Genesis

Cain planted corn and decided
that he owned the land he worked;
Abel taught sheep to believe
he was kind, and cut their throats.

Eve never did learn to shut the door
on salesmen with catalogs of apples,
a deal of seed, and a wriggling discourse;
and at night she told Adam
about how they would be rich.

Never mind who finally murdered whom:
at that point it was just a matter of time.
