Matthew 24:11

Beware of false prophets, which come to you in sheep's clothing, but inwardly they are ravening wolves.

For many shall come in my name, saying, I am Christ; and shall deceive many.

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.

Now the Spirit speaketh expressly, that in the latter times some shall depart from the faith, giving heed to seducing spirits, and doctrines of devils;

But there were false prophets also among the people, even as there shall be false teachers among you, who privily shall bring in damnable heresies, even denying the Lord that bought them, and bring upon themselves swift destruction.

Little children, it is the last time: and as ye have heard that antichrist shall come, even now are there many antichrists; whereby we know that it is the last time.

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