Learn more about Nebo from the Easton’s Bible Dictionary

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.
