THE COMING JUDGMENT A MOTIVE TO REPENTANCE. PROMISE OF BLESSINGS IN THE LAST DAYS. (Joel 2:1-32) 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. Blow . . . trumpet--to sound an alarm of coming war (Num 10:1-10; Hos 5:8; Amo 3:6); the office of the priests. Joe 1:15 is an anticipation of the fuller prophecy in this chapter.
