What is Joel about?

Joel opens with a disaster: wave after wave of locusts has stripped the fields, vines and fig trees, and drought has followed. Grain and drink offerings at the temple have stopped. Joel calls elders, farmers, priests and everyone else to mourn and cry out to God.

The prophet sees in the locusts a preview of something greater, the Day of the LORD, pictured as an invading army darkening the sky. But the warning leads to an invitation: tear your hearts, not your garments, and return to a God who is gracious and compassionate. When the people respond, God promises to restore what the locusts ate.

The final part looks further ahead. God will pour out his Spirit on all flesh, sons and daughters, old and young, servants included. The nations will be judged in the Valley of Jehoshaphat, and Judah and Jerusalem will be secure, with God dwelling in Zion.

Key themes

  • The Day of the LORD. This phrase is at the centre of Joel's message: a day of judgment on sin, but also the day God sets the world right.
  • Wholehearted repentance. God wants changed hearts, not just outward rituals. He is gracious, slow to anger and abounding in love (Joel 2:13), echoing God's self-description to Moses.
  • Restoration. God promises to repay the years the locusts ate, a message many readers take to heart after seasons of loss.
  • The Spirit for everyone. Joel foresees God's Spirit given not only to prophets or kings but to all his people, regardless of age, gender or status.

Key people and places

  • Joel — Prophet, son of Pethuel; otherwise unknown.
  • Priests and elders — Leaders called to gather the people in repentance.

Key verses in Joel

Quoted from the Berean Standard Bible (BSB).

““Yet even now,” declares the LORD, “return to Me with all your heart, with fasting, weeping, and mourning.” So rend your hearts and not your garments, and return to the LORD your God. For He is gracious and compassionate, slow to anger, abounding in loving devotion. And He relents from sending disaster.”

Joel 2:12-13BSB

Return with all your heart; tear your heart, not your clothes.

“I will repay you for the years eaten by locusts— the swarming locust, the young locust, the destroying locust, and the devouring locust — My great army that I sent against you.”

Joel 2:25BSB

God will repay the years the locusts have eaten.

“And afterward, I will pour out My Spirit on all people. Your sons and daughters will prophesy, your old men will dream dreams, your young men will see visions. Even on My menservants and maidservants, I will pour out My Spirit in those days.”

Joel 2:28-29BSB

God's Spirit poured out on all people; quoted by Peter at Pentecost.

“And everyone who calls on the name of the LORD will be saved; for on Mount Zion and in Jerusalem there will be deliverance, as the LORD has promised, among the remnant called by the LORD.”

Joel 2:32BSB

Everyone who calls on the name of the LORD will be saved.

How Joel fits the big story

Joel sits second among the minor prophets, between Hosea and Amos, and Joel 3:16 and Amos 1:2 share the image of the LORD roaring from Zion. The Day of the LORD theme runs through prophets like Zephaniah and Malachi. Joel's promise of the Spirit is quoted by Peter in Acts 2 to explain Pentecost, and Paul quotes Joel 2:32 in Romans 10 to show that salvation is open to everyone who calls on the Lord.

Frequently asked questions

Who wrote the book of Joel?

The book is credited to Joel son of Pethuel, but the Bible tells us nothing else about him: not his town, his king or his era. Tradition accepts him as author. Because the book gives no date, scholars disagree on when he lived, with suggestions ranging from the 9th century BC to after the exile.

How many chapters are in Joel?

In most English Bibles Joel has 3 chapters and 73 verses. Hebrew Bibles divide it into 4 chapters, so the promise of the Spirit appears as Joel 2:28–32 in English but as chapter 3 in Hebrew.

Were the locusts in Joel real?

Most readers think chapter 1 describes a real locust plague that devastated Judah. In chapter 2 the locusts become a picture of an invading army on the Day of the LORD. Some interpreters read both chapters as symbolic of foreign armies, but the plain sense of chapter 1 is an agricultural disaster.

How is Joel connected to Pentecost?

When the Holy Spirit came on Jesus' followers at Pentecost, Peter explained it by quoting Joel 2:28–32 (Acts 2:16–21). For Christians, Joel's promise of the Spirit poured out on all people began to be fulfilled that day.
