What does "zrok li" (throw it to me) mean when repaying a loan? The Gemara (גמרא) analyzes whether this creates an obligation of actual receipt or merely requires doing what the lender requested with his money. The shiur unpacks Tosfos's challenge to Rabbeinu Tam and the fundamental machloket about yochol v'natko—whether it's a deficiency in nesina or a question of what constitutes a single object in halacha (הלכה).
This shiur analyzes a fundamental sugya in Gittin 78b exploring the meaning of "zrok li" (throw it to me) in the context of repaying a debt and the parallel din in hilchos gittin. The Gemara (גמרא)'s core question is whether "zrok li v'tipater" (throw it to me and you'll be discharged) requires actual receipt of the money or whether it constitutes a different form of payment—doing what the lender wants with his money. The shiur develops two distinct approaches to understanding repayment of a debt. One possibility is that the borrower must actually return the money to the lender—a true piron (repayment). Alternatively, the lender might accept something else: the borrower doing what the lender requests with the money, which serves as mechila (forgiveness) or an equivalent form of discharge. The example is given: if a lender says to give the money to charity instead, is that genuine repayment or a substitute arrangement? These represent fundamentally different legal categories—one is actual receipt, the other is discharge through compliance with the lender's request.

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.
