Their usual phrase when speaking of him is "Asshur, my lord." They represent themselves as passing their lives in his service.

It is to spread his worship that they carry on their wars.

They fight, ravage, destroy in his name.
Finally, when they subdue a country, they are careful to "set up the emblems of Asshur," and teach the people his laws and his worship.
The tutelage of Asshur over Assyria is strongly marked by the identity of his name with that of the country, which in the original is complete.
It is also indicated by the curious fact that, unlike the other gods, Asshur had no notorious temple or shrine in any particular city of Assyria, a sign that his worship was spread equally throughout the whole land, and not to any extent localized.

As the national deity, he had given name to the original capital; but even at Asshur (_Kileh-Sherghat_) it may be doubted whether there was any building which was specially his.
Therefore it is a reasonable conjectures that all the shrines throughout Assyria were open to his worship, to whatever minor god they might happen to be dedicated.
In the inscriptions the Assyrians are constantly described as "the servants of Asshur," and their enemies as "the enemies of Asshur." The Assyrian religion is "the worship of Asshur." No similar phrases are used with respect to any of the other gods of the Pantheon.
We can scarcely doubt that originally the god Asshur was the great progenitor of the race, Asshur, the son of Shen, deified.

It was not long, however, before this notion was lost, and Asshur came to be viewed simply as a celestial being--the first and highest of all the divine agents who ruled over heaven and earth.
