One way of seeking communication from the gods of the Canaanites was by ecstatic frenzy. Some scholars believe that Israel learned it from the Canaanites and made it a part of their service. They believe that Israel's former prophets were ecstatics. Evidence is sought in the Old Testament especially from three passages: Numbers 11:25-29, 1 Samuel 10:1-13, and 1 Samuel 19:18-24. This paper studies these passages to determine their contribution to the biblical picture of early prophecy.
