Parshat Vayelekh: What's the difference between a sage and a clod?

(ז) וַיִּקְרָ֨א מֹשֶׁ֜ה לִֽיהוֹשֻׁ֗עַ וַיֹּ֨אמֶר אֵלָ֜יו לְעֵינֵ֣י כָל־יִשְׂרָאֵ֘ל חֲזַ֣ק וֶאֱמָץ֒ כִּ֣י אַתָּ֗ה תָּבוֹא֙ אֶת־הָעָ֣ם הַזֶּ֔ה אֶל־הָאָ֕רֶץ אֲשֶׁ֨ר נִשְׁבַּ֧ע ה' לַאֲבֹתָ֖ם לָתֵ֣ת לָהֶ֑ם וְאַתָּ֖ה תַּנְחִילֶ֥נָּה אוֹתָֽם׃ (ח) וַֽה' ה֣וּא ׀ הַהֹלֵ֣ךְ לְפָנֶ֗יךָ ה֚וּא יִהְיֶ֣ה עִמָּ֔ךְ לֹ֥א יַרְפְּךָ֖ וְלֹ֣א יַֽעַזְבֶ֑ךָּ לֹ֥א תִירָ֖א וְלֹ֥א תֵחָֽת׃

(7) Then Moses called Joshua and said to him in the sight of all Israel: “Be strong and resolute, for it is you who shall go with this people into the land that the LORD swore to their fathers to give them, and it is you who shall apportion it to them. (8) And the LORD Himself will go before you. He will be with you; He will not fail you or forsake you. Fear not and be not dismayed!”

(ז) שִׁבְעָה דְבָרִים בַּגֹּלֶם וְשִׁבְעָה בֶחָכָם. חָכָם אֵינוֹ מְדַבֵּר בִּפְנֵי מִי שֶׁהוּא גָדוֹל מִמֶּנּוּ בְחָכְמָה וּבְמִנְיָן, וְאֵינוֹ נִכְנָס לְתוֹךְ דִּבְרֵי חֲבֵרוֹ, וְאֵינוֹ נִבְהָל לְהָשִׁיב, שׁוֹאֵל כָּעִנְיָן וּמֵשִׁיב כַּהֲלָכָה, וְאוֹמֵר עַל רִאשׁוֹן רִאשׁוֹן וְעַל אַחֲרוֹן אַחֲרוֹן, וְעַל מַה שֶּׁלֹּא שָׁמַע, אוֹמֵר לֹא שָׁמָעְתִּי, וּמוֹדֶה עַל הָאֱמֶת. וְחִלּוּפֵיהֶן בַּגֹּלֶם:

(7) Seven things are [found] in a golem and seven in a wise man. A wise man does not speak in front of someone who is greater than him in wisdom or in number; and he does not interrupt the words of his fellow; and is not impulsive in answering; and he asks to the point and answers as is proper; and he speaks to the first [point] first and the last [point] last; and about that which he has not heard [anything], says, "I have not heard [anything]"; and he concedes to the truth. And their opposites [are the case] with a golem.

אבות דרבי נתן נוסחא א פרק לז

ומודה על האמת זה משה שנאמר ויאמר ה' אלי הטיבו אשר דברו (דברים י"ח י"ז). וכן הקדוש ברוך הוא הודה על האמת שנאמר כן בנות צלפחד דוברות (במדבר כ"ז ז'):

Avot de Rabbi Natan 37

And he concedes to the truth: This is Moses, as it says, "[This is just what you asked of the Lord your God at Horeb, on the day of the Assembly, saying, 'Let me not hear the voice of the Lord my God any longer or see this wondrous fire any more, lest I die.'] Whereupon the Lord said to me, 'They have done well in speaking thus.'" (Deuteronomy 18:16-17). And also the Holy Blessed One conceded the truth as it says, "The plea of Zelophehad's daughters is just." (Numbers 27:7)
