This book goes behind the Greek text of the Gospel of Mark and reconstructs some of its sources in the original Aramaic, the language that Jesus spoke. This work has been made possible by the publication of all the Aramaic Dead Sea Scrolls, which provide a basis of Jewish Aramaic for the right period. By reconstructing Aramaic sources and interpreting them in their original context, this book raises the level of proof that Jesus said and did some of the things attributed to him in our earliest sources.
