This is a commentary and guide to reading the Book of Psalms as literature. After an introduction, each psalm is interpreted in light of biblical scholarship, ancient and modern, with an emphasis on the poetic presentation. The commentary elucidates the spiritual quests, insights, and struggles of generations of men and women confronting their world and their place in that world, with no subject, be it faith or non-belief, good or evil, hope or despair, God or man, the individual or the society, the nation or the nations, left unexplored. Sophisticated poets who knew how to speak to both their peers and the masses, the psalmists used words creatively to allow their readers to search their own hearts. The words are ancient, but the questions are immediate and modern. The Psalms has contributed to the thinking and search of people across the millennia. It is truly poetry of the heart. In this commentary, modern research and insight allow the poems to sing once again. No other commentary brings a combination of classical and modern interpretations to the Book of Psalms, along with a real appreciation for the poetic skills of the poets and an acknowledgement of their own struggles and strivings. Uniquely identifying the literary techniques used by the psalmist, the author opens the psalms to the reader through an integrated appreciation of form and content.
