Commentators explain that Isaiah uses powerful imagery to depict Babylon's fall. Personified as a 'virgin daughter'—previously unconquered and living in luxury—she is commanded by God to leave her throne and sit in the dust. This signifies a complete and humiliating reversal from the pinnacle of power to a state of mourning and subjugation. As John Calvin notes, this is not a mere prediction but a divine decree issued with absolute authority.
