Respect for the Elder
(לב) מִפְּנֵ֤י שֵׂיבָה֙ תָּק֔וּם וְהָדַרְתָּ֖ פְּנֵ֣י זָקֵ֑ן וְיָרֵ֥אתָ מֵּאֱלֹהֶ֖יךָ אֲנִ֥י יְהוָֽה׃ (פ)
(32) You shall rise before the aged and show deference to the old; you shall fear your God: I am the LORD.

Kiddushin 32 b (stand before your elders)

§ The Sages taught with regard to the verse: “Before the hoary head you shall stand and you shall revere the face of an elder, and you shall fear your God” (Leviticus 19:32): One might have thought that it is obligatory to stand before a simple [ashmai] elder. Therefore, the verse states: “elder,” and an “elder” means nothing other than a wise man, as it is stated: “Gather unto Me seventy men of the Elders of Israel, whom you know to be the Elders of the people” (Numbers 11:16). Rabbi Yosei HaGelili says: An “elder [zaken]” means nothing other than one who has acquired wisdom. He interprets the word zaken as a contraction of the phrase zeh kanna, meaning: This one has acquired. Elsewhere the word kanna is used in reference to wisdom, as it is stated that wisdom says: “The Lord acquired me [kanani] at the beginning of His way” (Proverbs 8:22). The baraita continues: One might have thought that one must stand before an elder as soon as he sees him, even from a distance. Therefore the verse states: “You shall stand and you shall revere” (Leviticus 19:32), which teaches: I said that one is obligated to stand only in a place where there is reverence. If he stands while the elder is still far away, it is not clear that he is doing so in his honor.

(א) משֶׁה קִבֵּל תּוֹרָה מִסִּינַי, וּמְסָרָהּ לִיהוֹשֻׁעַ, וִיהוֹשֻׁעַ לִזְקֵנִים, וּזְקֵנִים לִנְבִיאִים, וּנְבִיאִים מְסָרוּהָ לְאַנְשֵׁי כְנֶסֶת הַגְּדוֹלָה. הֵם אָמְרוּ שְׁלשָׁה דְבָרִים, הֱווּ מְתוּנִים בַּדִּין, וְהַעֲמִידוּ תַלְמִידִים הַרְבֵּה, וַעֲשׂוּ סְיָג לַתּוֹרָה:

(1) Moses received the torah at Sinai and transmitted it to Joshua, Joshua to the elders, and the elders to the prophets, and the prophets to the Men of the Great Assembly. They said three things: Be patient in [the administration of] justice, raise many disciples and make a fence round the Torah.

Pirket Avot 4:20

Elisha ben Abuyah said: He who learns when a child, to what is he compared? To ink written upon a new writing sheet. And he who learns when an old man, to what is he compared? To ink written on a rubbed writing sheet. Rabbi Yose ben Judah a man of Kfar Ha-babli said: He who learns from the young, to what is he compared? To one who eats unripe grapes, and drinks wine from his vat; And he who learns from the old, to what is he compared? To one who eats ripe grapes, and drinks old wine. Rabbi said: don’t look at the container but at that which is in it: there is a new container full of old wine, and an old [container] in which there is not even new [wine].

Berachot 8b

Rabbi Yehoshua ben Levi further advised: And be careful to continue to respect an elder who has forgotten his Torah knowledge due to circumstances beyond his control. Even though he is no longer a Torah scholar, he must still be respected for the Torah that he once possessed. As we say: Both the tablets of the Covenant and the broken tablets are placed in the Ark of the Covenant in the Temple. Even though the first tablets were broken, their sanctity obligates one not to treat them with contempt. An elder who forgot the Torah knowledge he once possessed is likened to these broken tablets.

(כא) הוּא הָיָה אוֹמֵר, בֶּן חָמֵשׁ שָׁנִים לַמִּקְרָא, בֶּן עֶשֶׂר לַמִּשְׁנָה, בֶּן שְׁלשׁ עֶשְׂרֵה לַמִּצְוֹת, בֶּן חֲמֵשׁ עֶשְׂרֵה לַתַּלְמוּד, בֶּן שְׁמֹנֶה עֶשְׂרֵה לַחֻפָּה, בֶּן עֶשְׂרִים לִרְדֹּף, בֶּן שְׁלשִׁים לַכֹּחַ, בֶּן אַרְבָּעִים לַבִּינָה, בֶּן חֲמִשִּׁים לָעֵצָה, בֶּן שִׁשִּׁים לַזִּקְנָה, בֶּן שִׁבְעִים לַשֵּׂיבָה, בֶּן שְׁמֹנִים לַגְּבוּרָה, בֶּן תִּשְׁעִים לָשׁוּחַ, בֶּן מֵאָה כְּאִלּוּ מֵת וְעָבַר וּבָטֵל מִן הָעוֹלָם:

(21) He used to say: At five years of age the study of Scripture; At ten the study of Mishnah; At thirteen subject to the commandments; At fifteen the study of Talmud; At eighteen the bridal canopy; At twenty for pursuit [of livelihood]; At thirty the peak of strength; At forty wisdom; At fifty able to give counsel; At sixty old age; At seventy fullness of years; At eighty the age of “strength”; At ninety a bent body; At one hundred, as good as dead and gone completely out of the world.

Bereishit Rabba 65

Rabbi Yehuda ben Shimon said: “Avraham asked for old age, pleading before God, ‘Sovereign of the Universe, when a man and his son enter a town, people don't know whom to honor, but if You crown the father with the appearance of old age, they will know whom to honor.’ The Holy One, Blessed be He, said to him: ‘You have asked well, and it shall begin with you.’ From the beginning of the book until here, old age is not mentioned, but when Avraham arises, the appearance of old age is granted to him: ‘And Avraham was old, well advanced in years’ (Bereishit 24:1).”

Berachot 27 b-28a (age as a sign of authority)

Rather, suggested the Sages, let us establish Rabbi Elazar ben Azarya in his place, his outstanding characteristics set him apart from the other candidates. He is wise, rich, and a tenth generation descendant of Ezra. The Gemara explains: He is wise, so if Rabban Gamliel raises a challenge in matters of Torah, he will answer it and not be embarrassed. And he is rich, so if the need arises to pay homage to the Caesar’s court and serve as a representative of Israel to lobby and negotiate, he has sufficient wealth to cover the costs of the long journeys, taxes, and gifts, so he too is able to go and pay homage. And he is a tenth generation descendant of Ezra, so he has the merit of his ancestors, and Rabban Gamliel will be unable to cause him to be punished. They came and said to him: Would the Master consent to being the Head of the Yeshiva? He said to them: I will go and consult with my household. He went and consulted with his wife. She said to him: There is room for concern. Perhaps they will remove you from office just as they removed Rabban Gamliel. He said to her, based on the folk saying: Let a person use an expensive goblet one day and let it break tomorrow. In other words, one should take advantage of an opportunity that presents itself and he need not concern himself whether or not it will last. She said to him: You have no white hair, and it is inappropriate for one so young to head the Sages. The Gemara relates: That day, he was eighteen years old, a miracle transpired for him and eighteen rows of hair turned white. The Gemara comments: That explains that which Rabbi Elazar ben Azarya said: I am as one who is seventy years old and he did not say: I am seventy years old, because he looked older than he actually was.

(ט) מִי שֶׁהוּא זָקֵן מֻפְלָג בְּזִקְנָה אַף עַל פִּי שֶׁאֵינוֹ חָכָם עוֹמְדִין לְפָנָיו. וַאֲפִלּוּ הֶחָכָם שֶׁהוּא יֶלֶד עוֹמֵד בִּפְנֵי הַזָּקֵן הַמֻּפְלָג בְּזִקְנָה. וְאֵינוֹ חַיָּב לַעֲמֹד מְלֹא קוֹמָתוֹ אֶלָּא כְּדֵי לְהַדְּרוֹ. וַאֲפִלּוּ זָקֵן כּוּתִי מְהַדְּרִין אוֹתוֹ בִּדְבָרִים וְנוֹתְנִין לוֹ יָד לְסָמְכוֹ שֶׁנֶּאֱמַר (ויקרא יט לב) "מִפְּנֵי שֵׂיבָה תָּקוּם" כָּל שֵׂיבָה בְּמַשְׁמָע:

(9) For one who is old and distinguished in age, though not a scholar, it is obligatory to rise up; even a young scholar should rise before an old man distinguished in age; but the obligation is not to rise before him in full height, only enough to honor him. It is proper to honor with words even the aged Kuthean and to give him a leaning hand, as it is said: "Thou shalt rise up before the hoary head", the inference being that it includes all hoary heads.8Ibid.
