Verse 9. - They shall run to and fro in the city (or rush to the assault of the city. Wunsche, and so LXX., "They shall seize upon the city"); they shall run upon the wall, they shall climb up upon the houses; they shall enter in at the windows like a thief. In the first clause the comparison with an army still continues. The attack has succeeded, the city has been taken by assault, the victorious troops are running to and fro in the city; so far the locusts are fitly represented by an army vigorous in its advance, steady in its march, resistless in its assault, victorious in its attack, and masters of the captured city. The remainder of the ninth verse is not equally applicable to the figure and the fact in common, but belongs exclusively to the locusts themselves; they creep up the wall, climb up upon the houses, and find ingress even at the windows. "There is no road," says Jerome, "impassable to locusts. They penetrate into fields, and crops, and trees, and cities, and even the recesses of the bedchambers;" while Theodoret remarks of locusts that" not only when flying, but by creeping along the walls, they pass through the windows into the houses themselves." Thus there was no spot to which they could not find access, and no place secure from their assault. Yashoqqu. Aben Ezra and Kimchi both connect this word with shoq, a leg. The latter says, "It has the signification of shoq, a leg, and he mentions this word in respect to the locust, because its legs are long; and further, because it is continually going and seldom resting; and thus he (Isaiah) says, 'As the running to and fro of locusts shall he run upon them,' as if he said, 'a continual going up and down.'"

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.They shall run to and fro in the city,.... Leap about from place to place, as locusts do; see Isaiah 33:4; and as the Chaldeans did when they became masters of the city of Jerusalem; they ran about from place to place to seize upon their spoil and plunder:

they shall run upon the wall; which before they climbed, now they shall run upon, and go from tower to tower, as the Chaldeans did, and broke clown the walls and fortifications:

they shall climb up upon the houses, and enter in at the windows, like a thief; so the locusts entered into the houses of the Egyptians, Exodus 10:6; and Pliny says (s), they will eat through everything, and even the doors of houses. Theodoret on the place observes, that not only this may be done by enemies, what is here said,

"but even we have often seen it done by locusts; for not only flying, but even creeping up the walls, they enter into houses at the windows.''
