10. earth . . . quake before them--that is, the inhabitants of the
earth quake with fear of them.
heavens . . . tremble--that is, the powers of heaven
(Mt 24:29);
its illumining powers are disturbed by the locusts which intercept the
sunlight with their dense flying swarms. These, however, are but the
images of revolutions of states caused by such foes as were to invade
Judea.
