Study Guide Yevamot 34 This week's learning is sponsored by Sharon Hirsch in honor of her daughter, daughters-in-law and granddaughters. Today's learning is sponsored by Rikki and Alan Zibitt in loving memory of Rikki's mother, Frieda Carlin, Fraidl bat Meir v'Rivka on the occasion of her 7th Yahrzeit. May her neshama have an Aliyah. After discussing the different opinions of Rabbi Shimon and Rabbi Yosi regarding actions that could possibly incur multiple prohibitions, the Gemara associates our Mishna with the opinion of Rabbi Meir who holds that in cases of prohibitions that are inclusive (issur kollel) and ones that are expanded (issur mosif) and ones that happen at the same time, one is obligated for each one (issur chal al issur). This is proven by a Mishna in Keritot regarding an impure person who ate on Yom Kippur forbidden fats from a sacrifice that were leftover beyond their time (notar) – they are obligated to bring four sin offerings and one guilt offering. Rabbi Meir there adds that if it was Shabbat and the person was eating it as they walked out on one domain and into another, they would be obligated as well for carrying on Shabbat. This case includes all three types. How does the ruling regarding the mistake in the kiddushin relate to a debate regarding one who makes a mistake while performing a mitzva? The Gemara suggests that the Mishna could also be explained according to Rabbi Shimon if it can be explained that all the prohibitions came simultaneously. Rav Amram brings a possible scenario in which this could be. There is an assumption that women can’t (or likely do not) get pregnant the first time they have sexual relations. If so, why does the Mishna rule that the woman needs to wait three months before going back to her actual husband? An answer is brought to resolve the question. Didn’t Tamar get pregnant during her first time having relations? Firstly, the Gemara establishes how they know she was still a virgin. Then they resolve the question. Another issue regarding impurity that relates to the assumption that women don’t get pregnant from their first time having relations is discussed. Rabbi Yochanan said that a woman who was married and the marriage ended and she waited more than ten years before getting remarried, could no longer bear children. However, Rav Nachman limits this to one who did not have a desire to get remarried during that time. A few cases of this are brought including Rav Chisda's daughter’s marriage to Rava which was after ten years of her being married to Rami bar Hama, and yet she bore children from that marriage. What women do not have to wait three months before remarrying?
