Walking on the rosd

1. For most liquids the size for carrying is a רביעית, but for wine it is a 1/4 of a רביעית. The reason given is that it is used for כוס של ברכה. Rava understands that undiluted strong wines are meant to be mixed with 3x water, so a 1/4 wine will total a full reviis after mixed. This fits with the law that all liquids are a Reviis. Acc to rava, our mishna is proof that כוס של ברכה is a רביעית. Aba...

Why the desert is chosen for Torah

1. There are different sizes for various items to be considered significant in regard to carrying. If one carries an insignificant item, they are exempt from a Korban. For example, all human foods are significant if they are the size of a dried fig, but animal foods have different sizes. (Processed straw the amount to fill mouth of a cow, straw from beans the amount to fill mouth of a camel, unpro...

Prep for shavuos

1. Ripping in order to fix is קורע, as in the mishkan they ripped curtain that worms had made holes inside before repairing them. 2. Even just stretching a thread to tighten connection between two pieces of garment is a form of sewing. 3. It is forbidden to converse with a heretic. It is not forbidden to converse with a sorcerer. 4. It is a mitzvah to engage in astronomy and other science in order...

The two covers of the tachash and techeles

1. זורה, בורר, מרקד are essentially the same act of labor as they all spectate undesired parts. They are are still categorized as separate melochos bc they are distinct acts that were done for the mishkan. 2. There something called כותש- pounding the grain to remove some bran stuck to the inside kernel. (It’s very similar to the melocho of threshing) This is not mentioned in the Mishna bc a poor p...

Why going to eretz yisroel is harder than leaving mitzrayim

1. Misasek is exempt from a Korban. If someone didn’t intend for the action at all, clearly that’s misasek. But if they intended for the overall action, but in a muttar format, and inadvertently performed it in an assur way, Abaye says it’s not misasek and there is an obligation to bring a Korban. Rava says it is still misasek. 2. There are 3 examples of this dispute. Someone intends the cut a det...

1. There is a unique sin for sleeping with a שפחה חרופה- a slavewoman betrothed to a Hebrew slave. It is treated differently from regular adultery and the punishment is a Korban asham. Usually a sin offering is only for unintentional sin, but here, the Korban is brought for intentional and unintentional sin alike. A Korban asham is very similar to a Korban chatas, but it is a different type of Kor...

The 10th animal is holy naturally

1. In general, if someone does the same sin twice in one lapse of awareness, one Korban suffices for both actions. 2. On Shabbos, there are two different forms of שוגג- forgetting Shabbos and forgetting that a particular melocho is assur. Theoretically, one can perform the same melocho twice without realizing he sinned but with both forms of Shogeg. The case is someone was initially aware harvesti...

Raben Gamliel

The depth of one man tripping over his brother

1. There are 39 categories of forbidden melochos on Shabbos. The number 39 is derived from אלה=36 + דברים= 2 + *ה*דברים=1. 2. Although logically one would think the 39 melochos are different forms of the same sin (and therefore one who violates multiple melochos should bring just one Korban) we derive that actually each melocho is distinct and requires it’s own Korban. 3. This concept of חילוק מלא...

Struggling with the Torah

1. Munbaz derives from the comparison between Shogeg and meizid that one is Shogeg even when they know the sin is forbidden. As long as they are unaware of the consequences of sin, like the obligation to bring a Korban after sinning, they are called Shogeg and must bring a Korban. The rabbis disagree and say Shogeg about consequences is not Shogeg. Shogeg is only when the person is unaware of the...

How r shimon saves every Jew

1. Our perek is called כלל גדול- the big rule. We refer to it as a big rule bc other rules that appear in mishanyos are not as broad as hilchos Shabbos that can apply to plants even detached from the ground. There is another כלל גדול in maseches sheviis bc the laws of Shemita are broader than the rule of maaser, as shemita applies even to animal food. Some have text of כלל גדול by maaser bc its la...

White fire in the Torah

1. The Gemara describes a therapy for a bad fever that involves using a thornbush and referencing the story of Moshe and the burning bush. Hashem used the thornbush bc it is so low and humble. Other therapies for boils, blisters, and demons are described. 2. Mishna permits anyone to go out with gold bells that princes go out with. Why aren’t we scared they will be taken off in the street bc they d...

Hod of hod

1. R Meir allows an amputee to go out with a wooden bottom fake leg. This leg is “like his shoe”, as it covers up that he’s missing a foot. R Yosi forbids this. The Gemara has much discussion whether the opinions are actually reversed, but this is the outcome of r Yosi forbidding. 2. This dispute between r Yosi and r Meir is relevant also in the laws of chalitza, when the woman takes off her broth...

*דף סה* לע״נ הענטשע בת שמואל 1. When there a prohibition of מראית עין, there’s a dispute if the rabbis forbid it even in secrecy or only in front of people. Example is spreading out wet clothes on Shabbos where ppl can’t see, but if they did, they may think he’s wrongly done laundry on Shabbos. 2. Wad in ear for dripping wax is ok only if it’s tied to the ear. R Yochanan was lenient if it’s insert...
