R' Shimon says: One who considers the outcome [of a deed]. R' Elazar says: A good heart. He [Rabban Yochanan ben Zakkai] said to them: I prefer the words of R' Elazar ben Arach to your words, for your words are included in his words.  He said to them: Go out and discern what is the evil path from which a man should distance himself. R' Eliezer says: An evil eye. R' Yehoshua says: A bad friend. R' Yose says: A bad neighbor. R' Shimon says: One who borrows and does not repay; one who borrows from man is like one who borrows from the Omni-present, as it says: The wicked one borrows and does not pay, while the Righteous One is gracious and gives. R' Elazar says: A wicked heart. He said to them: I prefer the words of Elazar ben Arach to your words, for your words are included in his words.
