Short biography

Book description for show notes

From Mesopotamian ritual texts and the restrained Hebrew Bible through the Book of Watchers, the Dead Sea Scrolls, the Gospels, and the Ethiopian Orthodox tradition of the debtera, JJ Johnson traces how a sparse biblical vocabulary grew into an elaborate demonology that never granted evil a throne of its own.
