Individual psalms are treated in one of two ways: either in a concise, descriptive fashion or in the form of expository essays. Those receiving fuller treatment consist of psalms that are prominent in the practice of worship, those that are used in the New Testament, those that are most important to the theology of the church, and those that shed the most light on the Psalter as a whole.
