Meaning: the name of an important Mesopotamian god who gave his name to the city of Assyria. The name is derived from Anshar, an Akkadian sky god, whose name means "whole heaven" or "all sky" from Sumerian an (sky) and šar (all, totally). Ashur seems to be a combination of different gods, given many characteristics of the Babylonian god Marduk, likely because of the power struggle going on between Babylonia and Assyria at the time.
Ashur is also the name of Noah's grandson from his son Shem, who survived the Great Flood in the Bible. Some sources say that he founded the city of Ashur but it seems more likely it was named after the god Ashur.
