Genesis 4:23

²¹  And his brother's name was Jubal: he was the father of all such as handle the harp and organ.

²²  And Zillah, she also bare Tubalcain, an instructer of every artificer in brass and iron: and the sister of Tubalcain was Naamah.

²³  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.

²⁴  If Cain shall be avenged sevenfold, truly Lamech seventy and sevenfold.

²⁵  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.
