The Genesis story of Cain's murder of Abel is often told as a simplistic contrast between the innocence of Abel and the evil of Cain. This book subverts that reading of the Biblical text by utilising Giorgio Agamben's concepts of homo sacer, the state of exception and the idea of sovereignty to re-examine this well-known tale of fratricide and bring to the fore its political implications. Drawing from political theory, philosophy, and psychoanalysis, this book creates a theoretical framework from which to do two things: firstly, to describe and analyse the history of interpretation of Genesis 4:1-16, and secondly to propose an alternative reading of the Biblical text that incorporates other texts inside and outside of the Biblical canon. This intertextual analysis will highlight the motives of violence, law, divine rule, and the rejected as they emerge in different contexts and will evaluate them in an Agambenian framework. The unique approach of this book makes it vital reading for any academic with interests in Biblical Studies and Theology and their interactions with politics and ethics.
