Joel opens in crisis. A locust swarm of unprecedented scale has stripped the land bare — vines, fig trees, grain, orchards — and in the silence left behind, the prophet hears not merely an agricultural disaster but a theological summons. The plague is real: the elders have never seen anything like it, and they are told to tell their children, who must tell theirs (1:2–3). But the plague is also a sign, a rehearsal for something larger — the Yom YHWH, the Day of the LORD, toward which all of Joel's preaching is oriented.
Joel 1–2:17
Locust Plague and the Day of the LORD
Main Highlights
- A catastrophic locust plague strips every sector of Judean life bare, and Joel summons every group — drunkards, priests, farmers — to corporate lament.
- The locusts are recast in military terms as a divine army heralding the cosmic Day of the LORD, deliberately escalating beyond any natural event.
- God calls Israel to "rend your hearts and not your garments," insisting that inward repentance must precede outward ritual.
- The summons to return is grounded not in Israel's moral capacity but in God's known character from Exodus 34:6 — gracious, merciful, abounding in steadfast love.
The Devastation Described
Joel 1 calls every sector of society to mourn. The drunkards are told to wake and weep — the grapevines are destroyed and the new wine is cut off (1:5). The priests are summoned to lament because grain offerings and drink offerings have ceased at the house of God (1:9). The farmers and vinedressers are called to wail because the harvest has perished (1:11). No one escapes the reach of the plague; no one is too wealthy or too poor to feel it.
John Barton, in his Joel and Obadiah commentary (OTL, 2001), notes the careful literary structure of chapter 1 — the repeated calls to lament addressed to different groups function as a kind of liturgical assembly, gathering the entire community into a posture of corporate grief. The plague, Barton argues, is not simply being lamented as a natural tragedy. It is being interpreted: this is not random misfortune but an act that demands theological attention, a moment when the community must look up from its suffering and ask what God may be saying.
The imagery is visceral. Joel reaches for the language of a young woman clothed in sackcloth grieving the husband of her youth — a mourning image that places the tragedy in the register of personal bereavement, not merely economic loss (1:8). Even the beasts of the field are said to pant toward God because the water brooks are dry (1:20). Creation itself groans. Leslie Allen, in The Books of Joel, Obadiah, Jonah and Micah (NICOT, 1976), observes that this widening of the lamentation to include animals and land echoes the creation theology that pervades the Hebrew imagination — when the covenant people suffer, the land suffers with them. We find that detail worth holding: the beasts panting toward God. Not just the people. Everything that breathes is caught in the same distress, and Joel says they are all, in their way, crying out.
Joel 2:1–11: The Army of the Day
Chapter 2 escalates dramatically. The locust swarm, already devastating, is now described in military terms that blur the line between historical plague and eschatological army:
"Blow a trumpet in Zion; sound an alarm on my holy mountain! Let all the inhabitants of the land tremble, for the day of the LORD is coming; it is near, a day of darkness and gloom, a day of clouds and thick darkness, like blackness there is spread upon the mountains a great and powerful people; their like has never been before, nor will be again after them through the years of all generations." — Joel 2:1–2 (ESV)
The Yom YHWH (יוֹם יְהוָה) — the Day of the LORD — is one of the most significant theological concepts in the prophetic literature. In pre-exilic popular expectation, many Israelites assumed the Day of the LORD would be a day of triumph for Israel over its enemies. Amos had already subverted this assumption (Amos 5:18–20), and Joel carries the subversion further: the terrible army descends not on Judah's enemies but on Judah itself. The locusts become warriors; they scale walls and climb into houses; nothing stops them (2:7–9). Before them the earth quakes, the sun and moon are darkened, the stars withdraw (2:10–11).
Barton notes that the prophet deliberately refuses to finally identify this army as either literal locusts or a foreign military force — the ambiguity is theological, not accidental. The Day of the LORD uses the instruments of history and nature as its agents, and Joel places the reader in the frightening position of seeing the present catastrophe as a foretaste of what unchecked divine judgment would look like on a cosmic scale. What strikes us is how deliberately the description escalates beyond what any locust plague could do — the darkening of the sun, the stars withdrawing. Joel is using the present disaster to crack open something larger. The local catastrophe becomes a window into the ultimate one. That layering is unusual and unsettling in the best way.
Joel 2:12–17: The Call to Return
Here the tone pivots. After ten verses of terrifying military imagery, God speaks directly:
"'Yet even now,' declares the LORD, 'return to me with all your heart, with fasting, with weeping, and with mourning; and rend your hearts and not your garments.' Return to the LORD your God, for he is gracious and merciful, slow to anger, and abounding in steadfast love; and he relents over disaster." — Joel 2:12–13 (ESV)
The phrase "rend your hearts and not your garments" is one of the most memorable lines in the Minor Prophets. Tearing one's garments was the standard outward sign of grief and repentance in ancient Israel. Joel does not forbid the external act — he insists that the internal reality must match it. David Baker, in Joel, Obadiah, Malachi (NIVAC, 2006), points out that the call is saturated with the language of Exodus 34:6, the great self-disclosure of God after the golden calf: "gracious and merciful, slow to anger, and abounding in steadfast love." Joel's summons to repentance is anchored not in Israel's moral capacity but in God's known character. The reason to turn back is not that Judah has earned another chance but that God has always been this kind of God.
The section closes with the priests weeping between the porch and the altar, crying: "Spare your people, O LORD, and make not your heritage a reproach, a byword among the nations" (2:17). The question mark hangs over everything: "Who knows whether he will not turn and relent, and leave a blessing behind him?" (2:14). The answer is not presumed — it is hoped for, on the basis of who God has shown himself to be. "Rend your hearts and not your garments" — that line stops us every time. It's not saying external mourning is meaningless. It's saying the inside has to go first. That remains a harder ask than any ritual.
