King James Bible
"And Zillah, she also bare Tubalcain, an instructer of every artificer in brass and iron: and the sister of Tubalcain was Naamah."
Zillah, Lamech's second wife, gives birth to Tubalcain, continuing the genealogy of Cain's line. This detail emphasizes the polygamous family structure introduced with Lamech and traces technological advancement through specific lineages. Tubalcain is credited as the first metalworker who taught others to forge tools and weapons from bronze and iron. This marks a significant technological leap in human civilization, showing how Cain's descendants pioneered material culture despite their spiritual alienation. The mention of Naamah is notable as she is the only daughter named in Cain's genealogy. Her name means 'pleasant' or 'beautiful,' and her inclusion without further detail has sparked various traditions about her significance in ancient narratives.
