Lamech
Genesis 4:18
4:18 Lamech. The possible meaning of these names are: Irad, meaning “Townsman,” Mehujael, meaning “God gives life;” Methusael, meaning “Man of God;” Lamech, meaning “Conqueror.” The similarity of some of the names to those in the Sethitic line, as well as their religious “-el” endings, probably indicates that the two families kept in touch with each other and that the Cainitic line continued to believe in God as long as Adam remained alive to exercise some degree of patriarchal leadership.
