📖 Biblical Definition
The second of the twelve Minor Prophets, a short three-chapter prophecy reading a devastating locust invasion of Judah as a sign of the coming Day of the LORD. Joel's date is debated — proposals range from the pre-exilic ninth century to the post-exilic fifth century. The book's structure: (1) chapter 1 describes the locust devastation; (2) chapter 2 amplifies the locusts into the eschatological day of judgment, calls Israel to repentance, and promises the Spirit's outpouring on all flesh; (3) chapter 3 (Hebrew 4) narrates the final judgment of the nations and the restoration of Judah. Joel 2:28-32 is the canonical Pentecost prophecy: And it shall come to pass afterward, that I will pour out my spirit upon all flesh; and your sons and your daughters shall prophesy, your old men shall dream dreams, your young men shall see visions. Peter explicitly cited this passage at Pentecost (Acts 2:16-21) as the inaugurating fulfillment of Joel's promise. The locusts that ravaged ancient Judah became the typological signal of the Spirit-poured-out age.

Peter quoted Joel 2 on the day of Pentecost — and the church has been quoting Peter quoting Joel ever since, while never reading the chapter that comes before. Joel begins with locusts, fasting, and torn hearts. The Spirit falls on the prepared, not the casual.
The promise of restoration — 'I will restore the years the locust has eaten' — is one of the tenderest in Scripture. God does not deny the locust; He outstrips it. But restoration follows return; the order matters.
