Biblical and post-Biblical texts refer to the tradition of the betrayal of Edom. During the
conquest the brother-nation of Edom would have betrayed Judah by choosing sides with the
Babylonians. Historical and archaeological evidence for this ‘fact’ is absent or not convincing.
It is argued that the occupation of Southern Judah by the Edomites in late Babylonian and/or
Persian times would have been the source of this claimed tradition.
