Mishnà su Salmi 37:78

Rabban Yohanan ben Zakkai received [the oral tradition] from Hillel and Shammai.He used to say: if you have learned much Torah, do not claim credit for yourself, because for such a purpose were you created. Rabban Yohanan ben Zakkai had five disciples and they were these: Rabbi Eliezer ben Hyrcanus, Rabbi Joshua ben Hananiah, Rabbi Yose, the priest, Rabbi Shimon ben Nethaneel and Rabbi Eleazar ben Arach. He [Rabbi Johanan] used to list their outstanding virtues: Rabbi Eliezer ben Hyrcanus is a plastered cistern which loses not a drop; Rabbi Joshua ben Hananiah happy is the woman that gave birth to him; Rabbi Yose, the priest, is a pious man; Rabbi Simeon ben Nethaneel is one that fears sin, And Rabbi Eleazar ben Arach is like a spring that [ever] gathers force. He [Rabbi Yohanan] used to say: if all the sages of Israel were on one scale of the balance and Rabbi Eliezer ben Hyrcanus on the other scale, he would outweigh them all. Abba Shaul said in his name: if all the sages of Israel were on one scale of the balance, and Rabbi Eliezer ben Hyrcanus also with them, and Rabbi Eleazar ben Arach on the other scale, he would outweigh them all.

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.
