Nimrod was the prototype of the worldly leader that the masses look up to and follow and worship in the political, economic, and religious systems: The man of stature that usurps the role of Christ in the hearts of the people. His kingdom began with Babel which became Babylon.
“Cush begot Nimrod; he began to be a mighty one on the earth. He was a mighty hunter before the LORD; therefore it is said, “Like Nimrod the mighty hunter before the LORD.” And the beginning of his kingdom was Babel, Erech, Accad, and Calneh, in the land of Shinar. From that land he went to Assyria and built Nineveh, Rehoboth Ir, Calah, and Resen between Nineveh and Calah (that is the principal city).” Genesis 10:8-12
