Kessler's erudite book aims to prove not only that exegetical encounters occurred between the ancient rabbis and the early church fathers in both directions, but also that “to understand properly Jewish or Christian exegesis in late antiquity it is essential to understand each other's interpretations and the influence of one upon the other” (182). He begins by reviewing the shortcomings of previous approaches to Jewish–Christian interaction in late antiquity. Kessler then puts forward what he terms the exegetical approach, suggests some controls on this method, and proceeds to test his hypothesis by conducting a verse-by-verse examination of Genesis 22. In each chapter, he first surveys a few major early interpreters, such as Philo and Josephus, and then compares Rabbinic and early Christian interpretations on Genesis 22 in some detail. There is also a final chapter that examines ancient artistic renderings of Abraham's near sacrifice of Isaac.
