4:17    Cain and his wife had a son and named him Enoch. Then Cain built a city and named it after his son.

4:18    Enoch had a son named Irad, who was the father of Mehujael, and Mehujael had a son named Methushael, who was the father of Lamech.

4:19    Lamech had two wives, Adah and Zillah.

4:20    Adah gave birth to Jabal, who was the ancestor of those who raise livestock and live in tents.

4:21    His brother was Jubal, the ancestor of all musicians who play the harp and the flute.

4:22    Zillah gave birth to Tubal Cain, who made all kinds of tools out of bronze and iron. The sister of Tubal Cain was Naamah.

4:23    Lamech said to his wives,

          “Adah and Zillah, listen to me:

           I have killed a young man

                  because he struck me.

4:24    if seven lives are taken to pay for killing Cain,

         Seventy-seven will be taken if anyone kills me.”
