What is a Gadol?
With gratitude to מו״ר Rav Elya Chaim Swerdloff for teaching me these sources

מַעֲשֶׂה בְּרַבִּי אֱלִיעֶזֶר וְרַבִּי יְהוֹשֻׁעַ וְרַבִּי צָדוֹק שֶׁהָיוּ מְסוּבִּין בְּבֵית הַמִּשְׁתֶּה בְּנוֹ שֶׁל רַבָּן גַּמְלִיאֵל וְהָיָה רַבָּן גַּמְלִיאֵל עוֹמֵד וּמַשְׁקֶה עֲלֵיהֶם נָתַן הַכּוֹס לְרַבִּי אֱלִיעֶזֶר וְלֹא נְטָלוֹ נְתָנוֹ לְרַבִּי יְהוֹשֻׁעַ וְקִיבְּלוֹ אָמַר לוֹ רַבִּי אֱלִיעֶזֶר מָה זֶה יְהוֹשֻׁעַ אָנוּ יוֹשְׁבִין וְרַבָּן גַּמְלִיאֵל בְּרִיבִּי עוֹמֵד וּמַשְׁקֶה עָלֵינוּ אֲמַר לֵיהּ מָצִינוּ גָּדוֹל מִמֶּנּוּ שֶׁשִּׁמֵּשׁ אַבְרָהָם גָּדוֹל מִמֶּנּוּ וְשִׁמֵּשׁ אַבְרָהָם גְּדוֹל הַדּוֹר הָיָה וְכָתוּב בּוֹ וְהוּא עָמַד עֲלֵיהֶם וְשֶׁמָּא תֹּאמְרוּ כְּמַלְאֲכֵי הַשָּׁרֵת נִדְמוּ לוֹ לֹא נִדְמוּ לוֹ אֶלָּא לְעַרְבִיִּים וְאָנוּ לֹא יְהֵא רַבָּן גַּמְלִיאֵל בְּרִיבִּי עוֹמֵד וּמַשְׁקֶה עָלֵינוּ אָמַר לָהֶם רַבִּי צָדוֹק עַד מָתַי אַתֶּם מַנִּיחִים כְּבוֹדוֹ שֶׁל מָקוֹם וְאַתֶּם עוֹסְקִים בִּכְבוֹד הַבְּרִיּוֹת הַקָּדוֹשׁ בָּרוּךְ הוּא מֵשִׁיב רוּחוֹת וּמַעֲלֶה נְשִׂיאִים וּמוֹרִיד מָטָר וּמַצְמִיחַ אֲדָמָה וְעוֹרֵךְ שׁוּלְחָן לִפְנֵי כׇּל אֶחָד וְאֶחָד וְאָנוּ לֹא יְהֵא רַבָּן גַּמְלִיאֵל בְּרִיבִּי עוֹמֵד וּמַשְׁקֶה עָלֵינוּ

There was an incident involving Rabbi Eliezer and Rabbi Yehoshua and Rabbi Tzadok, who were reclining at the wedding of Rabban Gamliel’s son. And Rabban Gamliel, who was Nasi of the Sanhedrin at the time, was standing over them and serving them drinks. He gave the cup to Rabbi Eliezer and he would not accept it; he gave it to Rabbi Yehoshua and he accepted it. Rabbi Eliezer said to him: What is this, Yehoshua? We sit and the esteemed Rabban Gamliel stands over us and serves us drinks? Rabbi Yehoshua said to him: We found one greater than him who served his guests, as our forefather Abraham was greater than him and he served his guests. Abraham was the greatest man of his generation and it is written about him: “And he stood over them under the tree, and they ate” (Genesis 18:8). And lest you say: His guests appeared to him as ministering angels, and that is why he honored them, in fact they appeared to him only as Arabs. And if so, should not the esteemed Rabban Gamliel stand over us and serve us drinks? Rabbi Tzadok said to them: For how long will you ignore the honor due to the Omnipresent, and deal with the honor of people? You could cite a proof from God Himself. After all, the Holy One, Blessed be He, makes the winds blow, and raises the clouds, and brings the rain, and causes the earth to sprout, and sets a table before each and every creature. And should not the esteemed Rabban Gamliel stand over us and serve us drinks? This discussion indicates that even a Nasi may forgo the honor due him.

אָמַר רַבִּי יוֹחָנָן: כׇּל מָקוֹם שֶׁאַתָּה מוֹצֵא גְּבוּרָתוֹ שֶׁל הַקָּדוֹשׁ בָּרוּךְ הוּא, אַתָּה מוֹצֵא עִנְוְותָנוּתוֹ. דָּבָר זֶה כָּתוּב בַּתּוֹרָה, וְשָׁנוּי בַּנְּבִיאִים, וּמְשׁוּלָּשׁ בַּכְּתוּבִים. כָּתוּב בַּתּוֹרָה: ״כִּי ה׳ אֱלֹהֵיכֶם הוּא אֱלֹהֵי הָאֱלֹהִים וַאֲדוֹנֵי הָאֲדוֹנִים״, וּכְתִיב בָּתְרֵיהּ: ״עוֹשֶׂה מִשְׁפַּט יָתוֹם וְאַלְמָנָה״. שָׁנוּי בַּנְּבִיאִים: ״כֹה אָמַר רָם וְנִשָּׂא שׁוֹכֵן עַד וְקָדוֹשׁ וְגוֹ׳״, וּכְתִיב בָּתְרֵיהּ: ״וְאֶת דַּכָּא וּשְׁפַל רוּחַ״, מְשׁוּלָּשׁ בַּכְּתוּבִים, דִּכְתִיב: ״סוֹלּוּ לָרוֹכֵב בָּעֲרָבוֹת בְּיָהּ שְׁמוֹ״, וּכְתִיב בָּתְרֵיהּ: ״אֲבִי יְתוֹמִים וְדַיַּין אַלְמָנוֹת״.
Having mentioned the haftara read on Yom Kippur, the Gemara cites that which Rabbi Yoḥanan said: Wherever you find a reference in the Bible to the might of the Holy One, Blessed be He, you also find a reference to His humility adjacent to it. Evidence of this fact is written in the Torah, repeated in the Prophets, and stated a third time in the Writings. It is written in the Torah: “For the Lord your God is the God of gods and the Lord of lords” (Deuteronomy 10:17), and it is written immediately afterward: “He executes the judgment of the fatherless and widow” (Deuteronomy 10:18), displaying his humility in caring for even the weakest parts of society. It is repeated in the Prophets: “For thus says the High and Lofty One that inhabits eternity, Whose name is sacred” (Isaiah 57:15), and it is written immediately afterward: “In the high and holy place I dwell with him that is of a contrite and humble spirit, to revive the spirit of the humble, and to revive the heart of the contrite ones” (Isaiah 57:15). It is stated a third time in the Writings, as it is written: “Extol Him Who rides upon the clouds, Whose name is the Lord” (Psalms 68:5), and it is written immediately afterward: “A father of the fatherless, and a judge of widows” (Psalms 68:6).
