'Set on Fire' in the Bible

The warriors of Babylon have stopped fighting. They stay in their strongholds; their strength is dried up; they have become like women. Her buildings are set on fire; the bars of her gates are broken.

This is what the LORD of the Heavenly Armies says: "The broad wall of Babylon will be completely leveled, and its high gate set on fire. and so the nations toil for nothing, and the nations weary themselves only for fire."
