Mythical Monarch Unmasked? Mysterious Doings of Debir King of Eglon

The name 'Debir king of Eglon' (Joshua 10.3) appears very odd, since Debir is a familiar city name and Eglon prominent as a king's personal name. Moreover, the LXX has the city name Adullam where MT has Eglon. Various explanations are reviewed. It seems likely that Debir was indeed the city name and that it was transformed into a personal name in the course of redactional processes.
