sn The dating of the book of Joel is a matter of dispute. Some scholars date the book as early as the ninth century b.c., during the reign of the boy-king Joash. This view is largely based on the following factors: an argument from silence (e.g., the book of Joel does not mention a king, perhaps because other officials de facto carried out his responsibilities, and there is no direct mention in the book of such later Israelite enemies as the Assyrians, Babylonians, and Persians); inconclusive literary assumptions (e.g., the eighth-century prophet Amos in Amos 9:13 alludes to Joel 3:18); the canonical position of the book (i.e., it is the second book of the Minor Prophets); and literary style (i.e., the book is thought to differ in style from the postexilic prophetic writings). While such an early date for the book is not impossible, none of the arguments used to support it is compelling. Later dates for the book that have been defended by various scholars are, for example, the late seventh century or early sixth century or sometime in the postexilic period (anytime from late sixth century to late fourth century). Most modern scholars seem to date the book of Joel sometime between 400 and 350 b.c. For a helpful discussion of date see J. A. Thompson, “The Date of the Book of Joel,” A Light unto My Path, 453–64. Related to the question of date is a major exegetical issue: Is the army of chapter two to be understood figuratively as describing the locust invasion of chapter one, or is the topic of chapter two an invasion of human armies, either the Babylonians or an eschatological foe? If the enemy could be conclusively identified as the Babylonians, for example, this would support a sixth-century date for the book.
