Job, Ecclesiastes, Song of Songs (Cornerstone Biblical Commentary, Vol. 6):

The Cornerstone Biblical Commentary series (18 volumes) is the product of nearly 40 scholars, many of whom participated in the creation of the NLT. The contributors to this series, who are well-known and represent a wide spectrum of theological positions within the evangelical community, have built each volume to help pastors, teachers, and students of the Bible understand every thought contained in the Bible. In short, this will be one of the premier resources for those seeking an accessible but fairly high-level discussion of scriptural interpretation.
