• If we set aside the canon of scripture as it endured in Judaism, we see that Jubilees interprets the Book of the Watchers as scripture. Much as it does with Genesis, Leviticus, and Isaiah, Jubilees accounts for the Book of the Watchers, addresses problems in the apparent meaning, and provides a meaning consistent with a broader set of theological principles. Studying the manner in which Jubilees uses the Book of the Watchers leads us to a greater understanding of the concept of scripture held by at least one second-century teacher, the process of interpretation when the problems in the source are deeply theological, and the process of composition. Tracing the tensions in the sources used and produced by the author of Jubilees will lead us to a discussion of authorship that relies on rhetorical analysis rather than multiplicity of authorship to explain the use of the Book of the Watchers in Jubilees.
