This research evaluates the role of the Book of Micah in the global structure of the Book of the Twelve, especially Micah s theological aspect. Its purpose is to analyze the inter-relationship between the Book of Micah 7,8-20 and other prophetical texts, in an effort to determine how each of the prophets contributed with specific points for a greater interest. The purpose is to examine the final text of the Book of the Micah, evaluating how the literary structure was formed in order to conclude the Book. Present investigations indicate that the horizon of the prophetical scriptures is not limited to the respective prophetic Book, but that the complementary elements stretch out beyond the Book itself. The title of this work should be understood under this aspect. In this way, besides shedding light on the problematic of this unity of the Twelve Prophets, this work aims at better understanding of the development, the unit and the theology of the Twelve Minor Prophets, and particularly the Book of Micah.
