The book of Isaiah is a composite work whose formation took place over a long period of time, incorporating the work of many different hands rather than the work of a single author. A crucial stage in this process came with the Jewish return from Babylonian exile, and the subsequent efforts at restoration. In this new context, how were the older Isaianic oracles to be seen? What did they say? examines this question in depth from the point of view of the book's formation. Jacob Stromberg illuminates the textual hermeneutics embedded in the post-exilic shape of Isaiah, contributing to our understanding of the dynamics of scriptural formation in this influential period of Jewish history. The author of Third Isaiah is shown to have edited the book in line with his reading of it to project the old word into the new post-exilic situation. Stromberg unfolds this argument in three parts. The first defines Third Isaiah's final form, finding the work of its author especially in its 'frame' (56.1-8; 65-66). The second part analyzes this 'frame' for references to earlier Isaianic oracles, uncovering allusions to older material from throughout the book. A portrait emerges of the author of Third Isaiah as a reader of the book, providing an important key to unlock the door on his work as a redactor - the premise being that his hermeneutics as a reader would inevitably reflect his hermeneutics as a redactor. Working in the light of this portrait, the third part examines the author of Third Isaiah as a redactor of the book, uncovering several examples throughout Isaiah where probability seems to favor this hand at work.
