The Sages taught in a baraita: The basic mitzva of Hanukkah is each day to have a light kindled by a person, the head of the household, for himself and his household. And the mehadrin, i.e., those who are meticulous in the performance of mitzvot, kindle a light for each and every one in the household. And the mehadrin min hamehadrin, who are even more meticulous, adjust the number of lights daily. Beit Shammai and Beit Hillel disagree as to the nature of that adjustment. Beit Shammai say: On the first day one kindles eight lights and, from there on, gradually decreases the number of lights until, on the last day of Hanukkah, he kindles one light. And Beit Hillel say: On the first day one kindles one light, and from there on, gradually increases the number of lights until, on the last day, he kindles eight lights. Ulla said: There were two amora’im in the West, Eretz Yisrael, who disagreed with regard to this dispute, Rabbi Yosei bar Avin and Rabbi Yosei bar Zevida. One said that the reason for Beit Shammai’s opinion is that the number of lights corresponds to the incoming days, i.e., the future. On the first day, eight days remain in Hanukkah, one kindles eight lights, and on the second day seven days remain, one kindles seven, etc. The reason for Beit Hillel’s opinion is that the number of lights corresponds to the outgoing days. Each day, the number of lights corresponds to the number of the days of Hanukkah that were already observed. And one said that the reason for Beit Shammai’s opinion is that the number of lights corresponds to the bulls of the festival of Sukkot: Thirteen were sacrificed on the first day and each succeeding day one fewer was sacrificed (Numbers 29:12–31). The reason for Beit Hillel’s opinion is that the number of lights is based on the principle: One elevates to a higher level in matters of sanctity and one does not downgrade. Therefore, if the objective is to have the number of lights correspond to the number of days, there is no alternative to increasing their number with the passing of each day. 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.
The Sages taught in a baraita: It is a mitzva to place the Hanukkah lamp at the entrance to one’s house on the outside, so that all can see it. If he lived upstairs, he places it at the window adjacent to the public domain. And in a time of danger, when the gentiles issued decrees to prohibit kindling lights, he places it on the table and that is sufficient to fulfill his obligation. Rava said: One must kindle another light in addition to the Hanukkah lights in order to use its light, as it is prohibited to use the light of the Hanukkah lights. And if there is a bonfire, he need not light an additional light, as he can use the light of the bonfire. However, if he is an important person, who is unaccustomed to using the light of a bonfire, even though there is a bonfire, he must kindle another light.
The Gemara asks: What is Hanukkah, and why are lights kindled on Hanukkah? The Gemara answers: The Sages taught in Megillat Ta’anit: On the twenty-fifth of Kislev, the days of Hanukkah are eight. One may not eulogize on them and one may not fast on them. What is the reason? When the Greeks entered the Sanctuary they defiled all the oils that were in the Sanctuary by touching them. And when the Hasmonean monarchy overcame them and emerged victorious over them, they searched and found only one cruse of oil that was placed with the seal of the High Priest, undisturbed by the Greeks. And there was sufficient oil there to light the candelabrum for only one day. A miracle occurred and they lit the candelabrum from it eight days. The next year the Sages instituted those days and made them holidays with recitation of hallel and special thanksgiving in prayer and blessings. We learned there in a mishna with regard to damages: In the case of a spark that emerges from under a hammer, and went out of the artisan’s workshop, and caused damage, the one who struck the hammer is liable. Similarly, in the case of a camel that is laden with flax and it passed through the public domain, and its flax entered into a store, and caught fire from the storekeeper’s lamp, and set fire to the building, the camel owner is liable. Since his flax entered into another’s domain, which he had no permission to enter, all the damages were caused due to his negligence. However, if the storekeeper placed his lamp outside the store and it set fire to the flax, the storekeeper is liable, as he placed the lamp outside his domain where he had no right to place it. Rabbi Yehuda says: If the flax was set on fire by the storekeeper’s Hanukkah lamp that he placed outside the entrance to his store, he is not liable, as in that case, it is permitted for the storekeeper to place his lamp outside. Ravina said in the name of Rabba: That is to say that it is a mitzva to place the Hanukkah lamp within ten handbreadths of the ground. As if it should enter your mind to say that he may place it above ten handbreadths, why is the storekeeper exempt? Let the camel owner say to the storekeeper: You should have placed the lamp above the height of a camel and its rider, and then no damage would have been caused. By failing to do so, the storekeeper caused the damage, and the camel owner should not be liable. The Gemara rejects this: And perhaps one is also permitted to place the Hanukkah lamp above ten handbreadths, and the reason Rabbi Yehuda exempted the storekeeper was due to concern for the observance of the mitzva of kindling Hanukkah lights. He held that if you burden one excessively, he will come to refrain from performing the mitzva of kindling Hanukkah lights. Since the storekeeper placed the Hanukkah lamp outside at the behest of the Sages, the storekeeper should not be required to take extra precautions. With regard to the essence of the matter Rav Kahana said that Rav Natan bar Manyumi taught in the name of Rabbi Tanḥum:
