Bava Metzia 10 - Shabbat March 9, 29 Adar 1

The Gemara quotes a Mishna in Peah 4:9 that describes someone who takes part in the corner of another's field on behalf of a poor person. Ulla and Rav Nachman disagree about whether the debate Mishna in Peah is only when a wealthy person takes the item for the poor person or even a poor person for a poor person. Rav Nachman raises a difficulty with Ulla’s ruling from our Mishna. How do Ulla and Rav Nachman understand the case in the Mishna differently to correspond to their understanding of the Mishna in Peah? A creditor cannot ask someone else to collect a debt when the debtor also owes others and may not have enough funds for all the creditors as they are causing a loss to others. Only the creditor him/herself can collect the loan. Does that concept apply to a lost item since potentially it is causing everyone else not to acquire it or since there is no potential financial loss for anyone as the lost item wasn't something they are owed, one can acquire it for a friend? Rav Nachman and Rav Chisda disagree with Rabbi Yochanan on this issue. The Mishna rules that one who jumps on an item does not acquire it. Reish Lakish brings a halakha in the name of Rabbi Abba Bardala Cohen that one acquires everything within the four cubits surrounding a person. A difficulty is raised against this statement from both a Mishna in Peah and our Mishna and three answers are brought for each source to explain why it does not contradict, the first is rejected and the last two are accepted. Reish Lakish and Rabbi Yochanan debate whether a minor girl's divorce document can be given to her by placing it in her courtyard or in the four cubits surrounding her. The first suggestion is that the argument is based on whether a courtyard functions as an extension of one's hand or as a messenger. However, this is rejected.
