'False Prophets' in the Bible

Beware of false prophets; they come to you with the garb of sheep but at heart they are ravenous wolves.

Many false prophets will rise and mislead many.

for false Christs and false prophets will rise and bring forward great signs and wonders, so as to mislead the very elect, ??if that were possible.

for false Christs and false prophets will rise and perform signs and wonders to mislead the elect if they can.

Woe to you when all men speak well of you! that is just what their fathers did to the false prophets.

Still, false prophets did appear among the People, as among you also there will be false teachers, men who will insinuate destructive heresies, even disowning the Lord who ransomed them; they bring rapid destruction on themselves,

Do not believe every spirit, beloved, but test the spirits to see if they come from God; for many false prophets have emerged in the world.
