Genesis 4:19

4:19 Lamech took two wives for himself; the name of the first was Adah, and the name of the second was Zillah.

Genesis 4:22-23

4:22 Now Zillah also gave birth to Tubal-Cain, who heated metal and shaped ¹  all kinds of tools made of bronze and iron. The sister of Tubal-Cain was Naamah.

4:23 Lamech said to his wives,

“Adah and Zillah! Listen to me!

You wives of Lamech, hear my words!

I have killed a man for wounding me,

a young man ²  for hurting me.

[4:22]  ¹ tn The traditional rendering here, “who forged” (or “a forger of”) is now more commonly associated with counterfeit or fraud (e.g., “forged copies” or “forged checks”) than with the forging of metal. The phrase “heated metal and shaped [it]” has been used in the translation instead.

[4:23]  ¹ tn The Hebrew term יֶלֶד (yeled) probably refers to a youthful warrior here, not a child.
