New Defender's Study Bible Notes
5:25 Lamech. “Lamech” probably means “conqueror.” It is interesting that Lamech and his grandfather Enoch both appear to have been named after their older relatives in the line of Cain, possibly as a gesture of family affection in hope of leading the Cainites back to God. It is also interesting that these are the only two antediluvian patriarchs in the Sethitic line who did not outlive their fathers. Furthermore, Enoch and Lamech are the only two of these patriarchs from whom have been handed down to us fragments of their prophecies (Jude 14,15; Genesis 5:29).
