The Bible Says Commentary on the Book of Joel
Joel is often taken as a lament about a recent invasion of locusts that serves as a picture of an impending foreign invasion unless Israel repents. This commentary will take the position that the locust invasion represents a prediction regarding a series of foreign invaders who will occupy and ravage the land of Israel. This seems to best fit the passage. In Joel 1, the prophet introduces the destructive locust plague which will consist of four different kinds of locusts: gnawing, swarming, creeping and stripping. These four kinds of locusts likely represent four succeeding nations who will invade and ravage Israel. Joel speaks of these events as though they have occurred, indicating the certainty of the prophetic prediction.
