Joel 2:10

The earth shall quake before them; the heavens shall tremble: the sun and the moon shall be dark, and the stars shall withdraw their shining:

The earth shall quake before them - i:e., the inhabitants of the earth quake with fear of them.

The heavens shall tremble - i:e., "the powers of the heavens shall be shaken" (); its illumining powers are disturbed by the locusts, which intercept the sunlight with their dense flying swarm. These, however, are but the images of revolutions of states causal by such foes as were to invade Judea.
