'Vision' in the Bible

Here is a message about the Valley of Vision: What is the reason that all of you go up to the rooftops?

For the sovereign master, the Lord who commands armies, has planned a day of panic, defeat, and confusion. In the Valley of Vision people shout and cry out to the hill.

It will be like a dream, a night vision. There will be a horde from all the nations that fight against Ariel, those who attack her and her stronghold and besiege her.
