2 Corinthians 11:7-9

Was it a sin for me to lower myself in order to elevate you by preaching the gospel of God to you free of charge? I robbed other churches by receiving support from them so as to serve you. And when I was with you and needed something, I was not a burden to anyone, for the brothers who came from Macedonia supplied what I needed. I have kept myself from being a burden to you in any way, and will continue to do so.
