Seventy descendants of Noah's three sons, covering the entire known world of the ancient author. This is not a dry genealogy — it is a theological map. Every nation on earth is accounted for, named, placed, and connected back to the one family that survived the flood. No people are outside God's purview. One name breaks the pattern with a biographical note: Nimrod, the first empire-builder, founder of Babylon and Nineveh. The next chapter will explain what happened to unite and then scatter these nations.
