Rosh Kollel: Rabbi Mordecai Kornfeld
12TH CYCLE SHABBOS 40 (4 Sivan) - Dedicated by Rabbi Kornfeld's father, Mr. David Kornfeld, in memory of the members of his family, Hashem Yikom Damam, who perished at the hands of the Nazi murderers in the Holocaust and whose Yahrzeit is observed today: his mother (Mirel bas Yakov Mordechai), brothers (Shraga Feivel, Aryeh Leib and Yisachar Dov, sons of Mordechai), grandfather (Reb Yakov Mordechai ben Reb David [Shpira]) and aunt (Charne bas Yakov Mordechai [wife of Reb Moshe Aryeh Cohen z'l]).
(a) We learnt earlier, that even water that has been heated on Erev Shabbos is only permitted for washing one's face, arms and legs. How does Rav extend this Halachah?
(b) How does he then explain the words in the Beraisa 'Aval Lo Kol Gufo'?
(c) Shmuel disagrees with Rav. What does he hold?
(d) Why must the Halachah be like Shmuel?
(a) Rabah presents another version of Rav's opinion. What is it?
(b) The Gemara asks all the same Kashyos on the second version as it asked on the first, but has no answer to them. Why not?
(c) Abaye expressed surprise at Rav Yosef, who queried whether Rabah ruled like Rav or not, 'mi'Mah Nafshach': to begin with, Rav has just been proved wrong. What would be the problem if he had not?
(d) How do we justify Rav Yosef's query - on both scores?
(a) What is a 'Merchatz she'Pak'ka Nekavav me'Erev Shabbos'?
(b) What is its Din regarding using it ...
1. ... on Motza'ei Shabbos?
2. ... on Yom-Tov, if it was stopped up on Erev Yom-Tov?
(c) Why, according to Elazar ben Azarya and Rebbi Akiva, was it necessary to cover the hot water with planks?
(a) Why did Chazal forbid bathing in hot water on Shabbos?
(b) What prompted them to add steam-baths to the prohibition?
(c) Why did they then initially add the hot springs of Teverya to the list of prohibitions, and why did they later withdraw it?
(a) How do we learn from the Beraisa that it is permitted to call someone a sinner, even when he only transgresses no more that an Isur de'Rabbanan?
(b) The Beraisa permits one to walk in the bath-houses of the cities? What is the Chidush, and why specifically 'of the cities'?
(c) What is the Din regarding someone who wishes to warm himself beside a fire and also to rinse with cold water?
(a) What may someone who has stomach-pains ...
1. ... place on his stomach on Shabbos?
2. ... not place on his stomach on Shabbos?
(b) Why is this forbidden even during the week?
(c) What does the Tana Kama of the Beraisa hold with regard to placing a flask of cold water beside a fire on Shabbos?
(a) Rebbi Yehudah forbids placing a jar of oil next to the fire, like the Tana Kama forbids a flask of water. Rabban Shimon ben Gamliel permits oil only in an unusual way. What does he mean by that?
(b) According to the first Lashon in the Tana Kama, only water is forbidden to reach the stage of 'Yad Soledes Bo', but not oil. Why should oil be any different than water?
(c) What does 'Yad Soledes Bo' mean, and how do we guage its Shiur?
(d) On what grounds does Rebbi Yehudah then forbid placing a jar of oil beside the fire?
(a) Rabban Shimon ben Gamliel is the most stringent of all with regard to oil. What does he say?
(a) According to the second Lashon in the Tana Kama too, he forbids a jar of oil to be cooked, just like a flask of water. What is his reasoning, and in which point does he then argue with Raban Shimon ben Gamliel?
(b) On one occasion, Rav Yitzchak bar Avdimi followed Rebbi into the bathhouse (to serve him). He wanted to pour a jar of oil into the pool of hot water. How could Rebbi take a bath on Shabbos?
(c) Which three things did Rav Yitzchak bar Avdimi learn from the fact that Rebbi instructed him to first take out some water and put it into a container, and to pour the oil into that, but not directly into the bath?
(d) What problem do we have with Rebbi having instructed Rav Yitzchak bar Avdimi what to do?
(a) Regarding the prohibition of speaking Divrei Torah in a bathhouse, does it make any difference in which language the Torah is spoken - or thought?
(b) Then on what grounds did Rebbi instruct Rav Yitzchak bar Avdimi?
(c) Why did Chazal forbid one to wash the floor on Shabbos?
(d) How do we reconcile Ravina, who deduces from Rebbi that someone who cooks in the hot springs of Teverya on Shabbos is Chayav, with Rav Chisda, who says he is Patur?
(a) Why did Chazal forbid on Shabbos swimming ...
1. ... in a river?
2. ... even in a pool that is situated in a public place?
(b) Standing in a pool in one's courtyard is always permitted. Paddling too, is permitted, provided one does not lift one's feet off the ground. Why did Chazal forbid swimming even in a pool in one's own Chatzer?
(c) We conclude that swimmming in a private pool is permitted, provided it has 'Gidudi'. What are Gidudi? Why did Chazal forbid swimming in a pool without 'Gidudi'?
(d) According to Rashi's second explanation, why did they permit swimming in a pool with 'Gidudi'?
