“I did not send these prophets,

But they ran.

I did not speak to them,

But they prophesied.

But if they had stood in My council,

Then they would have announced My words to My people,

And would have turned them back from their evil way

And from the evil of their deeds.”

…

“Therefore behold, I am against the prophets,” declares the LORD, “who steal My words from each other.

Behold, I am against the prophets,” declares the LORD, “who use their tongues and declare, ‘The LORD declares.’

Behold, I am against those who have prophesied false dreams,” declares the LORD, “and related them and led My people astray by their falsehoods and reckless boasting; yet I did not send them or command them, nor do they furnish this people the slightest benefit,” declares the LORD.

— Jeremiah 23:21–22, 30–32 (NASB95)

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. Many will follow their sensuality, and because of them the way of truth will be maligned; and in their greed they will exploit you with false words; their judgment from long ago is not idle, and their destruction is not asleep.

— 2 Peter 2:1–3 (NASB95)

And the devil who deceived them was thrown into the lake of fire and brimstone, where the beast and the false prophet are also; and they will be tormented day and night forever and ever.

— Revelation 20:10 (NASB95)
