Genesis 4:16-19

16Cain went away from the Lord. He went to live in the land called Nod, which is east of Eden.

17Cain had sex with his wife. She became pregnant and she gave birth to Enoch. Cain started to build a city. He called the city Enoch because that was his son's name.

18Enoch became the father of Irad. Irad became the father of Mehujael. Mehujael became the father of Methushael. Methushael became the father of Lamech.

19Lamech married two women. One was called Adah. The other was called Zillah.
