What is "asaruludu"

In Sumerian and Akkadian mythology Asaruludu is one of the Anunnaku. His name is also spelled Asarludu, Asarluhi, and Namshub.

As Namshub (shining), he is considered a protective deity, "the shining god that illuminates our path". The Enuma Elish describes Asaruludu as "the light of the gods". Another version states he is "the wielder of the flaming sword" and "ensures the most perfect safety".
