'Beware' in the Bible

"This is what the Lord says: 'Beware! An army is coming from a land in the north. A mighty nation is stirring into action in faraway parts of the earth.

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.
