21 Blow the trumpet in Zion; sound the alarm on my holy mountain! Let all the inhabitants of the land tremble, for the day of the Lord is coming, it is near- 2 a day of darkness and gloom, a day of clouds and thick darkness! Like blackness spread upon the mountains a great and powerful army comes; their like has never been from of old, nor will be again after them in ages to come. 3 Fire devours in front of them, and behind them a flame burns. Before them the land is like the garden of Eden, but after them a desolate wilderness, and nothing escapes them. 4 They have the appearance of horses, and like war-horses they charge. 5 As with the rumbling of chariots, they leap on the tops of the mountains, like the crackling of a flame of fire devouring the stubble, like a powerful army drawn up for battle. 6 Before them peoples are in anguish, all faces grow pale. 7 Like warriors they charge, like soldiers they scale the wall. Each keeps to its own course, they do not swerve from their paths. 8 They do not jostle one another, each keeps to its own track; they burst through the weapons and are not halted. 9 They leap upon the city, they run upon the walls; they climb up into the houses, they enter through the windows like a thief. 10 The earth quakes before them, the heavens tremble. The sun and the moon are darkened, and the stars withdraw their shining. 11 The Lord utters his voice at the head of his army; how vast is his host! Numberless are those who obey his command. Truly the day of the Lord is great; terrible indeed-who can endure it?
12 Yet even now, says the Lord, return to me with all your heart, with fasting, with weeping, and with mourning; 13 rend your hearts and not your clothing. Return to the Lord, your God, for he is gracious and merciful, slow to anger, and abounding in steadfast love, and relents from punishing. 14 Who knows whether he will not turn and relent, and leave a blessing behind him, a grain offering and a drink offering for the Lord, your God?

Commentary on Joel 2:1-14
(Read Joel 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.
