Different forms of Kashering

Why we check our garments before Shabbos

1. It’s a nice stirgnency for Tahor people not to consume Tamei food, and the mishna didn’t even bother discussing that, bc people keep that. (The mishna added that a zav and Zava who are both tamei shouldn’t eat together so they don’t end up sleeping together) 2. The rabbis advise against a Torah scholar who is tamei from eating with an ignorant tamei person- either bc the ignorant person may not...

1. A person is allowed to walk out with Tefillin on close to Shabbos and there is no decree that he may come to carry them on Shabbos, bc Tefillin one is always cognizant they are on him. This is rooted in the law that one is actually obligated to touch his Tefillin when they are on. It’s derived as kal vachomer from the tzitz of the Kohen Gadol. 2. One can’t take louse off clothing on Shabbos nex...

1. The rooftops in the city that people use should not be higher than the roof of the Shul. 2. The thoughts and considerations of the government are very deep. 3. It is good to fast the day one sees a bad dream, and even if that day is Shabbos. 4. In the middle of learning Torah, regular people need to stop for Shema and for davening times. But special ppl like R Shimon only stop for Shema and not...

1. One should wear shoes when davening. 2. There’s a dispute whether davening long is good if it takes away time from Torah study. 3. We mentioned One shouldn’t start judging a case close to Mincha but if they started they don’t have to stop. Starting is defined by putting on robes to judge, or it the judges were already wearing robes from Previous cases, then when the lawyers start arguments. 4....

1. There is violation against having any chametz on Pesach. The Rambam states that this is even for less than an olives worth of chametz. However, chametz mixtures that are in tiny proportions, or absorptions of chemetz in pots, one is allowed to keep them over Pesach. The restriction applies only to chametz that is real and tangible. Therefore, one is not required to sell or kasher any pots they...

1. In an alleyway that is walled on 3 sides and open on 4th side to the street- there needs to be a Lechi (vertical beam) in entranceway to permit carrying in the alley. However, one can only carry from the inner point of the beam and in, so the thickness of the entranceway itself would be forbidden to carry. One can also permit the alley with a korah- a horizontal beam that is on top of the alley...

1. If someone transferred a large basket that is the size of a “domain”- 10 tefachim high walls and 4x4 wide, they are exempt, (bc one is liable for transferring “items” like by the mishkan and not domains.) In circular basket, that requires 6 tefachim to fit 4x4 box inside. 2. If an item is not completely transferred into the second domain, one is exempt. So if someone transfers an 11 tefach High...

Ashes and Purity: an unlikely combination

The connection between Purim, Parah, and Carona

1. A very large enclosed field whose walls were not made for “dira” - for living purposes, the field is biblically considered a private domain (so if one threw in an item from the street they’d be liable) but the rabbis said it is forbidden to carry 4 Amos inside bc it’s like a kamelis. 2. The nooks off the street where traffic sometimes spills are Karmelis. The area between the pillars where merc...

1. Someone who carries from private domain to public domain but through a neutral zone- Ben azzai says he’s exempt and rabbis say he’s obligated. Ben azzai holds that מהלך כעומד דמי- each step in considered a new stop and go and it’s therefore viewed as one transfer from private domain to neutral zone and a second transfer from neutral zone to street. But the rabbis hold that as long as you don’t...

1. We are still trying to figure out why one is liable in the mishna for taking out or placing in a hand. A hand is not 4x4 tefachim and we assume we need 4x4 tefachim significance for akira and hanacha. The genara attempts to say our mishna is dealing with someone holding a 4x4 basket in his hand, or dealing with someone whose hand is within 3 tefachim of the ground, (someone bowing, standing in...

1. If someone stuck bread into an oven on Shabbos there is a predicament for what they should do. On the one hand, רדיית הפת- the art of taking bread out of an oven- is rabbincally forbidden on Shabbos. But if the bread is left in, the person will come to an violation of Shabbos when the bread bakes. The Gemara in unsure what the right thing is to do. However, another person is certainly NOT allow...

1. Usually, when the term "patur" is used in Maseches Shabbos, one is exempt but it is still rabbinically prohibited. However, this rule is only when there is some form of action involved. 2. When two people perform one melacha act together, like for example, one does the akira and one the hanacha, they are both exempt. This is derived from the reading of the Pasuk. 3. If one person placed an item...

1. To perform the biblical act of הוצאה, one must do both an “akira” (uprooting an time from its place) and “hanacha” (placing it “down” in the second reshus. 2. There are two forbidden types of “hotza’ah” (umbrella term for transferring items between private and public domain. One is the explicit issur in the Torah of taking from private domain and placing in public domain. The derivative is call...

1. Anyone who forces time, time pushes back on them. (Avshalom tried to prematurely take kingship from dovid and died). Anyone who is patient with time, time pays them back. We see this in story with rav Yosef and raba. Rav Yosef was ״Sinai” the one with more knowledge but Raba was “oker Harim,” the one with more analytical ability. It was determined that Sinai was greater but rav Yosef refused to...

1. In the beis hamikdash, they didn't say amen but rather "baruch shem" after brachos. Each bracha warrants a separate response. 2. We derive that one uses Hashem's name to great people from Boaz. Also from the angel who greeted Gidoen. The Gemara invokes the principle that there are times to forsake the Torah in order to uphold Hashem's wishes. 3. In a generation where the Rabbis aren't sharing T...

Why the real miracle of Purim really takes place before Purim

1. Stories in the gemara about talmidim following their teachers to the bathroom to study their conduct, as everything is Torah that needs to be learned. 2. One shouldn’t expose themselves until they are sitting down. One shouldn’t wipe with their right hand. There are five reasons- 1. Torah was given with Hashems right hand 2. Right hand used for eating 3. One ties Tefillin with right hand 4. One...

1. It says Hashem formed Adam, and the word formed (vayitzer) is spelled with two yuds bc we all have dual demands of either suffering from temptation or from following God. Alternatively, it is bc the first person, Adam ,was actually a male and female joined back to back. The Gemara notes that this is really a dispute- one opinion says male and female were originally one big figure, and another o...

1. When buying new home or clothing, one says שהחינו. If one already inherited a similar item or if he already bought a similar type of item, there’s dispute in the gemara whether שהחינו is still recited since it’s not as new to him. 2. We say הטוב והמטיב on good that has potential to be bad- like finding lost time that the King May interrogate him about. We say דיין האמת on and that has potential...

1. The constellation Ash is the tail of the Ram (aries=kimah). Ash is missing some stars. It happened bc when Hashem wanted to bring a flood to the world, he took two stars form Kimah, and to close the gap, he took two stars from the tail, Ash and closed it up. 2. Earthquakes come either from Hashem's two tears, or Hashem clapping His hand, Hashem kicking the sky, or Hashem pushing his feet under...

1.When Bavel will be destroyed, wild animals will come and harm its neighbors as well. When Shomron was destroyed, its neighbors were blessed, bc Shmoron become a place for planting fertile vineyards. 2. When someone sees large group of Jew (600,000) in Israel theres bracha that recited "the Sage of Secrets"- bracha is depicting how different each person is. 3. Ben Zoma noted how the difference in...
