All serious students of the Bible seek to know which resources are most valuable to add to their growing libraries. With an abundance of tools available, relative merit is difficult to ascertain, so students often turn to trusted professors for advice. This commentary survey provides such advice from respected Old Testament scholar Tremper Longman III. In this handy volume, Longman introduces the most popular commentaries on each book of the Old Testament, gives a brief indication of their emphases and viewpoints, and evaluates them. At the end of the book, he summarizes his top recommendations for those trying to build a library that covers every book of the Old Testament. For this fourth edition, Longman has added comments on the commentaries published in the years since the third edition, updated his evaluations of other commentaries in light of these new additions, and refined his rating system to provide more nuance. The result is a balanced, sensible guide for those who preach and teach the Old Testament and need help in choosing the best tools.
