Among the first seven scrolls discovered in the caves of Qumran at the Dead Sea is a scroll given the name "The Book of Giants". It is thought to have been based on the Book of Enoch, a pseudepigraphical Jewish work from the third century BCE. The Book of Giants, like the Book of Enoch, concerns itself with the Nephilim, which are the offspring of fallen angels, who are called the Watchers. Two main versions of the text exist. The Dead Sea version is written in Aramaic. Another version has been found written in middle Persian, adapted from the Aramaic to fit into the Manichean religion. Both versions will be examined. Following theories speculating that the Book of Giants was once part of the Book of Enoch, we will attempt to place the two texts back together to render the complete story of the Watchers and the Nephilim. We will discover the history and contributions of these ancient scrolls and look carefully at their content and meaning. Throughout the combined texts of the Book of Giants and the Book of Enoch we will examine all the biblical and apocryphal references and parallels within the text. The result is an in-depth and panoramic view of the Angels, the Watchers, and the Nephilim, and how one of the giants of the Nephilim race may have survived the flood intended to cleanse the Earth of their horror.
