Genesis 4:19
19 And Lamech took two wives. The name of the one was Adah, and the name of the other Zillah.
Genesis 4:23–24
23 Lamech said to his wives:
“Adah and Zillah, hear my voice;
you wives of Lamech, listen to what I say:
I have killed a man for wounding me,
a young man for striking me.
24 kIf Cain’s revenge is sevenfold,
then Lamech’s is seventy-sevenfold.”
