'False Prophets' in the Bible

“Beware of the false prophets, who come to you in sheep’s clothing, but inwardly are ravenous wolves.

Many false prophets will arise and will mislead many.

For false Christs and false prophets will arise and will show great signs and wonders, so as to mislead, if possible, even the elect.

for false Christs and false prophets will arise, and will show signs and wonders, in order to lead astray, if possible, the elect.

Woe to you when all men speak well of you, for their fathers used to treat the false prophets in the same way.

But false prophets also arose among the people, just as there will also be false teachers among you, who will secretly introduce destructive heresies, even denying the Master who bought them, bringing swift destruction upon themselves.

Beloved, do not believe every spirit, but test the spirits to see whether they are from God, because many false prophets have gone out into the world.
