2 Corinthians 11:7, 9

Have I committed a sin by degrading myself to dignify you? Was I wrong to preach the gospel of God to you free of charge?

Remember, when I was with you I didn’t bother anyone when I needed money, for my needs were always supplied by my Macedonian friends. So I was careful, and will continue to be careful, that I never become a burden to you in any way.
