Genesis 5:9-13

Now Enosh lived ninety years, and fathered Kenan.

Then Enosh lived 815 years after he fathered Kenan, and he fathered other sons and daughters.

So all the days of Enosh were 905 years, and he died.

Now Kenan lived seventy years, and fathered Mahalalel.

Then Kenan lived 840 years after he fathered Mahalalel, and he fathered other sons and daughters.
