'Minds' in the Bible

Then the LORD told me, "The prophets are prophesying lies in my name. I didn't send them, I didn't command them, and I didn't speak to them. They're proclaiming to you false visions, worthless predictions, and the delusions of their own minds.

This is what the LORD of the Heavenly Armies says: "Don't listen to the words of the prophets who are prophesying to you; they're giving you false hopes. They declare visions from their own minds they don't come from the LORD!
