If a slave is used as a designated payment for a loan (apotiki) and the master frees the slave, the slave has no responsibility to the creditor. However, the rabbis instituted a takana and force the master to free him. To compensate the creditor, the slave writes a promissory note for his value. Rabban Shimon ben Gamliel holds that the one who frees the slave writes the promissory note. Rav and Ulla each explain this case differently. Which master freed the slave, which master needs to free the slave and who writes the promissory note according to Rashbag? What is the purpose of the takana and what is the root of the debate between tana kamma and Rashbag? If one designated a field to repay and loan and the field is damaged, can the creditor collect from other property of the debtor? On what does it depend? If a slave is half freed, Beit Shamai and Beit Hillel disagree about whether or not the owner needs to free the other half. In the end, Beit Shamai convince Beit Hillel that we need to free the slave in order to permit him to marry a woman so he can fulfill the mitzva of procreation. Can one free a slave partially? There is a debate between Rebbi and the rabbis about whether this works. Raba and Rav Yosef disagree about whether the debate relates only to a slave freed by a document or also by money.
