Knibb provides fresh translations of substantial extracts from the Qumran writings together with an exegetical commentary to create a source book for the study of the Qumran community. Each piece has been carefully selected; instead of presenting a large number of isolated scraps, Knibb limits his choices to the several more impressive tracts. The great importance of this book lies in the exegetical commentary that confronts interpretative problems raised by each of the writings translated here.
