'Cliffs' in the Bible

Leave your towns, you inhabitants of Moab. Go and live in the cliffs. Be like a dove that makes its nest high on the sides of a ravine.

The Lord says, "Beware! I am opposed to you, Babylon! You are like a destructive mountain that destroys all the earth. I will unleash my power against you; I will roll you off the cliffs and make you like a burned-out mountain.
