Ask A Question on the daf
Previous daf Yevamos 49
YEVAMOS 46-50 - Ari Kornfeld has generously sponsored the Dafyomi
publications for these Dafim for the benefit of Klal Yisrael.
1) WHAT MAKES A MAMZER?
(a) (Mishnah - R. Akiva): A Mamzer is the result of any
relations forbidden by Chayavei Lavin;
(b) R. Shimon ha'Timni says, Chayavei Kerisus;
1. This is the law.
(c) R. Yehoshua says, Chayavei Misos.
1. Ben Azai: I found a scroll of lineage in
Yerushalayim which says, Ploni is a Mamzer from a
married woman, to fulfill the words of R. Yehoshua.
(d) If a man's wife dies, he may marry her sister; if he
divorced her, then she died, he may marry her sister; if
she married someone else then died, he may marry her
(e) If a Yevamah died, the Yavam may marry her sister; if he
did Chalitzah and she died, he may marry her sister; if
she married another man and died, he may marry her
(f) (Gemara) Question: What is the source of R. Akiva?
(g) Answer: "A man will not take the wife of his father, and
will not reveal the wing of his father."
1. A wing that his father saw, he will not reveal.
(h) R. Shimon ha'Timni learns as Chachamim, that "wing of his
father" refers to a Shomeres Yavam of his father, which
is Chayavei Kerisus (since she was his uncle's wife).
2. R. Akiva holds as R. Yehudah, who says that this
verse refers to a woman raped by his father, which
is Chayavei Lavin.
3. Adjacent to this, it says "A Mamzer ..." - to teach
that from such relations come Mamzerim.
4. According to R. Simai, who says that even Chayavei
Lavin which are not because of kinship, and R.
Yeshevav, who says even Chayavei Ase - R. Akiva
learns from "*And* not" to include these cases.
1. Since the prohibition of a Mamzer is written next to
this, we see that Chayavei Kerisus produce Mamzerim.
(i) R. Yehoshua does not learn this way - if so, the Torah
should only have said "He will not reveal the wing" -
there was no need for the prohibition of a father's wife
in the verse!
1. Rather, the verse comes to teach, from Arayos as
severe as a father's wife (Chayavei Misos) until
(but not including Chayavei Kerisus), Mamzerim
(j) (Abaye): All admit that a Mamzer does not result from
relations with a Nidah or a Sotah.
2) WHY MENASHE KILLED YESHAYAHU
1. (The children are not Mamzerim) by a Nidah - since
she can be married.
(k) A Beraisa supports Abaye.
i. "*u'Tehi* (and will be) her impurity on him" -
even when she is Nidah, Havayah (engagement -
the word has the same root as u'Tehi') takes
effect on her.
2. Also by a Sotah, marriage takes effect.
1. (Beraisa): All admit that the child of a Nidah,
Sotah, or a Shomeres Yavam (that conceived from a
stranger) is not a Mamzer.
(l) (Beraisa - Shimon Ben Azai): I found a scroll of lineage
in Yerushalayim, that said that Ploni is a Mamzer from a
i. Abaye did not teach the case of Shomeres Yavam
- he was unsure if the law is as Rav (who says
that a marriage does not take effect to a
stranger) or as Shmuel (who says that perhaps
the verse only comes to prohibit relations
with a stranger).
(m) The scroll also said, the teachings of R. Eliezer Ben
Yakov are few but clean (the law is always as him);
(n) It also said, Menasheh killed Yeshayahu.
(a) (Rava): He judged him and killed him.
(b) Menasheh: Moshe, your Rebbi, said "A person will not see
me (Hash-m) and live" - and you said, "I saw Hash-m
sitting on an exalted throne"!
1. Moshe, your Rebbi, said "Who is as Hash-m, our L-rd,
whenever we call to him" - and you said, "Seek
Hash-m when he is found"!
(c) Yeshayahu reasoned: I know, he will not accept my answers
- if I answer, I will make him an intentional sinner!
2. Moshe, your Rebbi, said "The number of your days I
will complete" - and you said, "I will add 15 years
to your days"!
1. Yeshayahu said a name of Hash-m, and was swallowed
into a cedar tree. They brought the tree and were
sawing it. When they got to the place of his mouth,
he died, because he had said (earlier) "I dwell
among a people of unclean lips".
(d) Question: How can we resolve the questions Menasheh
(e) Answer: "I saw Hash-m" - as a Beraisa teaches, all
(other) prophets saw Hash-m through a glass that does not
illuminate; Moshe Rabbeinu saw through an illuminating
glass (only Moshe realized that he did not really see
1. "Seek Hash-m when he is found" - he is always found
to a congregation, but not always to an individual.
(f) "I will complete the number of your days" - Tana'im argue
i. Question: When is Hash-m found to an
ii. Answer (Rav Nachman): The 10 days between Rosh
Hashanah and Yom Kipur.
