2 Corinthians 11:8-13

I robbed other churches by accepting support from them in order to serve you. And when I was with you and was in need, I did not burden anyone, for the brothers who came from Macedonia supplied my need. So I refrained and will refrain from burdening you in any way. As the truth of Christ is in me, this boasting of mine will not be silenced in the regions of Achaia. And why? Because I do not love you? God knows I do! And what I am doing I will continue to do, in order to undermine the claim of those who would like to claim that in their boasted mission they work on the same terms as we do. For such men are false apostles, deceitful workmen, disguising themselves as apostles of Christ.
