Asshur

Concise Bible Dictionary:

In Genesis 10:1111Out of that land went forth Asshur, and builded Nineveh, and the city Rehoboth, and Calah, (Genesis 10:11) it would appear from the AV (KJV) that a son of Ham named Asshur built Nineveh; and then in Genesis 10:2222The children of Shem; Elam, and Asshur, and Arphaxad, and Lud, and Aram. (Genesis 10:22) and 1 Chronicles 1:17 Asshur is named as the son of Shem. But in the margin of Genesis 10:1111Out of that land went forth Asshur, and builded Nineveh, and the city Rehoboth, and Calah, (Genesis 10:11) it reads that “he went out into Assyria,” that is, Nimrod went forth into Asshur or Assyria (the Hebrew is the same). This is confirmed by Micah 5:66And they shall waste the land of Assyria with the sword, and the land of Nimrod in the entrances thereof: thus shall he deliver us from the Assyrian, when he cometh into our land, and when he treadeth within our borders. (Micah 5:6), where Assyria and Nimrod are associated together. Assyria is traced to Asshur or Assur, a son of Shem. Nimrod came afterward and may have subdued the country, but with what result is not shown.
