Therefore will not we fear, though the earth be removed; or, though the earth change—a somewhat vague expression, probably to be understood of political changes and revolutions (see Psalms 46:6). And though the mountains be carried into the midst of the sea; rather, and though the mountains be hurled into the heart of the seas.
A metaphor for still more strange and violent disturbances and commotions. The revolutions and disturbances intended are probably those caused by the Assyrian career of conquest briefly described in Isaiah 10:5-14; Isaiah 37:18-27, and fully set forth in the annals of the Assyrian kings.
