'Vision' in the Bible

Then Yahweh said to me, The prophets prophesy lies in my name; I didn't send them, neither have I commanded them, neither spoke I to them: they prophesy to you a lying vision, and divination, and a thing of nothing, and the deceit of their own heart.

Thus says Yahweh of Armies, Don't listen to the words of the prophets who prophesy to you: they teach you vanity; they speak a vision of their own heart, and not out of the mouth of Yahweh.
