Genocide, a neologism coined during World War II and now enshrined in international law, reflects an ancestral phenomenon as old as human history, if not older. It is a secularized version of what our predecessors understood by holy war, just war, and jihad as divine sanctions of murder and mayhem. The twentieth century anachronistically has applied the term to the Armenian massacres of World War I, and the United Nations today struggles how not to apply its definition to similar actions such as the tragic events in Rwanda, Bosnia, and Sudan, let alone threats of mass terrorist murder by a bevy of religious killers. While our contemporary market is nearly saturated with books on the rebirth of jihad in its current terrorist manifestation, and a number of studies have examined the biblical antecedents of genocide, Louis Feldman offers a unique perspective on several ancient rereadings of a revered text that can be read as potentially genocidal.
