1 Corinthians 15:33

He that walketh with wise men shall be wise: but a companion of fools shall be destroyed.

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

Your glorying is not good. Know ye not that a little leaven leaveneth the whole lump?

Forsake the foolish, and live; and go in the way of understanding.

Let no man deceive you with vain words: for because of these things cometh the wrath of God upon the children of disobedience.

Be not deceived; God is not mocked: for whatsoever a man soweth, that shall he also reap.

But shun profane and vain babblings: for they will increase unto more ungodliness. And their word will eat as doth a canker: of whom is Hymeneus and Philetus; Who concerning the truth have erred, saying that the resurrection is past already; and overthrow the faith of some.

Know ye not that the unrighteous shall not inherit the kingdom of God? Be not deceived: neither fornicators, nor idolaters, nor adulterers, nor effeminate, nor abusers of themselves with mankind,

For there shall arise false Christs, and false prophets, and shall shew great signs and wonders; insomuch that, if it were possible, they shall deceive the very elect.

And many shall follow their pernicious ways; by reason of whom the way of truth shall be evil spoken of.

Looking diligently lest any man fail of the grace of God; lest any root of bitterness springing up trouble you, and thereby many be defiled;

For when they speak great swelling words of vanity, they allure through the lusts of the flesh, through much wantonness, those that were clean escaped from them who live in error. While they promise them liberty, they themselves are the servants of corruption: for of whom a man is overcome, of the same is he brought in bondage. For if after they have escaped the pollutions of the world through the knowledge of the Lord and Saviour Jesus Christ, they are again entangled therein, and overcome, the latter end is worse with them than the beginning.

And many false prophets shall rise, and shall deceive many.

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 the great dragon was cast out, that old serpent, called the Devil, and Satan, which deceiveth the whole world: he was cast out into the earth, and his angels were cast out with him.

And all that dwell upon the earth shall worship him, whose names are not written in the book of life of the Lamb slain from the foundation of the world. If any man have an ear, let him hear. He that leadeth into captivity shall go into captivity: he that killeth with the sword must be killed with the sword. Here is the patience and the faith of the saints. And I beheld another beast coming up out of the earth; and he had two horns like a lamb, and he spake as a dragon. And he exerciseth all the power of the first beast before him, and causeth the earth and them which dwell therein to worship the first beast, whose deadly wound was healed. And he doeth great wonders, so that he maketh fire come down from heaven on the earth in the sight of men, And deceiveth them that dwell on the earth by the means of those miracles which he had power to do in the sight of the beast; saying to them that dwell on the earth, that they should make an image to the beast, which had the wound by a sword, and did live.
