Kipp Davis (‪@DrKippDavis‬) is a post-doctoral fellow at the University of Agder in Kristiansand, Norway, where he specialises in the assignment and reconstruction of fragments from the Dead Sea Scrolls and their interpretation. (Google Books)

The Dead Sea Scrolls are a set of ancient Jewish manuscripts from the Second Temple period. They were discovered over a period of 10 years, between 1946 and 1956, at the Qumran Caves near Ein Feshkha in the West Bank, on the northern shore of the Dead Sea. Dating from the 3rd century BCE to the 1st century CE, the Dead Sea Scrolls include the oldest surviving manuscripts of entire books later included in the biblical canons, including deuterocanonical manuscripts from late Second Temple Judaism and extrabiblical books. At the same time, they cast new light on the emergence of Christianity and of Rabbinic Judaism. (Wikipedia)
