Previous daf Yevamos 20
According to Rebbi Shimon, Eishes Achiv she'Lo Hayah be'Olamo who was born
after the second brother performed Yibum, is permitted, because he found her
be'Heter when he was born.
Why do we say that S'vara here, and not by his
maternal sister, whose paternal brother married her before he was born, and
who now falls to Yibum?
(a) What is an ...
(b) What is the Halachic difference between an Isur Ervah on the one hand,
and an Isur Mitzvah and Isur Kedushah on the other (regarding Yibum)?
- ... Isur Mitzvah?
- ... Isur Kedushah?
(a) 'Almanah le'Kohen Gadol, Gerushah va'Chalutzah le'Kohen Hedyot'.
is it possible for a Gerushah to fall to her husband's brother who is a
Kohen, to Yibum?
(b) Was an Isur also performed in the case of Almanah le'Kohen Gadol?
(c) Which other cases of Chayvei La'avin are listed in our Mishnah?
(d) From where do we learn that Chayvei La'avin fall to Yibum in the first
place, seeing as they are forbidden to perform Yibum?
(a) The Mishnah opens with the words 'K'lal Amru bi'Yevamah, Kol she'Isurah
Isur Ervah'. Rafram bar Papa explains that this comes to include Tzaras
Aylonis in the Din of Isur Ervah, like Rav Asi above (12a).
What is wrong with saying that, according to Rebbi Yehudah, Isur Sh'niyos
are referred to as 'Isur Kedushah' because anyone who fulfills the words of
the Chachamim is called 'holy'?
How do others
(b) What does our Mishnah mean when it says 'Achosah she'Hi Yevimtah,
Choletzes O Misyabemes'? Why must the Tana be referring to the sister of
Isur Ervah (at the beginning of the Mishnah), and not to the sister of Isur
Mitzvah (which precedes it)?
(c) Why does the Tana refer to ...
(d) Rebbi Yehudah in a Beraisa switches the descriptions.
- ... Sh'niyos as 'Isur Mitzvah'?
- ... Almanah le'Kohen Gadol etc. as 'Isur Kedushah'?
him, why does the Tana refer to ...
- ... Almanah le'Kohen Gadol etc. as 'Isur Mitzvah'?
- ... Sh'niyos as 'Isur Kedushah'?
(a) An Almanah le'Kohen Gadol incorporates both the La'av of "Almanah Lo
Yikach" and an Asei.
Answers to questions
What is the Asei?
(b) What is then the problem with the presumption that we are talking about
both an Almanah who was *married* who fell to the Kohen Gadol, and one who
was only *betrothed*?
(c) How do we initially resolve this from the superfluous word "ve'Alsah
(d) And from where do we know that this D'rashah does not incorporate
(a) On what grounds do we include Chayvei La'avin (from "Yevimto") for
Chalitzah only, but preclude Chayvei Kareis (from "Im Lo Yachpotz")?
(b) If a Yavam performs Yibum with a Chayvei La'avin, does he acquire her
(according to our current theory)? Is her Tzarah now free to marry le'Shuk?
(c) In that case, how does Rava explain the Beraisa 'Isur Mitzvah ve'Isur
Kedushah *Ba Alehah* O Chalatz Lah, Nifterah Tzarasah'?
(d) What does the Beraisa say with regard to a P'tzu'a Daka, a K'rus
Shafchah or a S'ris Chamah (all of whom are forbidden by a La'av to marry a
Kasher Jewess) that repudiates the current theory (that Chayvei La'avin
cannot perform Yibum mi'd'Oraysa from "Yevimto")?
(a) What does the Tana of the Beraisa mean when he says with regard to the
aforementioned Chayvei La'avin 'O Choltzin O Meyabmin'?
(b) Why does the Tana include a Zakein in the list? Is he also among the
(c) The Tana also adds that Ma'amar, a Get and Chalitzah are all effective.
In what way is a Get effective on a Yevamah? Does it allow her to marry
(d) Is he permitted to remain with the Yevamah, if he performed Yibum ...
- ... with Chayvei La'avin?
- ... with a Zakein?
(a) We now see from the Beraisa that Chayvei La'avin are also subject to
Yibum min ha'Torah. According to Rava's initial contention, Chayvei La'avin
may perform Yibum, and Almanah le'Kohen Gadol is different, because there is
also an Asei.
(b) Why can we not preclude Mamzeres and Nesinah from Yibum because they
too, are included in the Asei of "ve'Hiskadishtem" in Shemini?
(a) According to Rava's next contention (that Chazal forbade certain cases
of Chayvei La'avin because of a decree), why can the following not perform
(b) According to that, why do we not decree ...
- ... Almanah min ha'Eirusin?
- ... Mamzeres u'Nesinah?
(c) What is the discrepancy between what we just said and the fact that a
Mamzeres and Nesinah le'Yisrael cannot make Yibum?
- ... the wife of his paternal brother on account of his maternal brother?
- ... a woman who does *not* have children on account of one who *does*?
- ... the wife of a brother who *lived* at the same time as the Yavam, on accouont of one who did *not*?
- ... all women who can have children on account of an Aylonis?
(a) What reason does Rava finally give for Chayvei La'avin's preclusion from
(b) Rava retracts however from this (in spite of a Beraisa which supports
him), due to a statement made by Resh Lakish (though others ascribe this
Kashya to Rav Ashi).
(c) What alternative does the Yavam have here (that makes Yibum comparable
to Resh Lakish's ruling)?
(d) How is Rava's Kashya rejected from the Beraisa 'Im Ba'alu, Kanu'?
(a) Rebbi Yochanan and Rebbi Elazar argue over whether the Yibum performed
by a Kohen Gadol on his Yevamah who is an Almanah exempts her Tzarah from
Answers to questions
Which kind of Almanah are they arguing over? What is the basis of
(b) The Beraisa of 'Im Ba'alu, Kanu' proves that Chayvei La'avin are in
fact, subject to Yibum min ha'Torah.
Why does it not also prove Resh
Lakish (who says that whenever one has the fulfilling the Asei without
negating the La'av, one is obligated to do so) wrong? Why do we not force
the Yavam to perform Chalitzah?
