Introduction to the Book of Joel
The prophet Joel, whose Hebrew name is יואל בן פתואל (Yoel ben Petu’el, meaning “The Lord is God”), delivers a message deeply rooted in Judah’s spiritual and societal state. Little is known about Joel’s personal life, but his concern for the temple and worship suggests that he likely lived in Jerusalem.
Scholars often debate when Joel’s prophecy was delivered, but many suggest that it was during the post-exilic period—a time of rebuilding and spiritual renewal following the Babylonian exile.
Joel begins his prophecy with a description of a devastating locust plague and its catastrophic effects on Judah. Yet, Joel sees this disaster as more than just a natural occurrence. He interprets it as a divine judgment, foreshadowing something far greater: the Day of the Lord, a time when God will bring ultimate judgment and restoration.
What Type of Prophet Was Joel?
Joel is considered a classical prophet, part of the group of prophets who focus on themes of warning, repentance, and hope. Classical prophets typically deliver messages for the nation as a whole, and Joel’s call for repentance and his vision of the coming Day of the Lord places him firmly in this tradition.
Other classical prophets include Isaiah, Jeremiah, Ezekiel, and Hosea. These prophets shared similar themes of judgment, repentance, and future hope for Israel and Judah.
Joel’s message differs slightly from prophets like Isaiah or Jeremiah in that he doesn’t focus on specific sins of the people. Instead, his prophecy is more general, calling for a national turning back to God in light of the present disaster.
Joel’s broader view of disaster, combined with his vision of God’s restoration, connects him with other classical prophets, but his message stands out due to its unique focus and style.
Within the broader category of prophets, there are different types:
- Classical Prophets: These include Joel, Isaiah, Jeremiah, Ezekiel, and Hosea. They focus on warnings about impending judgment, calls to repentance, and promises of future restoration.
- Pre-Classical Prophets: Prophets like Elijah and Elisha, who performed dramatic acts and miracles, often interacted directly with kings but did not leave written prophecies and therefore do not have their own books in the Bible.
- Apocalyptic Prophets: Prophets like Daniel and later Zechariah, who focused on visions of the end times and cosmic events.
- Reluctant Prophets: Prophets like Jonah and Moses, who initially resisted God’s call before fulfilling their missions.
Joel’s focus on the coming Day of the Lord and the eventual restoration of God’s people through the outpouring of the Spirit (Joel 2:28-32) connects him to the future-oriented hope of other prophets, like Isaiah and Zechariah, who looked ahead to God’s ultimate plans for Israel.
The Historical Setting of Joel’s Prophecy: Judah in the Post-Exilic Period
To fully understand Joel’s message, it is important to consider the post-exilic period in Judah. After the destruction of the First Temple in 586 BCE by the Babylonians, the Jewish people were taken into exile, and their homeland was left in ruins.
The Babylonian Exile was a period of deep despair, but after roughly 70 years, a remnant of the people returned to Judah when the Persian King Cyrus allowed them to rebuild the temple and re-establish their religious practices.
After the exile, Judah was under the control of the Persian Empire. Politically, it lacked the independence it once had, and its economy was fragile, recovering from years of destruction and neglect.
The returnees faced the challenge of restoring their national identity while living under foreign rule. Spiritually, the people were in a state of renewal, but also of uncertainty. There was a renewed focus on the Torah, the rebuilding of the temple, and the re-establishment of the sacrificial system, but there were also questions about how to remain faithful to God in a rapidly changing world.
In this context, the locust plague described by Joel was devastating not just because of its economic impact, but because it threatened the already fragile spiritual and social revival taking place in Judah.
The destruction of crops meant that grain offerings (מִנְחָה, minchah) and drink offerings (נֶסֶךְ, nesekh) in the temple could not be performed, symbolizing both material and spiritual desolation. Joel’s prophecy, then, is not only a call for repentance but a reminder that the people’s survival and success depend on their relationship with God.
The Locust Plague: Symbol of Judgment
The locust plague that Joel describes is both a real event and a symbol of God’s judgment. The Hebrew text gives multiple names for the locusts—gazam (גָּזָם), arbeh (אַרְבֶּה), yeleq (יֶלֶק), and hasil (חָסִיל)—representing different stages of destruction. These terms emphasize the completeness of the devastation, where nothing is left untouched:
“What the locust (גָּזָם, gazam) left, the swarming locust (אַרְבֶּה, arbeh) has eaten; and what the swarming locust has left, canker-worm (יֶלֶק, yeleq) has eaten; and what the canker-worm has left, the caterpillar (חָסִיל, hasil) has eaten”
Joel 1:4 tlv
These terms describe different stages or types of destructive insects, but they are often collectively referred to as locusts in other translations because they represent the same kind of devastation.
In Hebrew poetry and prophecy, using multiple words to describe a single event emphasizes its severity. Even though these words don’t all strictly mean “locusts” in a biological sense, they are interpreted this way because locusts were a well-known symbol of widespread destruction.
The focus in Joel is less about distinguishing the exact species and more about conveying the total and repeated devastation, which is why translations and commentaries often summarize them as “locusts.”
This multi-layered destruction serves as a wake-up call for the people of Judah. Joel uses this imagery to illustrate the urgency of the situation—what began as a physical disaster also pointed to a deeper spiritual crisis. The devastation of the land and the cessation of temple offerings meant that the very heart of Judah’s relationship with God was in jeopardy.
Joel’s Prophetic Message: A Call to Repentance
Unlike many of the other prophets, Joel does not accuse the people of specific sins. Instead, he focuses on the larger need for teshuvah (תְּשׁוּבָה, repentance). The calamity of the locust plague is a call for the people to return to God with all their hearts:
“Yet even now”—says GOD—
Joel 2:12-13 jps tanakh
“Turn back to Me with all your hearts,
And with fasting, weeping, and lamenting.”
This emphasis on internal repentance—”rending the heart”—is key to Joel’s message.
The people must turn back to God, not just through outward signs of grief like tearing their clothes, but through a sincere change of heart. Joel reminds the people of God’s compassionate nature, echoing earlier scriptures like Exodus 34:6-7.
“For He is gracious and compassionate,
joel 2:13 tlv
slow to anger, abundant in mercy,
and relenting about the calamity due.”
Here, Joel’s message is one of hope: if the people truly repent, God will show mercy and restore them.
The Day of the Lord: Judgment and Restoration
A central theme in Joel’s prophecy is the Day of the Lord (יוֹם יְהוָה, Yom Adonai), a time of divine intervention in human history.
Joel describes this day as a time of darkness, gloom, and destruction (Joel 2:2), when an invading army—often interpreted as either more locusts or an actual military force—will devastate the land. However, for those who repent, this day will also bring salvation and restoration.
After calling the people to fast and repent, Joel speaks of God’s promise to restore the land and bless the people once again:
““I will repay you for the years
Joel 2:25 jps tanakh
Consumed by swarms and hoppers,
By grubs and locusts,
The great army I let loose against you.”
This is one of the most hopeful passages in Joel’s prophecy. Even after such immense destruction, God promises to renew the land and the people’s relationship with Him.
Joel ends with the promise of an even greater gift: the outpouring of the Spirit on all people (Joel 3:1-5*), signaling a new era in God’s relationship with His people.
“So it will be afterward,
Joel 3:1 tlv
I will pour out My Ruach on all flesh”
The Locusts in Joel Compared to Other Biblical Accounts
Locusts in Joel
The locusts in Joel are presented as both real and symbolic. They represent a natural disaster that wreaks havoc on the land, but they also serve as a metaphor for God’s judgment. In Joel’s vision, the locusts symbolize the Day of the Lord—a warning that, just as the locusts have devastated Judah, God’s judgment will come upon all who fail to repent.
Locusts in Revelation
A strikingly different portrayal of locusts appears in the Book of Revelation (Revelation 9:1-11). Here, the locusts are supernatural creatures that emerge from the abyss, not to destroy crops, but to torment people who do not have the seal of God on their foreheads. These locusts, with their terrifying appearance—faces like humans, crowns of gold, and tails with stingers like scorpions—are agents of divine punishment in the end times.
While the locusts in Joel represent divine judgment through natural disaster, the locusts in Revelation symbolize a more apocalyptic form of punishment, meant to inflict suffering on the unrepentant. Both accounts use locusts as instruments of God’s wrath, but in very different contexts.
Locusts in Exodus
Locusts also appear in the Book of Exodus, where they are one of the ten plagues sent by God to punish Egypt (Exodus 10:12-15). These locusts, like those in Joel, are real insects that devastate the land, eating every green thing left after the previous plagues. In both Exodus and Joel, the locusts serve as a sign of God’s power and a call to repentance—whether directed at Pharaoh in Egypt or the people of Judah.
The Social and Political Impact of the Locust Plague
The locust plague in Joel’s time had far-reaching social and political consequences. In an agrarian society like Judah, the destruction of crops meant economic collapse and widespread famine. Without grain or wine, the people were not only starving but also unable to perform the required sacrifices at the temple. This deepened the spiritual crisis, as the temple worship that was central to Judah’s relationship with God had come to a halt.
Additionally, as I mentioned earlier, the political situation in post-exilic Judah was unstable. The people were under Persian rule and lacked the autonomy they once had. The locust plague would have heightened their sense of vulnerability, reminding them that their survival depended not on their own strength, but on their faithfulness to God.
Lessons from the Locust Plague and the Day of the Lord
As we have seen, the locust plague in Joel is a powerful metaphor for the consequences of turning away from God. It reminds us that while disasters may be devastating, they can also serve as wake-up calls, urging us to reflect on our relationship with God.
Joel’s message of repentance, combined with the hope of restoration, is timeless. Just as the people of Judah were called to return to God with sincere hearts, we are also called to examine our own lives and seek God’s mercy.
The Day of the Lord, as described by Joel, is both a warning and a promise. For those who continue to live in disobedience, it will be a day of judgment. But for those who repent, it will be a time of salvation and blessing.
My Final Thoughts: A Timeless Call to Repentance and Renewal
The Book of Joel speaks across the centuries with its powerful themes of judgment, repentance, and restoration. The locust plague that devastated Judah serves as a metaphor for the Day of the Lord, reminding us of the seriousness of turning away from God. Yet, Joel’s prophecy also offers hope: for those who repent, God promises restoration and the outpouring of His Spirit.
As we reflect on Joel’s message, we are reminded of the importance of staying faithful to God, even in the face of disaster. The locusts in Joel, like those in Revelation and Exodus, serve as a warning of God’s judgment but also point to the hope of renewal for those who turn back to Him.

*The difference in verse numbering between Joel 2:28 and Joel 3:1 in some translations is because of how Hebrew Bibles and Christian Bibles divide the chapters. In the Hebrew Bible, the verse about God pouring out His Spirit is part of chapter 2. In many Christian Bibles, influenced by older translations like the Septuagint, the same verse is placed at the start of chapter 3. The text is the same, but the chapter breaks are different due to how ancient scholars organized the sections.
