'False Prophets' in the Bible

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

And many false prophets shall arise, and shall lead many astray.

For there shall arise false Christs, and false prophets, and shall show great signs and wonders; so as to lead astray, if possible, even the elect.

for there shall arise false Christs and false prophets, and shall show signs and wonders, that they may lead astray, if possible, the elect.

Woe unto you , when all men shall speak well of you! for in the same manner did their fathers to the false prophets.

But there arose false prophets also among the people, as among you also there shall be false teachers, who shall privily bring in destructive heresies, denying even the Master that bought them, bringing upon themselves swift destruction.

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