The psalms have been central to Jewish and Christian and spirituality across the centuries. In them people of all times and places have found echoes of their own experiences, whether of praise or perplexity, certainly or doubt, quiet assurance or agonized questioning. This commentary on the book of Psalms by Robert Davidson seeks to show how a knowledge of the place the psalms originally had in the worship of ancient Israel enables them to come alive in worship within believing communities today. Taking primarily a theological approach to the psalms, Davidson looks at each numbered psalm in turn, discussing its relationship to the other psalms, its message according to its original context, and its enduring theological significance. Davidson's special concern to highlight the continuing relevance of the Psalms for worship also contributes greatly to our understanding of the vitality and richness of worship in ancient times and now. According to Davidson, when we recognize in the psalms their reflection of our own life experiences, they can be significantly more helpful to our private spiritual lives and our public worship that many of the hymnbooks currently being used.
