Lamech lived after he fathered Noah 595 years and had other sons and daughters.
and called his name Noah, saying, “Out of the ground that the Lord has cursed, this one shall bring us relief from our work and from the painful toil of our hands.”
Thus all the days of Lamech were 777 years, and he died.
The days of Adam after he fathered Seth were 800 years; and he had other sons and daughters.
