Joel 2:3

Summons to Penitential Prayer for the Removal of the Judgment - Joel 2:1-17 This section does not contain a fresh or second address of the prophet, but simply forms the second part of his sermon of repentance, in which he repeats with still greater emphasis the command already hinted at in Joe 1:14-15, that there should be a meeting of the congregation for humiliation and prayer, and assigns the reason in a comprehensive picture of the approach of Jehovah's great and terrible judgment-day (Joe 2:1-11), coupled with the cheering assurance that the Lord will still take compassion upon His people, according to His great grace, if they will return to Him with all their heart (Joe 2:12-14); and then closes with another summons to the whole congregation to assemble for this purpose in the house of the Lord, and with instructions how the priests are to pray to the Lord (Joe 2:15-17).

In this chapter we have, I. A further description of that terrible desolation which should be made in the land of Judah by the locusts and caterpillars (Joe 2:1-11). II. A serious call to the people, when they are under this sore judgment, to return and repent, to fast and pray, and to seek unto God for mercy, with directions how to do this aright (Joe 2:12-17). III. A promise that, upon their repentance, God would remove the judgment, would repair the breaches made upon them by it, and restore unto them plenty of all good things (Joe 2:18-27). IV. A prediction of the setting up of the kingdom of the Messiah in the world, by the pouring out of the Spirit in the latter days (Joe 2:28-32). Thus the beginning of this chapter is made terrible with the tokens of God's wrath, but the latter end of it made comfortable with the assurances of his favour, and it is in the way of repentance that this blessed change is made; so that, though it is only the last paragraph of the chapter that points directly at gospel-times, yet the whole may be improved as a type and figure, representing the curses of the law invading men for their sins, and the comforts of the gospel flowing in to them upon their repentance.

2:3 The destruction wrought by the invading army would be like a raging wildfire. Before the attack, the land looked like the Garden of Eden, but afterwards, it would be nothing but desolation (a reversal of Isa 51:3 and Ezek 36:35).
