“And Zillah, she also bare Tubalcain, an instructer of every artificer in brass and iron: and the sister of Tubalcain was Naamah.”
King James Version (KJV)
4:22 From Tubal - Cain, probably the Heathen Vulcan came. Why Naamah is particularly named, we know not: probably they did, who lived when Moses wrote.
