Despite renewed interest in the book of Joel and its relationship to the “Book of the Twelve,” scholarly opinions still significantly diverge on the structure of the book of Joel itself. This article surveys recent significant and representative proposals for Joel’s structure before arguing for an alternative unified structure based upon grammar, literary markers or “catchwords”, and structural relationships (according to David R. Bauer and Robert A. Traina, Inductive Bible Study).
