Genesis 10 gives us a great deal of information about Nimrod and his heritage.
Genesis 10:1 identifies the sons of Noah and their sons. “Now these are the generations of the sons of Noah, Shem, Ham, and Japheth: and unto them were sons born after the flood.” Immediately we understand where the post-flood population came from.
Second, there is a pattern to the description used in the genealogy of the three sons. The pattern establishes the lineage of sons from Noah, reveals the general geography of their migration, concludes with statement about the language they spoke, the land the inhabited the family they were part of (Genesis 10:5).
Third, we learn that Nimrod is unique. Besides being identified as ghib-bore (Hebrew for mighty, the same term to identify God) he is the first individual to establish a post flood kingdom and it remains (spiritually) to this day. Genesis 10:10 “And the beginning of his kingdom was Babel, and Erech, and Accad, and Calneh, in the land of Shinar.” He establishes four cities: Babel, Erech, Accad and Calneh all in the region of Shinar.
Fourth, Nimrod had influence of his cousin Asshur. Asshur is Shem’s son according to Genesis 10:22 “The children of Shem; Elam, and Asshur, and Arphaxad, and Lud, and Aram.” Asshur apparently migrated with Nimrod to the plain of Shinar and from there, “Out of that land went forth Asshur, and builded Nineveh, and the city Rehoboth, and Calah” Genesis 10:11. This is the same Nineveh that the prophet Jonah is called to “Arise, go to Nineveh, that great city, and cry against it; for their wickedness is come up before me.” in Jonah 1:2. Nineveh repented for a short period and then returned to its pagan ways (Isaiah 37:36-38).
Extending our look at scriptures beyond Genesis 10, we find that the city Babel and then the resultant kingdom were completely wicked. Isaiah 13:10 sums up the character of Babylon, “And Babylon, the glory of kingdoms, the beauty of the Chaldees’ excellency, shall be as when God overthrew Sodom and Gomorrah.”
Other prophets and the book of Revelation give more information about Babylon and the worldwide influence that it exerted at the time and how Babylonianism continues through today.
