2:1-14 The priests were to alarm the people with the near approach of the Divine judgments. It is the work of ministers to warn of the fatal consequences of sin, and to reveal the wrath from heaven against the ungodliness and unrighteousness of men. The striking description which follows, shows what would attend the devastations of locusts, but may also describe the effects from the ravaging of the land by the Chaldeans. If the alarm of temporal judgments is given to offending nations, how much more should sinners be warned to seek deliverance from the wrath to come! Our business therefore on earth must especially be, to secure an interest in our Lord Jesus Christ; and we should seek to be weaned from objects which will soon be torn from all who now make idols of them. There must be outward expressions of sorrow and shame, fasting, weeping, and mourning; tears for trouble must be turned into tears for the sin that caused it. But rending the garments would be vain, except their hearts were rent by abasement and self-abhorrence; by sorrow for their sins, and separation from them. There is no question but that if we truly repent of our sins, God will forgive them; but whether he will remove affliction is not promised, yet the probability of it should encourage us to repent.

The fifth trumpet, or first woe, in the parallel passage (Re 9:1-11), cannot be literal: for in Re 9:11 it is said, "they had a king over them, the angel of the bottomless pit"—in the Hebrew, Abaddon ("destroyer"), but in the Greek, Apollyon—and (Re 9:7) "on their heads were as it were crowns like gold, and their faces were as the faces of men." Compare Joe 2:11, "the day of the Lord … great and very terrible"; implying their ultimate reference to be connected with Messiah's second coming in judgment. The locust's head is so like that of a horse that the Italians call it cavalette. Compare Job 39:20, "the horse … as the grasshopper," or locust.

run—The locust bounds, not unlike the horse's gallop, raising and letting down together the two front feet.
