Concise Bible Dictionary:
One of the ancient cities in the land of Shinar built by Nimrod (Gen. 10:10; Amos 6:2). Some identify it with Ctesiphon beyond the Tigris; others with Niffer, about 60 miles E. S. E.; but on the maps it is usually placed at 32° 10' N, 45° 5' E, not coinciding with either of these.
