I tried reading books about the DDS as i was fascinated by the traveling display of the DDS in the USA. We got to see it in a city near us. Lots of JWs went to see the display when it came. By that time, I was well into the books and knew a considerable more info than the "friends" who's main interest was to locate Jah's name. I remember offering some things to look for, and I'm afraid it was too much info for them to handle.
I thought it interesting that the Qumran community was so monastic and determined to present themselves pure in body and spirit. They were all things communal. If you fell out of favor with the community, you could and would likely starve to death. Their location was close to the Jordan where John did his baptising, which for me was sort of a revelation. Like..why baptism? Where did that concept begin? While I'm not certain of the conclusion, that community at Qumran ceremoniously bathed several times a day. The Essenes were another faction of the Jews along with the Pharisees and Sadducees. They felt the existing priesthood in Jerusalem was illegitimate and were openly critical of it. Knowing the background of these sects helps when reading the words of Jesus and his apostles. Particularly in Jesus case, as he had to always consider his audience's background. Lots more to know about their (DDS) existence.
The 2 books that were helpful for me: "The Dead Sea Scrolls and the First Christians" - Robert Eiseman and "The Dead Sea Scrolls: The Truth Behind The Mystique" - Lawrence A. Schiffman (this is available in 7 CDs incorporating 14 lectures) He's very animated. Listened as I drove around during business day. Understanding that period and the Maccabees era is a great help in putting puzzle parts together re: what Jesus had to deal with, and years later when decisions were made re: the Bible canon. Good background!
