepting their support in order to serve you. 9And when I was with you and in need, I was not a burden to anyone; for the brothers who came from Macedonia supplied my needs. I have refrained from being a burden to you in any way, and I will continue to do so. 10As surely as the truth of Christ is in me, this boasting of mine will not be silenced in the regions of Achaia.
