Thematic Bible: Oldest son of cain

Cain knew his wife intimately, and she conceived and gave birth to Enoch. Then Cain became the builder of a city, and he named the city Enoch after his son. Irad was born to Enoch, Irad fathered Mehujael, Mehujael fathered Methushael, and Methushael fathered Lamech.
