I'm just throwing this out there for consideration or discussion. I think it fits.
Gen 4
18 And unto Enoch was born Irad: and Irad begat Mehujael: and Mehujael begat Methusael: and Methusael begat Lamech.
19 And Lamech took unto him two wives: the name of the one was Adah, and the name of the other Zillah.
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.
