NIMROD
Verse 9:8-10, refer to Cush's son Nimrod. Nimrod's name means "to rebel" or "let us rebel". Nimrod, is called a "mighty hunter". This is in sharp contrast to the prophecy of Noah, that Ham's descendants would be servants to Shem and Japheth. Nimrod built and apparently ruled the first great city after the Floor, Babylon. Afterward he extended his rule into Assyria and built Nineveh, Rehoboth and Calah. Nimrod was the first world ruler.

(and Bush is the Last? The Alpha & Omega Nimrod?)
The Bible does not say that Nimrod was responsible for the Tower of Babel, but it seems logical that he was being the founder and ruler of the city. The Babylonians invented the first false religion which was a worship of the stars, astrology. Babylon is infamous in Scripture as being a wicked city openly rebelling and fighting against God. The people of these great cities were major enemies of Israel throughout history. Nimrod was not a servant as Noah had prophesied, but the opposite a "mighty hunter".(2) It seems Nimrod's goal in life was to disprove the prophecy of his grandfather and it is possible Ham's resentment of his father Noah was kindled in his grandson.
