The Children of Adam and Eve

Lamech is a character in the Genealogies of Adam in the Book of Genesis. He is the sixth generation descendant of Cain (Genesis 4:18); his father was named Methusael and he was responsible for the "Song of the Sword." He is also noted as thefirst polygamist mentioned in the Bible:

Then Lamech took for himself two wives: the name of one was Adah, and the name of the second was Zillah. And Adah bore Jabal. He was the father of those who dwell in tents and have livestock. His Brother’s name was Jubal. He was the father ofall those who play the harp and flute. And as for Zillah, she also bore Tubal-Cain, an instructor of every craftsman in Bronze and iron. And the sister of Tubal-Cain was Naamah.

Then Lamech said to his wives:

“Adah and Zillah, hear my voice;
Wives of Lamech, listen to my speech!
For I have killed a man for wounding me,
Even a Young man for hurting me.
If Cain shall be avenged sevenfold,
Then Lamech seventy-sevenfold.”

Genesis 4:19-24
