In the middle of an otherwise repetitive genealogy in Genesis 10, one man is especially singled out:
Cush was the father of Nimrod, who became a mighty warrior on the earth. He was a mighty hunter before the Lord; that is why it is said, "Like Nimrod, a mighty hunter before the Lord." The first centers of his kingdom were Babylon, Uruk, Akkad and Kalneh, in Shinar. From that land he went to Assyria, where he built Nineveh, Rehoboth Ir, Calah and Resen, which is between Nineveh and Calah—which is the great city. (Genesis 10:8-12 NIV)
The text makes rather a big deal about him - he's the founder of seemingly Bablyon and Assyria (at least Ninevah), both of which obviously play a major role later in Israel's history. Is there any other record of this "mighty warrior" who founded these cities?
