2 Corinthians 11:13

"Which is not another; but there be some that trouble you, and would pervert the gospel of Christ."

"I know thy works, and thy labour, and thy patience, and how thou canst not bear them which are evil: and thou hast tried them which say they are apostles, and are not, and hast found them liars:"

"Beloved, believe not every spirit, but try the spirits whether they are of God: because many false prophets are gone out into the world."

"Beware of dogs, beware of evil workers, beware of the concision."

"And that because of false brethren unawares brought in, who came in privily to spy out our liberty which we have in Christ Jesus, that they might bring us into bondage:"

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

"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."

"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."

"That we henceforth be no more children, tossed to and fro, and carried about with every wind of doctrine, by the sleight of men, and cunning craftiness, whereby they lie in wait to deceive;"

"And this I say, lest any man should beguile you with enticing words."
