Genesis 4:16-26 NASB
Then Cain went out from the presence of the LORD, and settled in the land of Nod, east of Eden.
Cain had relations with his wife and she conceived, and gave birth to Enoch; and he built a city, and called the name of the city 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. Lamech took to himself two wives: the name of the one was Adah, and the name of the other, Zillah. Adah gave birth to Jabal; he was the father of those who dwell in tents and have livestock. His brother’s name was Jubal; he was the father of all those who play the lyre and pipe. As for Zillah, she also gave birth to Tubal-cain, the forger of all implements of bronze and iron; and the sister of Tubal-cain was Naamah.
Lamech said to his wives,
“Adah and Zillah,
Listen to my voice,
You wives of Lamech,
Give heed to my speech,
For I have killed a man for wounding me;
And a boy for striking me;
If Cain is avenged sevenfold,
Then Lamech seventy-sevenfold.”
Adam had relations with his wife again; and she gave birth to a son, and named him Seth, for, she said, “God has appointed me another offspring in place of Abel, for Cain killed him.” To Seth, to him also a son was born; and he called his name Enosh. Then men began to call upon the name of the LORD.
