14 And Seth lived, after he begat Enos, eight hundred and seven years, and begat many sons and daughters.
15 And the children of men were numerous upon all the face of the land. And in those days Satan had great dominion among men, and raged in their hearts; and from thenceforth came wars and bloodshed; and a man's hand was against his own brother, in administering death, because of secret works, seeking for power.*
