This project has the purpose of analyzing the relationship which exists between specific biblical texts and the Watchers tradition in Enochic Judaism. The Enochic tradition was born from reflections about the problem of evil, and attribute its origin to the rebellion of angelic beings against God. These angels corrupted themselves by teaching forbidden secrets to men, and by both taking women as their wives and having sexual relations with them. From these unnatural relations were born hybrid beings, the Nephilim, who in turn polluted the earth. By means of both the spirits of the Nephilim dead and fallen angels, we encounter the development of a theology of demonology. In order to reach the purpose of this project, we will reflect on the biblical arguments for the problem of evil, then we will investigate the enochic tradition, and, finally, we will specifically analyze the relation between some biblical texts and the Watchers tradition. By means of this analysis, we will be able to perceive that there is in fact a literary relationship between these biblical texts and the Watchers tradition, originating from Enochic Judaism.
