Genesis 4:16 Light Vs. Darkness (Two family lines)

The conflict between the seed of the serpent and the seed of the woman continues in this section with the development of two family lines – one godly and one ungodly. "Cain's family tree ends with the family of Lamech, an arrogant murderer whose 3 sons manufactured things for this world. Seth's line ends with Noah ("rest") whose sons gave the world a new beginning after the flood." (Wiersbe) Tragically, by the time Noah, his sons and their wives stepped on the ark, the two lines were indistinguishable. The only godly remnant that would remain would be Noah and his family.
