This sounds like a very interesting book. But, and I keep saying this, the Greek Testaments of the Twelve Patriarchs is a second-century Christian work. True, in some cases it is based on Jewish material, verifiably mainly in the Testament of Levi and the Testament of Naphtali. But it is poor methodology to use the whole thing as testimony to Hellenistic Judaism.
Similarly, the Testament of Job is often assumed to be a Hellenistic Jewish work. But I have explained here why this assumption is methodologically weak.
But most of the material covered in this book is relevant to the topic, and the topic is certainly worthwhile.
