Matthew 13:39

But while men slept, his enemy came and sowed tares among the wheat, and went his way.

For we are not as many, which corrupt the word of God: but as of sincerity, but as of God, in the sight of God speak we in Christ.

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. And no marvel; for Satan himself is transformed into an angel of light. Therefore it is no great thing if his ministers also be transformed as the ministers of righteousness; whose end shall be according to their works.

Wherein in time past ye walked according to the course of this world, according to the prince of the power of the air, the spirit that now worketh in the children of disobedience:

Put on the whole armour of God, that ye may be able to stand against the wiles of the devil.

And then shall that Wicked be revealed, whom the Lord shall consume with the spirit of his mouth, and shall destroy with the brightness of his coming: Even him, whose coming is after the working of Satan with all power and signs and lying wonders, And with all deceivableness of unrighteousness in them that perish; because they received not the love of the truth, that they might be saved. And for this cause God shall send them strong delusion, that they should believe a lie:
