Why do the Tosafos (תוספות) rule that a *chalal* who gets mixed up creates a *safek safeka* for his wife's status? The standard principle is that *safek echad b'guf, safek echad b'taruvos* cannot generate a *safek safeka*. The shiur explores the Beis Meir's novel distinction and the Avnei Milu'im's critique.
The shiur analyzes a fundamental question on Tosafos (תוספות) in Kesubos 14a regarding the application of *safek safeka* principles. The case involves a *chalal* (ritually disqualified priest) who becomes mixed up with another person, creating uncertainty about his wife's status for *kehuna* (priestly marriage). Tosafos rules this constitutes a valid *safek safeka*: perhaps she didn't have relations with the *chalal* at all, and even if she did, perhaps he wasn't really a *chalal*. However, this appears to contradict the established principle of *safek echad b'guf, safek echad b'taruvos* - when one doubt concerns the object itself and another concerns mixing, there's no valid *safek safeka* because the doubts weren't simultaneous.

Dedicate a Shiur in Gemara
L'ilui nishmas a loved one. In honor of a simcha or yahrzeit. As a zechus for a refuah sheleimah. Your dedication helps carry Rabbi Zweig's Torah to learners around the world.
When an animal damages crops, the Torah prescribes a unique payment formula based on multiplying the damaged area by sixty. Does this formula redefine the actual loss, or does it merely create a payment mechanism that still acknowledges the full damage sustained? The Gemara explores whether someone who ate in doubt should pay the higher-quality amount, examining how the principle of motzi me-chaveiro alav haraya applies when payments fall within the range of actual loss.
What makes testimony valid when different witnesses testify to different parts of the same event? The Gemara debates whether the principle of "davar v'lo chatzi davar" (complete testimony, not partial) disqualifies witnesses who testify separately to theft and slaughter. Rashi's approach reveals that the issue is not merely combining elements, but whether each witness's statement is independently meaningful.
Why is a ganav who sells a stolen animal on Shabbos exempt from the fourfold/fivefold payment? The shiur analyzes whether this exemption stems from kam lei b'derabbah or from the absence of a valid mechira. The Rashba's principle that matana resembles mechira when it is "nishtarish b'chet" is explored, along with the Rambam's position on hekdesh and the distinction between giving to bedek habayis versus mizbe'ach.
When a ganav shechts a stolen animal l'avodah zarah, why isn't he patur from payment since it's already isur hana'ah? The shiur explores the fundamental machloket Rashi-Tosafot on whether the isur derives from the act of shechita or from the din shechita itself. The Gemara's application of davar garem be'mamon ke'mamon domi extends the analysis to when borrowed animals become niskal.
