Do Not Let The Prophets Deceive You

Do not listen to what the prophets are prophesying to you.
They fill you with false hopes.
They speak visions from their own minds, not from the mouth of the Lord.
Do not let the prophets among you deceive you.
Do not listen to the dreams you encourage them to have.
They are prophesying lies to you in my name.
I have not sent them.
(Jeremiah, The Bible)

When men tell you to consult mediums and spiritists, who whisper and mutter, should not a people enquire of their God?
(Isaiah, The Bible)
