Joel 2 is a more complete description of this nation of insects that has overrun Judea, describing the individual soldiers and their actions. We must read these verses carefully to notice that he is describing the locusts metaphorically to raise the reader's emotional response.
Joel 2:4 says they have “the appearance of horsemen”; they do not actually look like horses or have horses, but they run as horses do, headlong and swiftly. This is also a reference to their warlike activity, since the Bible connects horses with war (see Proverbs 21:31). This exact comparison is made in Revelation 9:7, part of the description of the fifth trumpet plague: “The shape of the locusts was like horses prepared for battle.”
Verse 5 describes their assault as so exceedingly massive and heavy that the beating of their wings sounds like chariots on the move. Two verses later, Joel depicts their rush toward their prey, writing that they run “like mighty men, . . . every one marches in formation,” up and over the walls. Nothing stops or hinders them. They are a determined, unstoppable force.
In the King James Version, verse 8 reads, “. . . when they fall upon the sword, they shall not be wounded.” The translators of The Amplified Version seem to have a better grasp of the situation, rendering this as, “And they burst through and upon the weapons, yet they are not wounded and do not change their course.” Locusts certainly would not be hurt by landing on a sword, and trying to kill millions of them with ordinary hand weapons would be a futile endeavor indeed.
The following verse shows them in firm control of every part of the city, running wherever they please. They climb into houses through the windows and any other opening, covering the walls and roofs, part of the living quarters at the time. No soldier with actual weapons at the ready would try to climb through a window if a doorway were readily available! Going in through a window would be an awkward and dangerous way of entering a building. But for locusts, such an entry would be natural.
Finally, in Joel 2:11, God takes responsibility for this “nation” of insect soldiers on the march: “The LORD gives voice before His army, for His camp is very great; for strong is the One who executes His word. For the day of the LORD is great and very terrible; who can endure it?” He repeats His ownership of this army in verse 25, calling it once again “My great army which I sent among you.” He sent it as punishment for sin and breaking the covenant, and the locusts did their jobs with brutal efficiency.
What happened to God's vast army of locusts? Joel 2:20 speaks primarily of the future human fulfillment of this, describing a “northern army” removed into a barren, uninhabited area between the Dead Sea and the Mediterranean Sea, where its soldiers will die and rot with a great stench. Perhaps a similar thing happened to the horde of locusts.
Joel does not record how many died as a result of this catastrophe, but it must have been significant. Because there are no crops with which to feed those left alive, God must send them “grain and new wine and oil” (verse 19). Unless He sent a miracle that caused the crops to rise up and mature overnight, as He did to the gourd that provided shade for Jonah (Jonah 4:6), it would have to be in the form of humanitarian aid from other nations. Without such an extraordinary miracle, several years must pass before the agricultural cycle returns to normal productivity.
In verse 22, the pastures are restored, as are the fruit and fig trees and grape vines. We could expect that the wheat and barley harvests would soon resume. Again, without an absolutely stunning miracle, the restoration of these crops takes time. When fruit trees have had their bark removed and eaten by locusts, those trees are dead and need to be replaced.
After fruit trees are replanted, its fruit cannot be eaten until the fifth year, as Leviticus 19:23-25 commands. So the fruit trees could not be counted on to help relieve the famine.
Nevertheless, eventually, the productivity of the land returns to normal. The former and the latter rains water the earth on schedule (Joel 2:23), a sign of God's faithfulness to His people and the covenant. Wheat fills the threshing floors (meaning that a bumper crop was harvested), and vats of new wine and oil overflow (verse 24). Actually, it appears as if conditions were improved to better than normal, with peace ample food and the resulting joy and gladness!
