2 Corinthians 11:3-14

But I fear, lest by any means, as the serpent beguiled Eve in his craftiness, your minds should be corrupted from the simplicity and the purity that is toward Christ. For if he that cometh preacheth another Jesus, whom we did not preach, or if ye receive a different spirit, which ye did not receive, or a different gospel, which ye did not accept, ye do well to bear with him. For I reckon that I am not a whit behind the very chiefest apostles. But though I be rude in speech, yet am I not in knowledge; nay, in every way have we made this manifest unto you in all things. Or did I commit a sin in abasing myself that ye might be exalted, because I preached to you the gospel of God for nought? I robbed other churches, taking wages of them that I might minister unto you; and when I was present with you and was in want, I was not a burden on any man; for the brethren, when they came from Macedonia, supplied the measure of my want; and in everything I 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 glorying in the regions of Achaia. Wherefore? because I love you not? God knoweth. But what I do, that I will do, that I may cut off occasion from them that desire an occasion; that wherein they glory, they may be found even as we. For such men are false apostles, deceitful workers, fashioning themselves into apostles of Christ. And no marvel; for even Satan fashioneth himself into an angel of light.
