2 Corinthians 11:6-10

But though I be rude in speech, yet not in knowledge; but we have been throughly made manifest among you in all things.

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.
