I was disappointed with this Commentary not so much because it was poor but because the other Commentaries I had used in this series were so excellent. It is a one volume commentary and is similar to other one volume commentaries on Psalms. I thought the Expositors commentary had more textual level comment and more homeitical material. Although it is old I found Lange's one volume on Psalms more useful for preaching as it was more personal. I only write this as a caution to others who may have found the other volumes in this series to be so excellent.
