"What is the "way of the LORD" in the book of Isaiah? Many scholars have adopted Walter Zimmerli's proposal that the "way" in Second Isaiah is a literal and physical highway extending from Babylon to Jerusalem only to be reinterpreted as a spiritual, metaphorical, and pious way of living in Third Isaiah. This book will properly define each mention of the "way" in Isaiah as well as provide a coherent interpretation of this theme's theological significance within the book. The way of the LORD is initially conceived of in the 1 st half of the book as a highway leading to Zion common to both the dispersed Israelites as well as the nations. In Isaiah, Chs 34-35 provide a paradigm of what this way will entail and its theological significance. "

"[T]his book is the result of thorough research with a logical and systematic treatment of the theme of “the way of the LORD” throughout the book of Isaiah. Lim’s book should be on the shelves not only of people interested in the book of Isaiah but also of those working on the prophetic literature of the Old Testament generally." - Review of Biblical Literature
