About this episode
Today's daf is sponsored by Eran Bellin and Marcy Goldstein in memory of Rabbi David Eliach. He was a founding member of the Yeshivah of Flatbush and taught generations of students to love Torah and serious study. A chicken that was trampled or thrown against a wall but managed to stay alive for 24 hours, can be slaughtered, but it should be checked after slaughtering that it had not become a treifa . Is it possible to slaughter on in that case on a Yom Tov? Should there be a concern that if it is found to be treifa, the slaughtering would have been performed for no reason, like the tiles that were heated up that may explode? A braita is brought regarding Shabbat, describing a case where there are several actions that if done by different people - one brings the fire, another the wood, the pot, the spices, etc., if you fire is brought first, all are liable – some for making a fire and some for cooking. The one who brought the pot – for what is he/she liable? This must be a new cauldron and like the tiles, by putting it on the fire, it is hardening it and preparing it for use. If there is a new oven, they are not muktze because it is possible to store things inside them, however, there are actions that should not be done with them because it is considered as preparing it for its first use. There are ways to remove animal hair but if done in the way the tanners do, it is forbidden. Do not cut vegetables with the type of scissors that are used to cut things from the ground because it will look like it was taken from the ground. But it is possible to do things that are a lot of work such as baking in a really big oven or cooking vegetables that require a lot of cooking. The Gemara brings a few more braitot that record permitted/forbidden actions in connection with food preparation. You can go to the muktze (the roof where the fruit is dried) before Shabbat even if the fruits are not fully dried and say that you want to eat from there the next day if it is the shemita year when you do not have to tithe the fruits. The Gemara brings two Mishnas that discuss what determines one's obligation to tithe the produce tithe – when the food is ready for use ( gmar melacha ), when it is brought into the courtyard, and also planning to eat them on Shabbat (because every meal on Shabbat is considered a meal, even if it is just a snack because of the verse "and you called Shabbat oneg "). Rava asks Rav Nachman - since bringing into the courtyard does not obligate one in tithes unless the fruit is ready for use, does Shabbat determine tithes only if the fruit is ready to be eaten? Rav Nachman says that Shabbat determines in any case. Mar Zotra tries to prove this from our Mishnah but the Gemara rejects his proof.
