And the beginning of his kingdom (Nimrod) was Babel, and Erech, and Accad, and Calneh, in the land of Shinar. Genesis 10:10"Erech is also “Uruk,” one hundred miles southeast of Babylon, the legendary home of Gilgamesh. Accad gave its name to the Akkadian empire, perhaps the same as the Sumerian empire. Calneh is unidentified." ICR
