2 Corinthians 11:7-10, 12

Have I committed an offence in abasing myself that ye might be exalted, because I have preached to you the gospel of God freely? I robbed other churches, taking wages of them, to do you service. And when I was present with you, and wanted, I was chargeable to no man: for that which was lacking to me the brethren which came from Macedonia supplied: and in all things I have kept myself from being burdensome unto you, and so will I keep myself. As the truth of Christ is in me, no man shall stop me of this boasting in the regions of Achaia.

But what I do, that I will do, that I may cut off occasion from them which desire occasion; that wherein they glory, they may be found even as we.
