In this innovative study, a different approach to the study of the Psalms from that represented by form criticism is attempted. What is determinative here is the context given to the psalms in their positions in the Psalter: that is, the collections in which they are gathered, the order in which they stand, and the technical notes (Maskil, Selah, and the like) in the text. The application of this approach to one group of psalms, the psalms of the sons of Korah (42-49, 84-85, 87-88 + 89), results in the theory, developed with the author's characteristic flair and originality, that the Korah psalms stand in their original order as the liturgy of the national festival at the Danite sanctuary. Its many fresh and persuasive exegetical suggestions make this work an essential acquisition for the student of the Psalter.
