Easton's 1897 Bible Dictionary:

Nebo
   proclaimer; prophet. (1.) A Chaldean god whose worship was
   introduced into Assyria by Pul (Isa. 46:1; Jer. 48:1). To this
   idol was dedicated the great temple whose ruins are still seen
   at Birs Nimrud. A statue of Nebo found at Calah, where it was
   set up by Pul, king of Assyria, is now in the British Museum.

     (2.) A mountain in the land of Moab from which Moses looked
   for the first and the last time on the Promised Land (Deut.
   32:49; 34:1). It has been identified with Jebel Nebah, on the
   eastern shore of the Dead Sea, near its northern end, and about
   5 miles south-west of Heshbon. It was the summit of the ridge of
   Pisgah (q.v.), which was a part of the range of the "mountains
   of Abarim." It is about 2,643 feet in height, but from its
   position it commands a view of Western Palestine. Close below it
   are the plains of Moab, where Balaam, and afterwards Moses, saw
   the tents of Israel spread along.

     (3.) A town on the east of Jordan which was taken possession
   of and rebuilt by the tribe of Reuben (Num. 32:3,38; 1 Chr.
   5:8). It was about 8 miles south of Heshbon.

     (4.) The "children of Nebo" (Ezra 2:29; Neh. 7:33) were of
   those who returned from Babylon. It was a town in Benjamin,
   probably the modern Beit Nubah, about 7 miles north-west of
   Hebron.
