University of Iowa Assistant Professor Bob Cargill was featured on Bible Odyssey, a website dedicated to scholarly discussion of people, places, and passages of the Bible. In the video, he talked about the origins of baptism in Judaism.

Cargill has a joint appointment in the Departments of Classics and Religious Studies, both in the UI College of Liberal Arts & Sciences. He teaches courses on archaeology, biblical studies, and the digital humanities, among other subjects. He has appeared as an expert on numerous television documentaries and specials, and hosted a National Geographic Channel documentary.

In the Bible Odyssey video, Cargill discussed how the Christian approach to baptism was likely developed from a ritual immersion practice in Judaism. Prior to the advent of Christianity, Cargill said, Jews practiced ritual immersion to purify themselves for worship.
