Kollel Iyun Hadaf, Jerusalem
(a) How does the Gemara prove that Rebbi Yehudah holds 'Ad ve'Ad bi'Chlal' from the last of five testimonials of Rebbi Yehudah ben Bava, who ruled like him and said that the Tamid shel Shachar could be brought 'be'Arba Sha'os'?2)
(a) What is the difernce between "Ke'chom ha'Yom" and "ve'Cham ha'Shemesh ve'Namas"?In any event,the latter quotation (which refers to the Mon, where the Torah writes "ba'Boker, ba'Boker"), speaks about a time which is not included in morning. How will we reconcile this ...
(b) ... with the Rabbanan, according to whom morning lasts until mid-day?3) Rav used to Daven the Shabbos Davening before nightfall, the Rabbanan did not.
(a) What is the Halachah regarding P'lag ha'Minchah. Is it considered nightfall or not?One Erev Shabbos evening, Rebbi Yirmiyah bar Aba Davened (shel Shabbos be'Erev Shabbos) behind Rav. When Rav finished the Amidah before Rebbi Yirmiyah bar Aba, he did not walk in front of his Talmid to get to his seat.
(b) Which three Halachos do we learn from here?
4) Besides the above-mentioned, there are four other other acts of disrespect towards one's Rebbi which cause the Shechinah to depart.
(a) What are they?Rav Yehudah quotes Rav as saying that Davening beside one's Rebbi or behind him is forbidden.
(b) Then how could Rebbi Yirmiyah bar Aba Daven behind Rav?5) On another occasion, Rebbi Davened the Shabbos Davening on Erev Shabbos, and still found time to go to the bath-house, and to give a Shiur before it turned night.
(a) How does the Gemara reconcile this with Rav's statement 'In, Badilna'! referred to above?
(c) If someone who Davens Kabalas Shabbos early erroneously, is obligated to Daven again, then why did Rebbi tell a certain community (after the clouds had dispersed) that they did not need to Daven again?6)
(a) Is someone who Davens before nightfall on Erev Shabbos permitted to make Kiddush before nightfall?7)
(a) Why does the Mishnah use the strange Lashon of 'Tefilas ha'Erev Ein Lah Keva'?8) Why would they not choose ...
(a) ... Rebbi Yehoshua... to replace Rabban Gamliel?
(c) Whom *did* they choose, and why was he a better choice to the previous two?9)
(a) What did Rebbi Elazar ben Azarya do before he accepted the position?
