In "Isaiah Old and New," Ben Witherington III embarks on a scholarly journey that bridges the ancient and the ever-evolving interpretations of the Book of Isaiah. With meticulous care, Witherington peels back the layers of historical context and textual analysis to reveal Isaiah not just as a cornerstone of Old Testament prophecy, but as a living document that resonates through the New Testament and beyond. This work is not merely an academic exercise; it is an invitation to explore the dynamic interplay between the original messages of Isaiah and their subsequent reimaginings and reinterpretations in the early Christian era. Witherington combines the rigor of a seasoned theologian with the accessibility of a gifted teacher, making "Isaiah Old and New" an indispensable resource for pastors, educators, and students alike. His approach of reading "forward and backward" opens new vistas for understanding biblical intertextuality, offering fresh insights into how sacred texts converse across time. This book is a testament to the enduring power of Isaiah, challenging and enriching its readers to appreciate the depth and breadth of its influence on Christian thought and theology.
