Genesis 4:16-26 KJV
And Cain went out from the presence of the LORD, and dwelt in the land of Nod, on the east of Eden. And Cain knew his wife; and she conceived, and bare Enoch: and he builded a city, and called the name of the city, after the name of his son, Enoch. And unto Enoch was born Irad: and Irad begat Mehujael: and Mehujael begat Methusael: and Methusael begat Lamech.
And Lamech took unto him two wives: the name of the one was Adah, and the name of the other Zillah. And Adah bare Jabal: he was the father of such as dwell in tents, and of such as have cattle. And his brother's name was Jubal: he was the father of all such as handle the harp and organ. And Zillah, she also bare Tubal-cain, an instructer of every artificer in brass and iron: and the sister of Tubal-cain was Naamah. And Lamech said unto his wives,
Adah and Zillah, Hear my voice;
Ye wives of Lamech, hearken unto my speech:
For I have slain a man to my wounding,
And a young man to my hurt.
If Cain shall be avenged sevenfold,
Truly Lamech seventy and sevenfold.
And Adam knew his wife again; and she bare a son, and called his name Seth: For God, said she, hath appointed me another seed instead of Abel, whom Cain slew. And to Seth, to him also there was born a son; and he called his name Enos: then began men to call upon the name of the LORD.
