The volume provides exegetical and critical study of Israelite wisdom literature, focusing on Job and Ecclesiastes while also examining Proverbs and Ecclesiasticus. It offers chapter-by-chapter commentary on Job’s dialogue cycles, Elihu’s speeches, the divine speeches and the epilogue, and assesses traditional bases, date, and mythological and angelological material. It analyzes the form, origin, collections, and religious value of Proverbs, and presents Sirach’s moral teaching alongside Kohelet’s skeptical reflections, practical counsels, and textual questions. Philological appendices, discussion of the Septuagint, and student aids complete the work.
