The Hellenistic origins of Jewish ritual immersion

The present study explores the origins of Jewish ritual immersion – inquiring when immersion first appeared as a rite of purification and what the reasons may have been for this development specifically at this time. Textual and archaeological evidence suggest that immersion emerged at some point during – or perhaps slightly prior to – the first half of the first century BCE. It is suggested here that the practice grew out of contemporary bathing practices involving the Hellenistic hip bath. Through a process of ritualization, full-body immersion emerged as a method of purificatory washing clearly differentiated from profane bathing. By way of a subsequent process of ‘hyper-ritualization’, some ventured further to distinguish purificatory ablutions from profane bathing by restricting use of ‘drawn water’ for purification and by assigning impurity to anyone who bathed in such water. Before us is an enlightening example of one of the many ways wherein Jewish religious practices evolved and adapted in response to Hellenistic cultural innovations.
