Isaiah 1-39, by Marvin A. Sweeney, is volume xvi of the forms of the Old Testament Literature, a series that aims to present a form-critical analysis of every book each unit in the Hebrew Bible. Fundamentally exegetical, the FOTL volumes examines the structure, genre, setting and intention of the biblical literature in question. They also study the history behind the form-critical discussion of the material, attempt to bring consistency to the terminology for the genres and formulas of the biblical literature, and expose the exegetical procedure so as to enable students and pastors to engage in their own analysis and interpretation of the Old Testament texts.
