Genesis Chapter 4 Verse 24If Cain shall be avenged sevenfold, truly Lamech seventy and sevenfold.

Behold, thou hast driven me out this day from the face of the earth; and from thy face shall I be hid; and I shall be a fugitive and a vagabond in the earth; and it shall come to pass, [that] every one that findeth me shall slay me.

And the LORD said unto him, Therefore whosoever slayeth Cain, vengeance shall be taken on him sevenfold. And the LORD set a mark upon Cain, lest any finding him should kill him.

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 Tubalcain, an instructer of every artificer in brass and iron: and the sister of Tubalcain [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.

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.

This [is] the book of the generations of Adam. In the day that God created man, in the likeness of God made he him;

Male and female created he them; and blessed them, and called their name Adam, in the day when they were created.

And Adam lived an hundred and thirty years, and begat [a son] in his own likeness, after his image; and called his name Seth:

And the days of Adam after he had begotten Seth were eight hundred years: and he begat sons and daughters:

And all the days that Adam lived were nine hundred and thirty years: and he died.

And Seth lived an hundred and five years, and begat Enos:

And Seth lived after he begat Enos eight hundred and seven years, and begat sons and daughters:

And all the days of Seth were nine hundred and twelve years: and he died.
