About this episode
Presentation Study Guide Yevamot 8 Today's daf is sponsored for a refuah Shleima to Dr. Joakim Isaacs, Avraham Chaim ben Fruma, a seasoned Daf Yomi learner, from the Isaacs and Darshan Families. Today's daf is sponsored anonymously in loving memory of Moshe ben David Rav Moshe Feinstein. Today's daf is dedicated by Marcia Baum in honor of the birth of her granddaughter Moriah Nava born to her children Jessica and Jeremy Miles. "How wonderful that this little girl has been born in an age when Gemara learning for girls is acceptable and encouraged by many!" The Gemara rejects the comparison of Ulla of yibum to a leper who has a seminal emission because the leper has a moment where he is permitted before he has the seminal emission, whereas in the case of yibum there is not always a time when the woman is permitted to do yibum with the brother (depending on the order of events). It is possible the drasha of " aleha " is necessary in a case where it can be compared, in which the woman fell to yibum before her sister married the brother. Another suggestion as to why the drasha was necessary is that one could have learned from a heikeish that all forbidden relationships are compared to his brother's wife, in which yibum would be permitted in them all. Alternatively, Rava suggests that the verse did not even come to forbid the forbidden relative – that was clear - the drasha was meant for the tzara , the second wife. A number of questions are raised against Rava, but are answered. If it is so clear that they will not allow forbidden relations in yibum , why should it not be clear (why a drasha is needed) to teach that even the second wife can't do yibum ? Rami Bar Hama also raises a question against Rava and there is a back and forth between them. Rav Ashi asks about the drasha of " aleha " and asks maybe the drasha should come to teach that when there is a mitzvah, yibum , both the forbidden relative and the second wife will be permitted? What is derived from the expressions "and he shall take her" and "he shall perform levirate marriage with her" both according to the Rebbe and according to the rabbis?
