The Book of Joel is a Jewish prophetic text containing a series of "divine announcements". The first line attributes authorship to "Joel the son of Pethuel". It forms part of the Book of the twelve minor prophets or the Nevi'im ("Prophets") in the Hebrew Bible, and is a book in its own right in the Christian Old Testament. Joel is not mentioned elsewhere in either collection. The original text was written in Hebrew language. Some early manuscripts containing the text of this book in Hebrew are of the Masoretic Text tradition, which includes the Codex Cairensis (895 CE), the Petersburg Codex of the Prophets (916), Aleppo Codex (10th century), Codex Leningradensis (1008). Fragments containing parts of this book in Hebrew were found among the Dead Sea Scrolls, including 4Q78 (4QXIIc; 75–50 BCE) with extant verses 1:10–20, 2:1, 2:8–23, and 3:6–21; and 4Q82 (4QXIIg; 25 BCE) with extant verses 1:12–14, 2:2–13, 3:4–9, 3:11–14, 3:17, 3:19–2; Schøyen MS 4612/1 (DSS F.117; DSS F.Joel1; 50–68 CE) with extant verses 3:1–4); and Wadi Murabba'at Minor Prophets (Mur88; MurXIIProph; 75–100 CE) with extant verses 2:20, 2:26–27, 2:28–32, and 3:1–16. Ancient manuscripts in Koine Greek containing this book are mainly of the Septuagint version, including Codex Vaticanus (B; B; 4th century), Codex Sinaiticus (S; BHK: S; 4th century), Codex Alexandrinus (A; A; 5th century) and Codex Marchalianus (Q; Q; 6th century). After the initial attribution, the book may be broken down into the following sections: Lament over a great locust plague and a severe drought (1:1–2:17). The effects of these events on agriculture, farmers, and on the supply of agricultural offerings for the Temple in Jerusalem, interspersed with a call to national lament (1:1–20). A more apocalyptic passage comparing the locusts to an army, and revealing that they are God's army (2:1–11). A call to national repentance in the face of God's judgment (2:12–17). Promise of future blessings (2:18–32 or 2:18–3:5). Banishment of the locusts and restoration of agricultural productivity as a divine response to national penitence (2:18–27).
