Genesis 4:22

And Zillah, she also bare Tubal-cain, an instructer of every artificer in brass and iron: and the sister of Tubal-cain was Naamah.

1. Lamech and his other wife, Zillah, had a son named Tubal-cain.
2. Tubal-cain apparently was an expert in working with brass and iron.
3. All those who worked with brass and iron learned their skills from Tubal-cain.
4. Lamech and his wife, Zillah, had a daughter named Naamah.
5. It appears somewhat common for female names to have ended with "ah".
