Ab'arim. (regions beyond). A mountain or range of highlands on the east of the Jordan, in the land of Moab, facing Jericho, and forming the eastern wall of the Jordan valley at that part. Its most elevated spot was "the Mount Nebo, 'head' of 'the' Pisgah," from which Moses viewed the Promised Land before his death. These mountains are mentioned in Numbers 27:12; Numbers 33:47-48; Deuteronomy 32:49.
