Question: Our Tana holds that Isur Chal Al Isur regarding Isur Kolel (the latter Isur forbids also other matters), Isur Mosif (it forbids the forbidden matters to more people or in more ways) and Isur Bas Achas (two Isurim that take effect simultaneously). Like whom is this?

Answer #1 (Rav Yehudah): It is R. Meir.

(Beraisa): One can bring four Chata'os and one Asham for one Achilah, e.g. a Tamei who ate on Yom Kipur Chelev (forbidden fats) that was Nosar (past the allowed time) from a Korban;

R. Meir says, if it was Shabbos, and he took the food in his mouth from a Reshus ha'Yachid to a Reshus ha'Rabim, he is also liable for this!

Chachamim: That is not relevant to liability for eating.

Question: Like whom does R. Meir hold?

He is unlike R. Yehoshua, who exempts from Chatas one who mistakenly errs while engaging in a Mitzvah!

Answer #1: He holds like R. Eliezer.

Answer #2: He can hold even like R. Yehoshua:

R. Yehoshua exempts one who circumcised the wrong child on Shabbos, since he is frenzied to do the Mitzvah in time. In our case, he is not rushed.

Question: There is no time pressure regarding Terumah, yet R. Yehoshua exempts!

(Mishnah): If a Kohen was eating Terumah and learned that his mother was divorced or did Chalitzah (i.e. he is a Chalal; he lacks Kedushas Kehunah), R. Eliezer obligates him to pay principal and a fifth (the fine for a Zar who ate Terumah);

R. Yehoshua exempts.

Answer (Rav Bivi bar Abaye): The case is, he was eating (Chametz) Terumah on Erev Pesach, when there is time pressure.

Answer #2: It suffices to say that our Tana holds that Isur Chal Al Isur when they are Bas Achas, like R. Shimon.

Question: Granted, the Isurim of Eshes Ish, Eshes Ach and Achos Ishto come simultaneously if the brothers made one Shali'ach to Mekadesh, the sisters made one Shali'ach to receive Kidushin, and the Kidushin moneys were given together.

However, how can the Isurim of Nidah come simultaneously with the other Isurim?

Answer (Rav Amram): They were Nidah when the boys became (adults, at) 13, so the boys' Isurim came simultaneously;

The girls were Nidah when they became 12, so their Isurim came simultaneously.

(Mishnah): We separate them (lest they are pregnant)...

Question: A woman cannot become pregnant from her first Bi'ah!

Answer (Rav Nachman): They had Bi'ah twice.

Question: R. Chiya taught that 16 Korbanos Chatas are brought. If they had Bi'ah twice, there would be 32!

Counter-question: You must agree that according to R. Eliezer, who is Mechayev for each pleasurable action during Bi'ah, they are liable more than 16!

Answer: You must say that we count only the Chata'os for the first act.

Answer: Likewise, we count only for the first Bi'ah!

Question (Rava): Tamar became pregnant from her first Bi'ah!

Answer (Rav Nachman): She enabled this through crushing her Besulim with her finger.

(R. Yitzchak): All girls of Rebbi's house who did this were called Tamar.

Question: Her first Bi'ah was not with Yehudah. She had previously married Er and Onan!

Answer: Er and Onan had Bi'ah she'Lo k'Darkah (in the anus) with her.

Question (Beraisa - R. Eliezer): All 24 months (of nursing), her husband spills the semen outside (lest pregnancy cause premature weaning and death of the baby).

Chachamim: This is like Er and Onan (it is forbidden)!

Answer: It is like them in one respect, unlike them in another.

It is like them regarding "V'Shiches Artzah" (wasting seed);

It is unlike them regarding Lo k'Darkah. The Beraisa discusses Bi'ah k'Darkah.

Question: The above verse teaches about Onan. How do we know that Er did so?

Answer (Rav Nachman bar Yitzchak): "(Hash-m) killed also him" - he died for the same sin.

Question: Granted, Onan did so because he knew that the child would not be considered his (but rather, like his brother's). However, why did Er do so?

Answer: He did not want her beauty to be diminished through pregnancy.

(Beraisa - R. Yehudah): "(When a man has Bi'ah) Osah (with her, they become Temei'im)" - this excludes a Kalah (the first Bi'ah is not Metamei);

Chachamim say, this excludes Bi'ah she'Lo k'Darkah.

Suggestion (Hon, Rav Nachman' son): R. Yehudah holds that the Torah was concerned for a Kalah's make-up! (She may even touch Tahor food without Tevilah. Even though the Torah allows a Chatzitzah on the minority of the body, Tevilah would wash away her make-up.)

Rejection (Rav Nachman): No, it is because she cannot become pregnant from Bi'ah Rishonah.

Question: What is the source of the dispute?

Answer: Chachamim expound "Shichvas Zera" - to exclude Ha'ara'ah (the first stage of Bi'ah); "Osah" excludes she'Lo k'Darkah;

R. Yehudah excludes both of these from "Shichvas Zera". "Osah" excludes a Kalah.

(Ravin): If a woman was 10 years without a husband after she was once married, she will not give birth.

(Rav Nachman): If she was planning to remarry, she can become pregnant.

(Rava married Bas Rav Chisda more than 10 years after she was widowed.)

Rava (to her): Chachamim suspect you (that you had Zenus in the interim, and this preserved your fertility)!

His wife: I was planning to marry you.

A woman (to Rav Yosef): I waited 10 years before remarrying, and I gave birth!

Rav Yosef: Do not discredit the sages' words!

She admitted that she had had Bi'ah with a Nochri in the interim.

Version #1 (Shmuel): Any woman who had Bi'ah must wait three months before marrying someone else (to avoid doubts about who the father is if she will gave birth nine months later), except for a minor who converted or was freed from slavery;

A minor Yisraelis must wait.

Question: What is the case?

Answer #1: She did Mi'un (to leave a mid'Rabanan marriage).

Rejection: Shmuel says that she need not wait after Mi'un!

Answer #2: She was divorced.

Shmuel already taught that she must wait!

(Shmuel): If a minor did Mi'un, she need not wait three months. If he gave her a Get, she must wait.

Answer: She was Mezaneh.
