Recently Ada Yardeni, the foremost paleographer working in Israel today, made a startling claim: More than 50 Dead Sea Scroll manuscripts were copied by the same scribe.1 The 54 manuscripts came from six different caves: Qumran Caves 1, 2, 3, 4, 6 and 11. Even more surprising, Yardeni identified the same scribal hand in a manuscript of the Joshua Apocryphon found 30 miles south of Qumran at the famous desert fortress of Masada, the last holdout in the Jewish revolt against Rome.
“It seems likely that some manuscripts from Qumran were carried south by refugees fleeing the Roman destruction of Qumran in 68 C.E. [Masada is south of Qumran]. But that’s only a best guess.”
