Genesis 4:16-24

So Cain went away from the [manifested] presence of the LORD, and lived in the land of Nod [wandering in exile], east of Eden. Cain knew his wife [one of Adam’s descendants] and she conceived and gave birth to Enoch; and Cain built a city and named it Enoch, after the name of his son. Now to Enoch was born Irad, and Irad became the father of Mehujael, and Mehujael became the father of Methushael, and Methushael became the father of Lamech. And Lamech took for himself two wives; the name of the one was Adah, and the name of the other, Zillah. Adah gave birth to Jabal; he became the father of those [nomadic herdsmen] who live in tents and have cattle and raise livestock. His brother’s name was Jubal; he became the father of all those [musicians] who play the lyre and flute. Zillah gave birth to Tubal-cain, the smith (craftsman) and teacher of every artisan in instruments of bronze and iron. The sister of Tubal-cain was Naamah. Lamech said to his wives, “Adah and Zillah, Hear my voice; You wives of Lamech, Listen to what I say; For I have killed a man [merely] for wounding me, And a boy [only] for striking (bruising) me. “If Cain is avenged sevenfold [as the LORD said he would be], Then Lamech [will be avenged] seventy-sevenfold.”
