Blow ye {a} the trumpet in Zion, and sound an alarm in my holy mountain: let all the inhabitants of the land tremble: for the day of the LORD cometh, for it is nigh at hand;

(a) He shows the great judgments of God which are at hand, unless they repent.

CHAPTER 2

Joe 2:1-32. The Coming Judgment a Motive to Repentance. Promise of Blessings in the Last Days.

A more terrific judgment than that of the locusts is foretold, under imagery drawn from that of the calamity then engrossing the afflicted nation. He therefore exhorts to repentance, assuring the Jews of Jehovah's pity if they would repent. Promise of the Holy Spirit in the last days under Messiah, and the deliverance of all believers in Him.

1. Blow . trumpet-to sound an alarm of coming war (Nu 10:1-10; Ho 5:8; Am 3:6); the office of the priests. Joe 1:15 is an anticipation of the fuller prophecy in this chapter.

Matthew Henry's Concise Commentary

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.
