R. Akiva said: This was told to me by Rabbeinu Hakadosh (Rebbi): There was a man in Eretz Yisrael called "Merutah" ("torn"). Once he climbed a hill to collect wood, and he saw the snake, but the snake did not see him, when at once the hair of his head fell out and he had no hair until the day of his death — wherefore he was called Merutah."
