Evil in the Rabbinic Tradition
“Rabbinic tradition … is remarkably ignorant of the existence of independent powers of evil … Satan in his various manifestations … is a power within the divine court and God’s system of justice … The first indication of a satanic rebellion against God in rabbinic literature is found in the eighth-century midrash Pirkey de-Rabbi Eliezer, but this seemed to have little impact until the twelfth century. The section of this midrash in which the rebellion is described was included in the Book Bahir, serving as its concluding chapter.”
