A Man's Crime Against Another

Genesis 4:19-24

19  And Lamech took unto him two wives: the name of the one was Adah, and the name of the other Zillah. 
20  And Adah bare Jabal: he was the father of such as dwell in tents, and of such as have cattle. 
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.
