This chapter examines the role of fear in the Pentateuchal legal collections. Fear of foreigners is conspicuous in laws regulating relationships with other peoples. Fear of divine punishment is frequently employed as a deterrent in motivating obedience. Fear of demonic or supernatural powers is implicit in certain rituals, not least in some that effect purification or atonement. This is not a study of the semantics of fear, but of the emotional role that fear seems to play within and behind the texts that are discussed. I note how fear both counteracts and interacts with other emotions, particularly empathy and disgust. I also relate my analysis to recent discussions about the interrelationship, dating, and social contexts of various Pentateuchal legal collections.
