Joel

Overview

Joel is one of the Twelve Minor Prophets in the Hebrew Bible and Old Testament. Beyond the superscription, which names him "the son of Pethuel" (Joel 1:1), no secure biographical data are supplied, and the book itself offers few historical markers by which his date can be fixed with confidence. For that reason Joel has been one of the more debated prophetic books with respect to historical setting, with proposals ranging from the ninth century BCE to the Persian period. The prophet addresses Judah and Jerusalem, interprets an overwhelming locust plague and drought as a theological summons to repentance, and announces the coming "day of the Lord" as both judgment and eventual deliverance. Joel's reception has been especially significant in Jewish liturgical and prophetic reading and in Christian interpretation because Acts 2:16-21 cites Joel 2:28-32 (Hebrew 3:1-5) in connection with the outpouring of the Spirit at Pentecost.

Biblical shape

Prophet of Judah; attributed author and speaking voice of the Book of Joel. Prophetic superscription: The book opens by identifying the prophetic word as coming to Joel, son of Pethuel, which is the only explicit personal notice about him. Interpretation of the locust plague and drought: Joel summons elders, priests, farmers, and the whole land to lament a devastating ecological catastrophe, reading it as a crisis that demands communal mourning, fasting, and return to God. Call to repentance and announcement of the day of the Lord: The prophet sounds alarm in Zion, depicts the terrifying nearness of the day of the Lord, and urges repentance marked by torn hearts rather than merely torn garments. Promise of restoration: Following repentance, the Lord is portrayed as answering with pity, restoring agricultural abundance, removing shame, and renewing the covenant bond with the people. Outpouring of the Spirit: Joel announces that God will pour out the divine Spirit on "all flesh," extending prophetic gifting beyond traditional social boundaries to sons and daughters, old and young, male and female slaves.

Theological significance

In the book of Joel itself, the prophet is introduced only as “the son of Pethuel” (Joel 1:1), and his message interprets locust devastation and drought as a summons to repentance before the coming “day of the Lord,” followed by renewal and outpoured Spirit. In Second Temple and early Christian reception, Joel’s oracle became especially prominent through Acts 2:16–21, where Peter applies Joel 2:28–32 to Pentecost. Origen treated Joel as a prophetic witness to divine judgment and restoration, while Jerome, in his Commentarii in XII Prophetas Minores, emphasized the book’s penitential force and its eschatological horizon; Augustine cited Joel chiefly in relation to the Spirit and the church’s last things. In the medieval period, John of Damascus used Joel in his defense of the Spirit’s work, and later commentators read the book through the liturgical pattern of fasting, lament, and hope. Ecumenical Consensus: Jewish and Christian interpreters broadly agree that Joel is a prophet associated with Judah and Jerusalem whose book centers on calamity, repentance, the day of the Lord, and restoration.
