Colossians 2:4

And Jesus answered and said unto them, Take heed that no man deceive you.

For false Christs and false prophets shall rise, and shall shew signs and wonders, to seduce, if it were possible, even the elect.

Also of your own selves shall men arise, speaking perverse things, to draw away disciples after them.

For they that are such serve not our Lord Jesus Christ, but their own belly; and by good words and fair speeches deceive the hearts of the simple.

But I fear, lest by any means, as the serpent beguiled Eve through his subtilty, so your minds should be corrupted from the simplicity that is in Christ. For if he that cometh preacheth another Jesus, whom we have not preached, or if ye receive another spirit, which ye have not received, or another gospel, which ye have not accepted, ye might well bear with him. For I suppose I was not a whit behind the very chiefest apostles. 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. Wherefore? because I love you not? God knoweth. 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. For such are false apostles, deceitful workers, transforming themselves into the apostles of Christ.

Beware lest any man spoil you through philosophy and vain deceit, after the tradition of men, after the rudiments of the world, and not after Christ.
