Siman - Shabbos Daf 126
- What the Chochomim hold regarding window shutters
The Mishnah on 125b quotes Rebbi Eliezer who holds that one may close a window shutter on Shabbos, as long as the shutter is tied to the building, and is also hanging in the air. On this, the Chochomim stated, בין כך ובין כך פוקקין בו, - in either case we may shutter the window with it. The Gemara here brings a machlokes Amoraim regarding what the Chochomim were referring to.
- Rebbe Abba said in the name of Rav Kahana that the Chochomim permitted closing the shutter בין קשור בין אינו קשור – whether the shutter was tied to the building or not, והוא שמתוקן, provided that it was mentally prepared for use as a shutter prior to Shabbos.
- Rebbe Yirmiyah said that the Chochomim permitted closing the shutter בין תלוי ובין שאינו תלוי והוא שקשור - whether the shutter was suspended in the air or not, provided that it was tied to the building. Mental preparation is not sufficient.
- Cover handles
The final Mishnah in the perek states that vessel-covers that have handles, may be moved on Shabbos. Rebbe Yose disagrees and says that only כסוי קרקעות - covers of holes in the ground, need to have handles in order to be permitted, but כסוי כלים - vessel-covers, may be moved on Shabbos whether they have handles or not.
Rashi explains that it is necessary for the covers of holes in the ground, such as pits or cisterns, to have handles, so that it will be clear that the cover is not there permanently. Using a cover without a handle will look like he is sealing the hole permanently and will appear like boneh.
- Clearing away boxes of straw or produce
The opening Mishnah of the eighteenth perek states that one may clear away on Shabbos four or five boxes of straw or produce, מפני האורחים ומפני בטול בית מדרש, for guests, or to make room for talmidim to attend a shiur on Shabbos.
Rashi explains that this is permitted for the purposes of the mitzvah of hachnasas orchim and Talmud Torah, respectively, even though removing the boxes involves טירחא דשבת - exertion on Shabbos.
