Cain in Wikipedia
In the Hebrew Bible, Cain and Abel (Hebrew: קין ,הבל, Qayin,
Hevel) are two sons of Adam and Eve. The Qur'an also
contains this story, with the names Qabil and Habil.
In the Greek New Testament, Cain is referred to as εκ του
πονηρου.  In at least one translation this is rendered
"from the evil one", while others have "of the evil
one." Some interpreters take this to mean that Cain was
literally the son of the serpent in the Garden of Eden. A
parallel idea can be found in Jewish tradition, that the
serpent (Hebrew nahash נחש) from the Garden of Eden was
father to firstborn Cain.
In all versions, Cain is a crop farmer and his younger
brother Abel is a shepherd. Cain is portrayed as sinful,
committing the first murder by killing his brother, after
God has rejected his offerings of produce but accepted
the animal sacrifices brought by Abel.
The oldest known copy of the Biblical narration is from the
1st century Dead Sea Scrolls. Cain and Abel also
appear in a number of other texts, and the story is the
subject of various interpretations. Abel, the first
murder victim, is sometimes seen as the first martyr;
while Cain, the first murderer, is sometimes seen as an
ancestor of evil....
