III. A near future day of the Lord: A human invasion 2:1-27

Joel had spoken briefly of a coming day of the Lord in 1:15, but now he said more about it.

The term "the day of the Lord"seems to have arisen from the popular concept, in the ancient Near East, that a really great warrior king could consummate an entire military campaign is one single day.¹⁶Thus, as the Israelites used the term in relation to Yahweh, it reflected His greatness and pointed to His swift and effective dispatch of His enemies on a given occasion. Sometimes the term refers to such a judgment in the near past or future, and sometimes it refers to one in the distant future (eschaton).¹⁷

 A. The invading army 2:1-11

The Lord revealed that an army of human beings rather than locusts would soon assail Jerusalem. He described this army at length to stress the danger that His people faced and to motivate them to repent.

 B. A call to repentance 2:12-17

Such an awesome prospect of invasion led Joel to appeal to the people of Jerusalem to repent. This would hopefully turn away God's judgment. He voiced two appeals, but, unusually, he did not say what the sins of the people were. Evidently they were known well enough at the time.

 C The possibility of forgiveness and restoration 2:18-27

Joel next revealed the Lord's response and comforting words in view of the people's private and public repentance. It is unclear whether he meant that the Lord had responded or would respond. The problem is the Hebrew perfect verbs, which can be rendered in English with either past for future verbs. Several English translations (NASB, NIV, AV) interpreted the Lord's response as being conditioned on the people's repentance and translated the verbs in the future tense. It is equally possible that Joel meant that God had already responded positively because the people had repented, which the prophet did not record. I prefer to view this section as what God promised to do if the people responded to Joel's call to repentance.

"Laments in the OT are sometimes followed by a divine oracle in which Yahweh, through a prophet, assures his people that their prayers will be answered (or sometimes rejected)."²³
