'False Prophets' in the Bible

And hold from false prophets which come in to you in sheep's dresses, but within they are rapacious wolves.

And many false prophets shall be raised up, and deceive many.

For false Christs, and false prophets, shall be raised up, and give great signs and wonders; so as to deceive, if possible, also the chosen.

For false Christs and false prophets shall be raised up, and shall give signs and wonders, to deceive, if possible, also the chosen.

Woe to you when all men speak well of you! for according to these did their fathers to the false prophets.

And also were there false prophets among the people, as also among you shall be false teachers, who shall privately bring in doctrines of perdition, and denying the master having purchased them, having brought upon themselves swift destruction.

Dearly beloved, believe not every spirit, but try the spirits if they are of God: for many false prophets have come out into the world.
