Probably more commentaries, study guides, and helps have been published on the book of Psalms than on any other book of the Bible. It is not my purpose here to supplant those other works. Rather, I want to offer some suggestions to the Christian on how to use the Psalms so that he can then more profitably use these other works on the Psalms.
The Psalms themselves were written throughout the entire period of Old Testament revelation, from the time of Moses (Psalm 90) to the period after the exile (Psalm 126). The titles of seventy-two psalms ascribe them to David, while others are by Solomon, Asaph, Heman, and the sons of Korah. Some of the psalms may have been used in temple worship (hence the phrase “to the choirmaster” in more than fifty psalm titles). The psalms are of different types. Some are laments, both individual (Psalm 42) and corporate (Psalm 44). Some are psalms of thanksgiving (Psalm 100), while others are hymns, or songs of praise (Psalm 96). Some of the psalms are commonly referred to today as “wisdom” psalms, such as Psalms 1 and 119. These psalms tend to be reflections on the Word of God. Some psalms, such as Psalms 69 and 109 are referred to as “imprecatory” psalms, in which the substance of the psalm is a prayer against the enemies of God (an imprecation).
