Kollel Iyun Hadaf, Jerusalem 1) (a) On Motza'ei Shabbos, may one use a light that a non-Jew lit, after Shabbos, from the light of a Jew (or vice-versa) for Birchas ha'Ner?2) (a) May one recite Birchas ha'Ner over a light that one sees burning outside the town?Also included in the Beraisa is the case of someone who meets a child holding a lamp, in which case, one is obligated to ask him whether he is a Jew or not. Depending on his answer, one will be either permitted, or forbidden, to use his lamp. (d) Why does the Beraisa pick the case of a child? Why not a grown-up?3) One cannot recite the Berachah over a light that is less bright than that which emanates from a furnace. (a) Why not?4) Beis Hillel maintain that, when they bring a lamp into the Beis Hamedrash after nightfall on Motza'ei Shabbos, one person recites the Berachah on behalf of everybody. According to Beis Shamai, each person recites his own Berachah. (a) What are their respective reasons?5) (a) Why may one not use a lamp that was lit for a dead person, for Havdalah?6) One does not recite a Berachah over Besamim that was designated for a bathroom. (a) Why then, does recite one over spices in a spicery, which would appear to be there in order for the spicer to make profit, but not to smell?7) According to the Tana Kama, if someone who is walking outside the town, smells the aroma of Besamim, it will depend upon whether the majority of the town's inhabitants are Jews or non-Jews, as to whether he must recite a Berachah or not. Rebbi Yehudah maintains that even if the majority are Jews, he will still not recite a Berachah over them. (a) Why not?In Teverya, they used to spice their clothes every Friday afternoon, and in Tzipori, every Motza'ei Shabbos. (b) What is the Din regarding the Berachah, if one smelt the spices that were used for that purpose?
8) Rav Yehudah quoting Rav, interprets our Mishnah to mean, that even if one is far away, one recites Birchas ha'Ner, as long as the light is sufficiently bright for him to benefit from, if he were standing close. (a) Then what does the Beraisa mean when it writes that one may not recite a Berachah over a light which he saw, but from which he did not benefit?One may recite Birchas ha'Ner over 'Gechalim Lochshos', but not over 'Gechalim Omemos'. (c) What are these, and how does one gauge whether the coals are still in the category of 'Lochshos' or not?9) Rava disagrees with Rav Yehudah. (a) How does *he* interpret the words in our Mishnah 'Ad she'Ya'osu le'Oro'? What degree of light is required to be able to use the light?Rav Yehudah recited a Berachah over a light outside the house of Ada Dayla, and Rava recited a Berachah outside that of Gurya bar Chama. (b) What is the significance of those two statements? Did they both do the same thing?10) According to Beis Shamai, someone who forgot, and left the house before having Bensched, is obligated to return to where he ate in order to Bensch. According to Beis Hillel, he may Bensch wherever he now is. (a) Does this Machlokes apply even when he left his place deliberately?The Gemara thought that maybe it does. (b) Then why did the Tana write 'and he forgot'?Beis Hillel asked Beis Shamai whether someone who ate on the rooftop of his palace, forgot and descended is obligated to climb up to the roof to Bensch (he seems to have taken it for granted that even Beis Shamai will agree that he is not). (c) What was Beis Shamai's response to this question?There were two Talmidim, one who followed the opinion of Beis Shamai, and the other, of Beis Hillel. (d) What exactly did they do, and what happened to them?11) Rabba bar bar Chana's coach was about to leave, when he remembered that he had not yet Bensched. (a) What was his dilemma?12) Our Mishnah gives the time-limit for Bensching as 'Ad Kedei she'Yis'Acheil ha'Mazon', which Resh Lakish interprets to mean - as long as he is still thirsty on account of what he ate. (a) How do we reconcile this with the four Milin (72 minutes) that Rebbi Ami quotes him as saying?13) Our Mishnah obligates one to answer 'Amen', even though he heard only the end of the Berachah. (a) How can one be Yotze a Berachah that one hears from someone else without hearing the entire Berachah?Rav and Rav Huna both instructed their sons to try and obtain the Kos shel Berachah in order to Bensch. But that is not the opinion of Rebbi Yossi (the Tana). (b) What does Rebbi Yossi say?14) (a) Does one answer 'Amen' after the Berachah of a child who makes a Berachah?
