1)

(a) Rav Chananya bar Shalmaya and the disciples of Rav asked Rav Hamnuna the elder to go and see whether it was already dark, in which case they would have to stop eating and fix Shabbos.
What did they mean by that?

(b) What did Rav Hamnuna in the name of Rav answer them ?

(c) What did Rav mean when he said 'Ke'sheim she'Kova'as le'Ma'aser?

(a) What is the equivalent Din regarding *Havdalah* on Motza'ei Shabbos, and why is the Halachah different there?

(b) Does this mean that one may begin a meal on Motza'ei Shabbos before having recited Havdalah?

(a) If one began drinking wine (not during Shalosh Se'udos), may one continue to do so when the time for Havdalah arrives?

(b) Rav Amram quoting Rav, permitted water even Lechatchilah without reciting Havdalah.
What did Rav Huna say about that?

(c) How does Rav Amram explain Rebbi Akiva, who seems to corroborate Rav Huna's opinion? (see Tosfos)

(d) The Rabbanan of Rav Ashi's Beis Hamedrash were not fussy about drinking water before Havdalah.
Why were they more stringent by Kidush in this matter that by Havdalah?

(a) They asked Rav Nachman bar Yitzchak whether someone who failed to recite Kidush on Friday night should recite it during the day.
What did he reply?

(b) They then queried his reply from a Beraisa, which differentiates between Friday (and Yom-Tov) night and Shabbos (and Yom-Tov) day-time - with regards to reciting Kidush.
What does the Beraisa say and what did they ask him?

(c) How does the Gemara answer the Kashya?

(d) What does the Tana say about mentioning Shabbos in Birchas ha'Mazon? Does it make a distinction between Friday night and Shabbos day-time?

(a) If one has wine for Kidush, but limited funds for one's other Shabbos needs, which takes precedence, the Friday night meal or that of Shabbos lunch?

(b) In that case, why does the Beraisa rule that if one has only one cup of wine, he should use it for Kidush on Friday night? Would it not have been better to have left it for the day, so as to recite Kidush and honor the Shabbos meal with one stroke?

6)

(a) If the principle of 'Chavivah Mitzvah be'Sha'atah' applies even to Berachos, then why on Motza'ei Shabbos, does the Tana of the Beraisa say that someone who has only one cup of wine, should postpone Havdalah until after he has eaten, rather than recite Havdalah straight away?

(b) What did Rav Nachman bar Yitzchak mean when he said 'Lo Chakima Ana ve'Lo Gamarna Ana, Ela Sadarna Ana'?

(a) Is it necessary for someone who already said Havdalah in Tefilah to repeat it over a cup of wine?

(b) This is one of the eight things that we learn from the above Beraisa (in 6a.). How do we also learn from the Beraisa that ...

1. ... Birchas ha'Mazon must be recited over a cup of wine?
2. ... the Kos shel Berachah requires a Revi'is of wine?

(c) We also learn from the Beraisa that the person who recites the Birchas ha'Mazon should drink the wine.
Will the participants be Yotze ...

1. ... if somebody else drinks it?
2. ... if nobody drinks it?
3. ... if a child drinks it?

(d) What is the meaning of ...

1. ... 'Ta'amo Pegamo'?
2. ... 'Ta'am Mavdil'?

(a) We also learn from the Beraisa that one cup of wine may be used for two Berachos.
How do we reconcile this with what we learned earlier (on 102b) that this is not permitted because of 'Ein Osin Mitzvos Chavilos Chavilos'?

(b) The eighth point is that the author of the Beraisa must be Beis Shamai, according to the opinion of Rebbi Yehudah, who puts Ner before Besamim. Why can the author not be Rebbi Meir, who learns like that - even in Beis Hillel?

(c) What does Rava say about the two reasons 'Ta'amo Pegamo' and 'Kos shel Berachah Te'unah Shiur'?
