אמר רבה בר בר חנה א"ר יוחנן שני זקנים היו בצידן אחד עשה כב"ש ואחד עשה כדברי ב"ה זה נותן טעם לדבריו כנגד פרי החג וזה נותן טעם לדבריו דמעלין בקדש ואין מורידין
Rabba bar bar Ḥana said that Rabbi Yoḥanan said: There were two Elders in Sidon, and one of them acted in accordance with the opinion of Beit Shammai, and one of them acted in accordance with the opinion of Beit Hillel. Each provided a reason for his actions: One gave a reason for his actions: The number of lights corresponds to the bulls of the Festival. And one gave a reason for his actions: The number of lights is based on the principle: One elevates to a higher level in matters of sanctity and one does not downgrade.
מִצְוַת נֵר חֲנֻכָּה מִצְוָה חֲבִיבָה הִיא עַד מְאֹד וְצָרִיךְ אָדָם לְהִזָּהֵר בָּהּ כְּדֵי לְהוֹדִיעַ הַנֵּס וּלְהוֹסִיף בְּשֶׁבַח הָאֵל וְהוֹדָיָה לוֹ עַל הַנִּסִּים שֶׁעָשָׂה לָנוּ. אֲפִלּוּ אֵין לוֹ מַה יֹּאכַל אֶלָּא מִן הַצְּדָקָה שׁוֹאֵל אוֹ מוֹכֵר כְּסוּתוֹ וְלוֹקֵחַ שֶׁמֶן וְנֵרוֹת וּמַדְלִיק:
The precept of lighting the Hanukkah lamp is exceedingly precious, and one should carefully observe it in order to acclaim the miracle, ever praising and thanking God for the miracles which he has performed for us. Even if one has nothing to eat except what he gets from charity, he should borrow, or sell his garment, to buy oil and lamps and light them.
גמל שהיה טעון פשתן ועבר ברשות הרבים ונכנס פשתנו לתוך החנות ודלקו בנרו של חנוני והדליק את הבירה בעל גמל חייב הניח חנוני נרו מבחוץ החנוני חייב רבי יהודה אומר בנר חנוכה פטור:
In the case of a camel that was laden with flax and was passing through the public domain, and its flax extended into a store and the flax caught fire from a lamp in the store belonging to the storekeeper, and as a result of the burning flax the camel set fire to the building together with all its contents, the owner of the camel is liable. But if the storekeeper placed his lamp outside, thereby causing the flax on the camel to catch fire, and consequently the building was set on fire, the storekeeper is liable. Rabbi Yehuda says: In a case where the lamp placed outside was a Hanukkah lamp, the storekeeper is exempt, since it is a mitzva for a Hanukkah lamp to be placed outside.
The comprehensive discussion of the Hanukkah lights found in this chapter, which, in effect, included all the halakhot of Hanukkah, underscored the role of the Shabbat lights. The conclusion was that, in virtually every matter, there is a contrast between Hanukkah lights and Shabbat lights. The objective of the mitzva to kindle the Shabbat lights is to illuminate. The mitzva of kindling the Hanukkah lights has no such practical objective; the mitzva is the act of kindling itself. The Shabbat lights are kindled so that the entire family can derive benefit from them. It is prohibited to derive benefit from the Hanukkah candles at all. Consequently, the Shabbat lamp must be equipped with materials that burn clearly and consistently. There is no such requirement for the Hanukkah candles. Their sole purpose is to publicize the miracle of Hanukkah.
