The purpose of the present thesis is to investigate rhetorical features of the Book of Amos with a view to identifying the message and meaning intended by the prophet Amos in his authentic passages. The purpose is not only to identify the prophet's rhetorical goal in his ' rhetorical situation', but also ultimately to explicate the meaning of his message in his historical situation. In examining its rhetorical features, the rhetorical analysis of the present thesis attempts to clarify how the prophet Amos fabricated the text in rhetorical structures and how he built up his rhetoric to convey his message in the book. In the introduction, the thesis investigates the types of rhetorical-critical discipline which also illustrate the history of rhetorical criticism. It also raises problems in the rhetorical-critical disciplines of Old Testament studies and the Book of Amos. It suggests the four steps of rhetorical analysis as its method of approach. Those consist of the investigations of: 1) the rhetorical structures(syntactic and syntagmatic, and mimetic dimension), 2) literary functions (semantic dimension), 3) rhetorical functions ( ':Message-Analysis'; pragmatic dimension), and 4) rhetorical natures(syntactic and syntagmatic, linear compositional macro-structural dimension), in the rhetorical units of the book of Amos. It also suggests that the book is divided into the four literary/rhetorical units; chs.1-2, 3-4, 5-6, and 7-9. In order to identify the message and meaning of the Book of Amos in his rhetorical and historical situation, the third and fourth steps investigate the prophet's rhetorical strategies through which he intended to pursue an effective conveying of his message in the Book of Amos. Of the two, the fourth step, in particular, attempts to identify how Amos designed the sections and subsections to perform rhetorical functions in the macro-structure of the book, and how he fabricated the text with the elements, according to their 'rhetorical natures' in the text, i.e., 'rhetorical sections' and 'message-sections.' For this purpose, chapter 2 of the thesis establishes the criteria through verifying their validity in the Minor Prophets. The thesis demonstrates, through the four-step rhetorical analysis, that chs.5-6 are designed to function as the 'message-section' of the book on which Amos intended to lay more emphasis than on other sections in formulating his message. The three other sections, chs. 1-2, 3-4, 7-9, are designed to function as the ' rhetorical sections', which are used for forming the framework of his rhetoric in the pursuit of the effective conveying of his message. The thesis suggests that the prophet pursued his rhetorical goal in resolving or modifying the historical exigence of social disorder caused by the perversion of justice in which his prophetic task emerged. Hence, it proposes as its conclusion that, in performing his prophetic task to deliver the message through drawing a rhetorical impact upon the audience in the pragmatic dimension. he encouraged the audience to take action for the resolution or modification of the historical exigence in his historical rhetorical situation, particularly by giving the exhortations to justice as 'the primary Message' (5:4-6, 14-15, and 24) in 'the message-section' (chs.5-6).
