He [Rabban Yohanan] said unto them: go forth and observe which is the right way to which a man should cleave? Rabbi Eliezer said, a good eye; Rabbi Joshua said, a good companion; Rabbi Yose said, a good neighbor; Rabbi Shimon said, foresight. Rabbi Elazar said, a good heart. He [Rabban Yohanan] said to them: I prefer the words of Elazar ben Arach, for in his words your words are included. He [Rabban Yohanan] said unto them: go forth and observe which is the evil way which a man should shun? Rabbi Eliezer said, an evil eye; Rabbi Joshua said, an evil companion; Rabbi Yose said, an evil neighbor; Rabbi Shimon said, one who borrows and does not repay for he that borrows from man is as one who borrows from God, blessed be He, as it is said, “the wicked borrow and do not repay, but the righteous deal graciously and give” (Psalms 37:21). Rabbi Elazar said, an evil heart. He [Rabban Yohanan] said to them: I prefer the words of Elazar ben Arach, for in his words your words are included.
