Matthew 24:4

For thus saith the LORD of hosts, the God of Israel; Let not your prophets and your diviners, that be in the midst of you, deceive you, neither hearken to your dreams which ye cause to be dreamed.

And Jesus answering them began to say, Take heed lest any man deceive you:

And he said, Take heed that ye be not deceived: for many shall come in my name, saying, I am Christ; and the time draweth near: go ye not therefore after them.

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.

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;

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