Genesis 4:16

13 And Cain said, My punishment is greater than my strength.

14 You have sent me out this day from the face of the earth and from before your face; I will be a wanderer in flight over the earth, and whoever sees me will put me to death.

15 And the Lord said, Truly, if Cain is put to death, seven lives will be taken for his. And the Lord put a mark on Cain so that no one might put him to death.

16 And Cain went away from before the face of the Lord, and made his living-place in the land of Nod on the east of Eden.

17 And Cain had connection with his wife and she became with child and gave birth to Enoch: and he made a town, and gave the town the name of Enoch after his son.

18 And Enoch had a son Irad: and Irad became the father of Mehujael: and Mehujael became the father of Methushael: and Methushael became the father of Lamech.

19 And Lamech had two wives; the name of the one was Adah, and the name of the other Zillah.
