Poisonous Snakes

Someone who speaks Lashon Hara is compared to a snake.  The gemara in Ta’anis (8a) tells us, in the future all the animals will gather around the snake and ask him, “The lion pounces his prey to eat and sustains himself, the wolf tears his enemies and nourishes himself.  Why does the poisonous snake kill his enemy? 

We can ask the same question when we poison other people’s reputation with no gain to ourselves.

“Zachor Eis Asher Asa Hashem L’Miriam BaDerech B’Tzaischem MiMitzrayim”

The Ramban and other Rishonim count among the Mitzvos Aseh Min HaTorah the mitzva of remembering and saying with your mouth each day what Hashem did to Miriam when she spoke about her brother Moshe.  The Chofetz Chaim in Shaar Tvunah Perek 12 says that being Mikayem this mitzva can save you from the aveira of Lashon Hara.  More than just saying the pasuk, says the Chofetz Chaim, one must think about the incident in order for it to have its intended effect.
