Book excerpt: Introduction to the Psalms: A Song from Ancient Israel seeks to provide the reader with a solid introduction to the Hebrew Psalter, one that is informed by an interest in its shape and shaping. The author, Nancy deClaiss�-Walford, provides an up-to-date study on the poetic style of the psalms in the Psalter, their Gatt�ngen or genres, the broad shape of the book, and the history of its shaping. She introduces each of the five books of the Psalter, providing a detailed examination of those individual psalms that are either key to the shaping of the Psalter or interesting studies in poetic style. In the final chapter, deClaiss�-Walford draws conclusions about the shape of the Psalter and about its story and message. She proposes a way to read the Psalms as a unified whole and in relationship to one another rather than as individual pieces, giving an inclusive, all-encompassing shape to the Psalter. Included are two appendices that provide a listing of the superscriptions and Gatt�ngen of the psalms in the Hebrew Psalter and an explanation of many of the technical terms found in their superscriptions.
