'False Prophets' in the Bible

"Beware of the false prophets, who come to you disguised as sheep but are ravenous wolves underneath.

Many false prophets will appear, and many will be misled by them,

for false Christs and false prophets will appear, and they will show great signs and wonders to mislead God's chosen people if they can.

For false Christs and false prophets will appear, and they will show signs and wonders to mislead God's chosen people if they can.

"Alas for you when everyone speaks well of you, for that is the way their forefathers treated the false prophets!

There were false prophets too among the people, just as there will be false teachers among you, who will introduce destructive sects and deny the Master who has bought them, thus bringing on themselves swift destruction.

Dear friends, do not believe every inspired utterance, but test the utterances to see whether they come from God, for many false prophets have come out into the world.
