Structure

When the earth shakes, some are meant to go down.

The arrogance of man will be brought low
    and human pride humbled;
the Lord alone will be exalted in that day,
18     and the idols will totally disappear.

19 People will flee to caves in the rocks
    and to holes in the ground
from the fearful presence of the Lord
    and the splendor of his majesty,
    when he rises to shake the earth.

Isaiah 2:17-19 NIV
