Resen
     head of the stream; bridle, one of Nimrod's cities (Gen. 10:12),
     "between Nineveh and Calah." It has been supposed that the four
     cities named in this verse were afterwards combined into one
     under the name of Nineveh (q.v.). Resen was on the east side of
     the Tigris. It is probably identified with the mound of ruins
     called Karamless.
