Joel 2:9,10 - Joseph Benson’s Commentary on the Old and New Testaments

They shall run to and fro in the city No place shall be inaccessible to them, nor free from them. “Every place,” says St. Jerome, “lies open to them; for they infest not only the fields, and the fruits of the earth, but creep into cities, houses, and the most secret recesses.” The earth shall quake before them The inhabitants of the land of Judea shall be seized with a horrible dread at their approach. The heavens shall look dark and dismal, because they shall come in such swarms as to intercept the rays of the sun, and the light of the moon and stars. By the expression, The heavens shall tremble, is either meant, that the whole state of the kingdom of Judah, of the very highest in rank and dignity, as well as the meanest, should be struck with a panic at this unusual judgment; or else that the locusts should so fill the sky, that, at a great height, it would appear as if the heavens themselves trembled.
