Jeremiah 28:15-17
Then the prophet Jeremiah said to the prophet Hananiah, “Listen, Hananiah! The LORD did not send you, but you have persuaded this people to trust in a lie. / Therefore this is what the LORD says: ‘I am about to remove you from the face of the earth. You will die this year because you have preached rebellion against the LORD.’” / And in the seventh month of that very year, the prophet Hananiah died.

Jeremiah 23:25-32
“I have heard the sayings of the prophets who prophesy lies in My name: ‘I had a dream! I had a dream!’ / How long will this continue in the hearts of these prophets who prophesy falsehood, these prophets of the delusion of their own minds? / They suppose the dreams that they tell one another will make My people forget My name, just as their fathers forgot My name through the worship of Baal. ...

Jeremiah 14:14-16
“The prophets are prophesying lies in My name,” replied the LORD. “I did not send them or appoint them or speak to them. They are prophesying to you a false vision, a worthless divination, the futility and delusion of their own minds. / Therefore this is what the LORD says about the prophets who prophesy in My name: I did not send them, yet they say, ‘No sword or famine will touch this land.’ By sword and famine these very prophets will meet their end! / And the people to whom they prophesy will be thrown into the streets of Jerusalem because of famine and sword. There will be no one to bury them or their wives, their sons or their daughters. I will pour out their own evil upon them.

Ezekiel 13:1-9
Then the word of the LORD came to me, saying, / “Son of man, prophesy against the prophets of Israel who are now prophesying. Tell those who prophesy out of their own imagination: Hear the word of the LORD! / This is what the Lord GOD says: Woe to the foolish prophets who follow their own spirit yet have seen nothing. ...

Deuteronomy 18:20-22
But if any prophet dares to speak a message in My name that I have not commanded him to speak, or to speak in the name of other gods, that prophet must be put to death.” / You may ask in your heart, “How can we recognize a message that the LORD has not spoken?” / When a prophet speaks in the name of the LORD and the message does not come to pass or come true, that is a message the LORD has not spoken. The prophet has spoken presumptuously. Do not be afraid of him.

2 Peter 2:1-3
Now there were also false prophets among the people, just as there will be false teachers among you. They will secretly introduce destructive heresies, even denying the Master who bought them—bringing swift destruction on themselves. / Many will follow in their depravity, and because of them the way of truth will be defamed. / In their greed, these false teachers will exploit you with deceptive words. The longstanding verdict against them remains in force, and their destruction does not sleep.

Matthew 7:15-20
Beware of false prophets. They come to you in sheep’s clothing, but inwardly they are ravenous wolves. / By their fruit you will recognize them. Are grapes gathered from thornbushes, or figs from thistles? / Likewise, every good tree bears good fruit, but a bad tree bears bad fruit. ...

1 John 4:1
Beloved, do not believe every spirit, but test the spirits to see whether they are from God. For many false prophets have gone out into the world.

2 Timothy 4:3-4
For the time will come when men will not tolerate sound doctrine, but with itching ears they will gather around themselves teachers to suit their own desires. / So they will turn their ears away from the truth and turn aside to myths.

Now the Spirit expressly states that in later times some will abandon the faith to follow deceitful spirits and the teachings of demons, / influenced by the hypocrisy of liars, whose consciences are seared with a hot iron.

2 Corinthians 11:13-15
For such men are false apostles, deceitful workers, masquerading as apostles of Christ. / And no wonder, for Satan himself masquerades as an angel of light. / It is not surprising, then, if his servants masquerade as servants of righteousness. Their end will correspond to their actions.

Micah 3:5-7
This is what the LORD says: “As for the prophets who lead My people astray, who proclaim peace while they chew with their teeth, but declare war against one who puts nothing in their mouths: / Therefore night will come over you without visions, and darkness without divination. The sun will set on these prophets, and the daylight will turn black over them. / Then the seers will be ashamed and the diviners will be disgraced. They will all cover their mouths because there is no answer from God.”

Zechariah 13:2-3
And on that day, declares the LORD of Hosts, I will erase the names of the idols from the land, and they will no longer be remembered. I will also remove the prophets and the spirit of impurity from the land. / And if anyone still prophesies, his father and mother who bore him will say to him, ‘You shall not remain alive, because you have spoken falsely in the name of the LORD.’ When he prophesies, his father and mother who bore him will pierce him through.

Isaiah 30:9-11
These are rebellious people, deceitful children, children unwilling to obey the LORD’s instruction. / They say to the seers, “Stop seeing visions!” and to the prophets, “Do not prophesy to us the truth! Speak to us pleasant words; prophesy illusions. / Get out of the way; turn off the road. Rid us of the Holy One of Israel!”
