The Every B-S-I-T edition presents an audio series on the תלמוד בבלי, focusing on מסכת בבא בתרא. This particular מסכת, the longest in terms of pages in ש''ס, has been dedicated by our esteemed friend and pioneering student of the דף יומי שיעור, אהרן עזרא השם ישמרהו ויחייהו, for the הצלחה of his dear children. May they grow to bring him much נחת, be blessed with חכמה בינה ודעת, and, בעזרת השם, may they be זוכה at the right time to proper זיווגים and to wealth and honor from now until eternity. A prayer is also offered for his wife and entire family, אמן.
Today's study of Bava Batra begins on דף צ' and will focus on פ''ט עמוד ב', starting twelve lines from the bottom. The text states: אמר רב יהודה אמר רב: אסור לאדם שישהה מדה חסרה או יתירה בתוך ביתו. A person is prohibited from keeping a measure that is either deficient or excessive in his house. The concern is that he might inadvertently use it, leading to potential cheating. Even if it is a urinal, the concern remains. One might wonder who would use such an item, but in a moment of need, a person might clean it and repurpose it. Thus, even a urinal is not exempt from this prohibition.
The רשב''ם explains that the prohibition is in place because sometimes a person may mistakenly use the faulty measure. However, the Torah's prohibition only applies when the measure was acquired with the intent to deceive. If not, one might ask why such a prohibition is necessary. The text clarifies that even in the case of a urinal, there is a risk that it will be cleaned and used for measuring. Therefore, the only solution for these faulty measures is to break them. The גמרא elaborates on this with several conditions.
אמר רב פפא: לא אמרן אלא באתרא דלא חתימי. This ruling applies only in places where there is no customary sealing of the measures. In regions where seals are used, there is no concern, as people will recognize that an unsealed measure is not legal and will avoid using it. The רשב''ם adds that in places where the king's officials do not put seals on measures, it is prohibited because it could lead to deception.
Even in places without seals, the text states: ואפילו באתרא דלא חתימי, לא אמרן אלא דלא מהנדסי. This indicates that the prohibition only applies in locations where there are no officials monitoring the measures. If officials are present to check the measures, there is no concern, as they will prevent any misuse of unsealed measures. The Gemara warns that during busy times, such as between sunset and nightfall, there is a risk that someone might mistakenly use a faulty measure without realizing it.
The Gemara further supports this with a ברייתא stating: לא ישהה אדם מדה חסרה או יתירה בתוך ביתו, ואפילו יעמיד שם מי רגליים. A person should not leave an undersized or oversized measure in his house, even if it is used for a urinal. The discussion then shifts to proper measurements for dry goods, listing various sizes such as סאה, תרקב, and others, along with their equivalents.
As the discussion proceeds, the Gemara outlines the various measurements used for dry goods and their proper standards. The רשב''ם clarifies that a סאה is equivalent to six קבין, and a תרקב is two קב. Each measurement is carefully detailed to prevent any confusion or misuse in commercial transactions.
When it comes to liquid measurements, the Gemara states: ובמידה הלח הוא עושה. The appropriate liquid measures include הין, חצי הין, and others, each with specific volumes. The רשב''ם elaborates that a הין is equivalent to twelve לוג, connecting the dry and liquid measurements through their ratios.
The discussion continues with the rationale behind certain measurements and why they were established in this manner. The Gemara emphasizes that maintaining accurate measures is crucial to prevent deceit in trade. As the conversation unfolds, the Gemara addresses the need for clear distinctions between different measures, highlighting the importance of accurate weights and measures in all transactions.
In conclusion, the Gemara underscores the significance of adhering to proper measurements, both in dry and liquid goods. The careful delineation of these measurements serves to protect consumers and maintain fairness in commerce. The standards established in the study of these halachot remain relevant, ensuring that integrity is upheld in all transactions.
