The commentary includes discussion throughout of three primary challenges to understanding the Psalms:
- Textual issues: Every major textual difficulty is addressed in order to help the expositor understand the interpretive issues and make decisions when there are multiple available readings.
- Poetic language: The Psalms are full of poetic imagery, devices and structures. Ross discusses this "language" of Hebrew poetry in its context with each psalm, specifying the precise devices being used and how they work in the psalm.
- The Psalms' Hebrew grammar and syntax pose a challenge to many expositors, whether they are familiar with Hebrew or not. This commentary illuminates Hebrew constructions word meanings in a way that is helpful both to readers who are comfortable with Hebrew and those who are not.
