Bezer was a Biblical city in the desert plateau east of the Jordan that was designated a 'city of refuge' for the Reubenites by Moses, to which a person guilty of manslaughter could flee to avoid being killed in vengeance. The city is mentioned in Deuteronomy 4:43, Joshua 20:8, Joshua 21:36, 1Chronicles 6:78 and 1Chronicles 7:37.
