Genesis 4:25 DBY

²³  And Lemech said to his wives: Adah and Zillah, hear my voice, Ye wives of Lemech, listen to my speech. For I have slain a man for my wound, and a youth for my bruise.

²⁴  If Cain shall be avenged seven-fold; Lemech seventy and seven fold.

²⁵  And Adam knew his wife again, and she bore a son, and called his name Seth: ... For God has appointed me another seed instead of Abel, because Cain has slain him.

²⁶  And to Seth, to him also was born a son; and he called his name Enosh. Then people began to call on the name of Jehovah.
