Many people today think of Satan as a little red demon with a pointy tail and a pitchfork-but this vision of the devil developed over many centuries and would be foreign to the writers of the Old Testament, where this figure makes his first appearances. The earliest texts that mention the Satan-it is always the Satan in the Old Testament-portray him as an agent of Yahweh, serving as an executioner of evildoers. But over the course of time, the Satan came to be regarded more as God’s enemy than God’s agent and was blamed for a host of problems.

Biblical scholar Ryan E. Stokes explains the development of the Satan tradition in the Hebrew scriptures and the writings of early Judaism, describing the interpretive and creative processes that transformed an agent of Yahweh into the archenemy of good. He explores how the idea of a heavenly Satan figure factored into the problem of evil and received the blame for all that is wrong in the world.
