Rabbi Baruch Bodenheim: Wednesday Night Gemara Shiur Bava Metzia 30A: Raah Mayim She Shotfin (07/18/2012)

Learn Gemara 31a “Raah ..”(end of 4th line from the top) until second set of two dots
Questions;  What is the conclusion of the gemara in regards to Hashovas aveida on land? Ritva “Mahu”
When one removes a cow that is grazing in a vineyard of a Jew to prevent the animal from damaging the vineyard is he now obligated to return the cow or not? Ritva “Ha”, Rosh siman 22
Point to ponder; According to Rava when the torah includes Hoshavas aveida on land is that just for the prohibition of “Lo suchal Lihisalem” or also for the Mitzva of ” Hashev Teshivim”?
