The volume is a commentary on 1 Enoch chapters 91–108 that begins with the Ethiopic text tradition but also takes the Greek and Aramaic (Dead Sea Scrolls) evidence into account. This section of 1 Enoch, most of which contains material from documents composed during the 2nd century BCE, provides a window into the early stages of the reception of the earliest Enoch tradition as it was being negotiated in relation to elitist religious opponents and in relation to other Jewish traditions that were flourishing at the time.
