Rabbi Elazar ben Arach

הוּא הָיָה אוֹמֵר, אִם יִהְיוּ כָל חַכְמֵי יִשְׂרָאֵל בְּכַף מֹאזְנַיִם, וֶאֱלִיעֶזֶר בֶּן הֻרְקְנוֹס בְּכַף שְׁנִיָּה, מַכְרִיעַ אֶת כֻּלָּם. אַבָּא שָׁאוּל אוֹמֵר מִשְּׁמוֹ, אִם יִהְיוּ כָל חַכְמֵי יִשְׂרָאֵל בְּכַף מֹאזְנַיִם וְרַבִּי אֱלִיעֶזֶר בֶּן הֻרְקְנוֹס אַף עִמָּהֶם, וְרַבִּי אֶלְעָזָר בֶּן עֲרָךְ בְּכַף שְׁנִיָּה, מַכְרִיעַ אֶת כֻּלָּם:

He [Rabban Yochanan ben Zakkai] used to say: If all the sages of Israel were on one side of a balance scale, and Rabbi Eliezer ben Horkenos were on the other side, he [Rabbi Eliezer] would outweigh them all. Abba Shaul said in the name of Rabban Yochanan ben Zakkai that if all the sages of Israel, including Rabbi Eliezer ben Horkenos, were on one side of a balance scale, and Rabbi Elazar ben Arakh were on the other side, he [Rabbi Elazar] would outweigh them all.

(ט) אָמַר לָהֶם, צְאוּ וּרְאוּ אֵיזוֹהִי דֶרֶךְ יְשָׁרָה שֶׁיִּדְבַּק בָּהּ הָאָדָם. רַבִּי אֱלִיעֶזֶר אוֹמֵר, עַיִן טוֹבָה. רַבִּי יְהוֹשֻׁעַ אוֹמֵר, חָבֵר טוֹב. רַבִּי יוֹסֵי אוֹמֵר, שָׁכֵן טוֹב. רַבִּי שִׁמְעוֹן אוֹמֵר, הָרוֹאֶה אֶת הַנּוֹלָד. רַבִּי אֶלְעָזָר אוֹמֵר, לֵב טוֹב. אָמַר לָהֶם, רוֹאֶה אֲנִי אֶת דִּבְרֵי אֶלְעָזָר בֶּן עֲרָךְ מִדִּבְרֵיכֶם, שֶׁבִּכְלַל דְּבָרָיו דִּבְרֵיכֶם.

(9) He (Yochanan ben Zakkai) said to them: Go out and see what is the straight path that a person should cling to. Rabbi Eliezer says: A good eye. Rabbi Yehoshua says: A good friend. Rabbi Yosi says: A good neighbor. Rabbi Shimon says: Seeing the consequences of one's actions. Rabbi Elazar says: A good heart. He said to them: I see the words of Rabbi Elazar ben Arakh [as better than] all of yours, because your words are included in his.

Ecclesiastes Rabbah

Rabbi Yochanan had five disciples, and as long as he lived they sat before him. When he died, they went to Yavneh. Rabbi Elazar ben Arach, however, joined his wife at Dyomset, a place of good water and beautiful scenery. He waited for them to come to him but they didn't. When they didn't come, he wanted to go to them, but his wife did not let him. "Who needs who" she asked. "They need me" he answered. She said to him: "In the case of a food container and mice, does the food go to the mice or do the mice go to the food?" He listened to her, and remained there until he forgot his learning. After a while they came and asked him "Which is better to eat along with a 'relish,' wheat bread or barley bread?" But he couldn't answer, because he had forgotten everything.
