I have several questions that perhaps someone could answer. I noticed that the Pesharim, Community Rule and Damascus Documents seem to all be written by the same group, since they refer to the Teacher. The War Scroll doesn't mention the teacher, and would appear to be written by another group, though they do mention the Kittim, which may have been a generic concept among Jews for the Romans.
Jewish tradition speaks often of lost writings and books.
I am wondering whether some of the other scrolls which do not evince sectarian beliefs may have been from those lost writings referred to in the Talmud and elsewhere. I am interested to know whether anyone has ever compared the content of these scrolls with midrashic teachings, to ascertain a commonality of origin. I look forward to all comments on my questions.
