23 And Lamech saith to his wives: -- `Adah and Zillah, hear my voice; Wives of Lamech, give ear [to] my saying: For a man I have slain for my wound, Even a young man for my hurt;
24 For sevenfold is required for Cain, And for Lamech seventy and sevenfold.'
25 And Adam again knoweth his wife, and she beareth a son, and calleth his name Seth, `for God hath appointed for me another seed instead of Abel:' for Cain had slain him.
26 And to Seth, to him also a son hath been born, and he calleth his name Enos; then a beginning was made of preaching in the name of Jehovah.
