Genesis 10:8-10
10:8 Cush was the father of Nimrod; he began to be a valiant warrior on the earth.
10:9 He was a mighty hunter before the Lord. (That is why it is said, “Like Nimrod, a mighty hunter before the Lord.”)
10:10 The primary regions of his kingdom were Babel, Erech, Akkad, and Calneh in the land of Shinar.
