Abba Zeno was journeying in Palestine, he grew tired and sat down near a cucumber field to eat. Presently, the thought came to him, “Take a cucumber and eat it; what harm is there in that?” But he answered this thought, saying, “Thieves go to hell. So test yourself here and see if you can stand hellfire.” He then stood in the sun for five days, and after he had burned himself raw, he said: “So you cannot endure hellfire after all? If you cannot take it,” he said to his thought, “then do not steal food.”
