Sigmund Mowinckel is widely recognized as one of the leading forces in Psalms research during the twentieth century. Indeed, the culmination of Mowinckel’s thought and work, The Psalms in Israel’s Worship, continues to play a significant role in Psalms scholarship today. Not as well known are the seminal studies that prepared the ground for Mowinckel’s later work, the six Psalmenstudien that are translated here into English for the first time. In these studies Mowinckel explores with care and in detail such topics as: “'Awen and the Psalms of Individual Lament”; “YHWH’s Enthronement Festival and the Origin of Eschatology”; “Cultic Prophecy and Prophetic Psalms”; “The Technical Terms in the Psalm Superscriptions”; “Blessing and Curse in Israel’s Cult and Psalmody”; and “The Psalmists.” Anyone interested in Psalms study, especially the possible role of the New Year’s enthronement festival within Israel’s cult and its relation to the Psalter, will find much to consider in these classic works.
