Presentation in PDF format Today's daf is dedicated by Dvoranit Shwartz in honor of the successful fundraising campaign for Shirat HaTamar shul in Efrat and with deep appreciation for the Rabbanit of the kehilla, Shira Merili Mirvis. A braita lists several cases where one could potentially have to do chalitza for one's mother, sister or daughter out of doubt. Under what circumstances would this happen? Other unique situations are described in another braita - where a couple could have five children, each having a different status - convert, gentile, slave, mamzer and Israelite. How? Another riddle - one could have to sell his father, who is a slave, to pay back his mother's ketuba. How? What does this teach you about the status of slaves and can they be mortgaged for a ketuba? The Mishna described more situations in which two children are mixed up at birth, one is the nephew of the other. What are laws of yibum/chalitza for them and their brothers? If the son of a woman married to a kohen got mixed up with the son of a maidservant in his household, what is that son allowed/not allowed to do? He is considered a kohen out of doubt so he needs to be strict regarding stringencies of kohanim, however, with regard to monetary issues we are lenient based on the principle "hamotzi m'chavero alav hareaya", the burden of proof lies on the one trying to claim the money. Rabbi Yosi and Rabbi Yehuda disagree about whether a slave can collect teruma from the granary. The concern is that people will see him and think he is a kohen and marry him off, not realizing he is a gentile slave who cannot marry a Jew. Rabbi Yosi permits as in his town, they don't allow people to marry based on seeing them on the line to collect teruma. Rabbi Yehuda forbids as they permit testimony from the teruma line for marriage purposes. Who else is not allowed to collect teruma from the granary?
