21 Blow the trumpet in Zion,
and sound an alarm in my holy mountain!
Let all the inhabitants of the land tremble,
for the day of Yahweh comes,
for it is close at hand: 2 A day of darkness and gloominess,
a day of clouds and thick darkness.
As the dawn spreading on the mountains,
a great and strong people;
there has never been the like,
neither will there be any more after them,
even to the years of many generations. 3 A fire devours before them,
and behind them, a flame burns.
The land is as the garden of Eden before them,
and behind them, a desolate wilderness.
Yes, and no one has escaped them. 4 The appearance of them is as the appearance of horses,
and as horsemen, so do they run. 5 Like the noise of chariots on the tops of the mountains do they leap,
like the noise of a flame of fire that devours the stubble,
as a strong people set in battle array. 6 At their presence the peoples are in anguish.
All faces have grown pale. 7 They run like mighty men.
They climb the wall like warriors.
They each march in his line, and they don’t swerve off course. 8 Neither does one jostle another;
they march everyone in his path,
and they burst through the defenses,
and don’t break ranks. 9 They rush on the city.
They run on the wall.
They climb up into the houses.
They enter in at the windows like thieves. 10 The earth quakes before them.
The heavens tremble.
The sun and the moon are darkened,
and the stars withdraw their shining. 11 Yahweh thunders his voice before his army;
for his forces are very great;
for he is strong who obeys his command;
for the day of Yahweh is great and very awesome,
and who can endure it?

The Mercy of the LORD

12 “Yet even now,” says Yahweh, “turn to me with all your heart,
and with fasting, and with weeping, and with mourning.” 13 Tear your heart, and not your garments,
and turn to Yahweh, your God;
for he is gracious and merciful,
slow to anger, and abundant in loving kindness,
and relents from sending calamity. 14 Who knows? He may turn and relent,
and leave a blessing behind him,
even a meal offering and a drink offering to Yahweh, 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.
