With regard to the opinion that one need not rekindle the Hanukkah light if it is extinguished, the Gemara asks: And is it true that if the Hanukkah light is extinguished one is not bound to attend to it? The Gemara raises a contradiction from that which was taught in a baraita: The mitzva of kindling the Hanukkah lights is from sunset until traffic in the marketplace ceases. Does that not mean that if the light is extinguished, he must rekindle it so that it will remain lit for the duration of that period? The Gemara answers: No, the baraita can be understood otherwise: That if one did not yet light at sunset, he may still light the Hanukkah lights until traffic ceases. Alternatively, one could say that this is referring to the matter of its measure. One must prepare a wick and oil sufficient to burn for the period lasting from sunset until traffic ceases. If he did so, even if the light is extinguished beforehand, he need not relight it. The expression until traffic in the marketplace ceases is mentioned here, and the Gemara asks: Until when exactly is this time? Rabba bar bar Ḥana said that Rabbi Yoḥanan said: Until the traffic of the people of Tadmor [tarmoda’ei] ceases. They sold kindling wood and remained in the marketplace later than everyone else. People who discovered at sunset that they had exhausted their wood supply could purchase wood from them.
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.
ת"ר נר חנוכה מצוה להניחה על פתח ביתו מבחוץ אם היה דר בעלייה מניחה בחלון הסמוכה לרה"ר ובשעת הסכנה מניחה על שלחנו ודיו אמר רבא צריך נר אחרת להשתמש לאורה ואי איכא מדורה לא צריך ואי אדם חשוב הוא אע"ג דאיכא מדורה צריך נר אחרת:
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.
