Asshur was the second son of Shem and the name associated with Assyria. The name also refers to the ancient Assyrian capital and is sometimes retained instead of being translated “Assyria.”
Asshur appears in genealogical passages as a son of Shem and in geographical passages as the name of the land or people associated with Assyria.
The original capital of Assyria was Asshur, represented by the mounds of Kalah Sherghat on the west bank of the Tigris. At a later time the capital was transferred to Nineveh.
