Genesis 5:32

One of the most important facts recorded in Genesis 10 is the foundation of the earliest monarchy in Babylonia by Nimrod the grandson of Ham (6,8,10). The primitive Babylonian empire was thus Hamitic, and of a cognate race with the primitive inhabitants of Arabia and of Ethiopia. (See ACCAD .)

The race of Ham were the most energetic of all the descendants of Noah in the early times of the post-diluvian world.
