How can a pregnant woman convert her unborn child when the principle is "ein shlichas lekatan" - there's no agency for minors? Tosafot offers two approaches: either conversion is only rabbinical for such cases, or the mother has total control (bailout) over the fetus, making agency unnecessary.
This shiur analyzes a complex sugya in Kesubos 11a regarding the conversion of minors, specifically focusing on the case of a pregnant convert (muberish nisgaira). The central question revolves around the principle of "ein shlichas lekatan" - that one cannot serve as an agent for a minor - and how this applies to conversion, which involves both benefits (zchus) and obligations (chov). Tosafot presents two approaches to resolve this difficulty. The first teretz holds that the conversion of a minor is only mid'rabbanan (rabbinical) because when there are both benefits and obligations involved, proper agency is required, which a minor cannot provide. Since the minor cannot appoint an agent, the conversion only works rabbinically. The second teretz maintains that conversion is a complete benefit (zchus gamur), making it valid mid'oraisa (biblical).

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.
