The book deals with the genesis of the Book of the Four Prophets (Hosea, Amos, Micah, Zephaniah) from the time of exile, the Haggai-Zechariah-Corpus and the integration of the Book of Joel into the Book of the Four Prophets from the time of exile. In contrast to previous research, the findings are based for the first time on an analysis of the editorial history of each of the individual books. Thus it is possible to provide a precise description of the composition, intention and historical theological backgrounds of these early collections.
