The earth shall quake before them
The inhabitants of it, because of the desolating judgments they bring with them, and those enemies that are signified by them: the heavens shall tremble;
being obscured by them: the sun and moon shall be dark;
the locusts sometimes come in such large numbers as to intercept the rays of the sun. Pliny F20 says they sometimes darken it; and though some thought they did not fly in the night, because of the cold; this he observes is owing to their ignorance, not considering that they pass over wide seas to distant countries; and this will account for it how the moon also may be darkened by them, and the stars, as follows: and the stars shall withdraw their shining;
though all this may be understood in a figurative sense of the great consternation that all sorts of persons should be in at such calamities coming upon the land, either by locusts, or by enemies; as the king, queen, nobles, and the common people of the land, signified by sun, moon, and stars, heaven and earth.
