Resen is one of Nimrod's cities (Genesis 10:12), “between Nineveh and Calah.”
It has been supposed that the 4 cities named in this verse were afterwards combined into 1, under the name of Nineveh.
Resen was on the east side of the Tigris. It is probably identified with the mound of ruins called Karamless.
