<P> In the biblical Book of Genesis, Cain and Abel are the first two sons of Adam and Eve . Cain, the firstborn, was a farmer, and his brother Abel was a shepherd . The brothers made sacrifices to God, each of his own produce, but God favored Abel's sacrifice instead of Cain's . Cain then murdered Abel, whereupon God punished Cain to a life of wandering . Cain then dwelt in the land of Nod (נוֹד ‬, "wandering"), where he built a city and fathered the line of descendants beginning with Enoch . </P> <P> The narrative never explicitly states Cain's motive for murdering his brother, nor God's reason for rejecting Cain's sacrifice, nor details on the identity of Cain's wife . Some traditional interpretations consider Cain to be the originator of evil, violence, or greed . According to Genesis, Cain was the first human born and Abel was the first to die . </P>
