1. One may not hang a wine strainer on a peg on Shabbos or Yom Tov in the way he does so on a weekday.
2. Rav Kahana: If a person strains wine sediments on Shabbos in a strainer, the Chachamim say that he must bring a Chatas.
3. There is a dispute about what exactly one transgresses by straining wine sediments in a strainer.
4. Rav: One is permitted to open and close curtains on Shabbos.
5. There is a dispute about whether the Torah will ever be forgotten.


1. Even though hanging the strainer itself is clearly not prohibited according to Torah law, the Rabanan prohibited it because it is something that is normally done to perform work on weekdays and is akin to building a tent.
2. Rav Sheshes questions how the Chachamim could maintain that this act is a Torah prohibition when their disputant, Rebbi Eliezer (137b) says that it is entirely permitted. Nevertheless, Rav Kahana insists that this indeed is their argument.
3. Rabah: This is an act of Borer (separating). Rebbi Zeira: This is an act of Meraked (sifting).
4. This is not considered an Ohel, as there is no roof.
5. Rav and the Rabanan in Kerem b'Yavneh: Torah will one day be forgotten. Rebbi Shimon bar Yochai: Heaven forbid that this will ever happen. Rather, the verses that imply that the Torah will be forgotten mean that there will be so much argument that it will be difficult to reach a consensus about the reasoning behind certain laws.
