A case occurred, a man's conduit for seed was closed, and it would come out through the place for urine. Rav Bivi bar Abaye intended to rule that he is Kosher.\Chazon Ish 12:7

Objection (Rav Papi): This cannot be! Seed is cooked only in its proper conduit (so he cannot have children)!

(Rav Yehudah citing Shmuel): If the Ever was punctured and sealed, if the seal tears during an emission of semen, he is (sterile and) forbidden. If not, he is Kosher.

(Rava): This cannot refer to a puncture below the crown. There, even if cut, he is Kosher!

Rather, the puncture is in the crown itself.

(Rav Mari bar Mar citing Shmuel): If the crown was punctured and sealed, he is forbidden only if the seal tears when he has an emission.

Question (Rava brei d'Rabah): How do we cause him to have an emission to check this?

Answer #1 (Rav Yosef): We put warm barley bread by his anus.

Objection (Abaye): Is everyone like Yakov Avinu, who called Reuven "My first strength" because he never had an emission before that?!

Answer #2 (Abaye): We pass colored women's clothing in front of him, and this causes him to have an emission.

Objection (Rava): Is everyone (steeped in lust) like Barzilai ha'Gil'adi?! (This is not enough to cause an emission!) Rather, we do like Rav Yosef said.

(Beraisa): If it is punctured, he is forbidden, because the seed drips out. If it is sealed, he is Kosher, since he can have children. This is a disqualification that can revert to Kashrus.

Question: Which case does 'this' exclude?

Answer: It excludes a scab that developed over a bruise. This is not a proper sealing.

Question (Rav Idi bar Avin): How do we seal a puncture?

Answer (Abaye): We cut around the puncture with barley and rub the area with oil. We bring a big ant, have it bite the area, and cut off its head.

Only barley may be used. Iron would cause a bruise or inflammation.

This remedy helps only for a small puncture. If it is big, the sealing will peel off.

(Rabah bar Rav Huna): One who urinates through two openings is forbidden.

(Rava): The Halachah does not follow him, nor (the following law of) his father.

(Rav Huna): Women who rub their genitals together are disqualified from Kehunah.

(Rava): Even R. Elazar, who says that Bi'as Zenus makes a woman a Zonah, says so only about Bi'ah with a man. Two women together is mere lewdness.

(Mishnah): A Petzu'a Daka or Krus Shofchah is permitted to a convert or freed slave; he is only forbidden to Kehal (Yisraelim) - "He will not enter Kehal Hash-m".

(Gemara) Question: May a Petzu'a Daka Kohen marry a convert or freed slave?

If he retains his Kedushah, he is forbidden. If he lost his Kedushah, he is permitted.

Answer (Rav Sheshes - Beraisa): A Petzu'a Daka Yisrael may marry a Nesinah (a convert from the seven Kena'ani nations).

If he retains his Kedushah, he would transgress "Do not intermarry with them"!

Objection (Rava): That Isur does not depend on Kedushah. It is because their children might serve idolatry!

The Isur is only while they are Nochrim. After conversion the Torah permits them, but Chachamim decreed against them;

Chachamim forbade only people who can have children.

Objection: A Mamzer can have children. Why is he permitted?

(Mishnah): Mamzerim and Nesinim may intermarry.

Retraction (of statement 2): Rather, Chachamim forbade only people of Kosher lineage.

Retraction (of objection (d) - Rava): "Do not intermarry with them" applies only after conversion. Before this, marriage does not take effect!

Question (Rav Yosef): "Shlomo married the daughter of Paro, King of Mitzrayim".

Answer #1: He converted her beforehand.

Question: We did not accept converts in the days of David and Shlomo!

Answer: This is because we suspected that they convert only for wealth. Paro's daughter was already wealthy!

Question: If she converted, she was a Mitzris Rishonah, and was forbidden! (The Torah forbids the first two generations of Mitzri converts.)

Suggestion: Perhaps the Mitzriyim perished, and other nations settled in Mitzrayim (and Paro's daughter was from them).

Rejection (Beraisa - R. Yehudah): Minyamin my colleague was a Mitzri Rishon. He married a Mitzris Rishonah, and planned to marry his son to a Mitzris Sheniyah (second generation Mitzris), so his grandchildren would be permitted.

Answer #2 (to Question (f) - Rav Papa): Shlomo did not marry Bas Paro - "The forbidden nations ... Shlomo clung to love (not marriage)".

Question: It says "Va'Yischaten" (he married her)!

Answer: Because he loved her excessively, the verse calls it marriage.

Question (Ravina - Mishnah): A Petzu'a Daka or Krus Shofchah is permitted to a convert or freed slave.

Inference: He is forbidden to a Nesinah (this contradicts the Beraisa (c))!

Counter-question (Rav Ashi - Seifa of Mishnah): He is only forbidden to Kehal (Hash-m).

This implies that he may marry a Nesinah!

Answer to both questions: The implications in the Mishnah contradict each other, so we cannot infer the law of a Nesinah. (Therefore, we can say that the Mishnah agrees with the Beraisa.)

(Mishnah): (Male) Amonim and Mo'avim are forever forbidden. Females are permitted immediately;

Mitzriyim and Edomim are forbidden until three generations, males and females;

R. Shimon permits females immediately.

R. Shimon: A Kal va'Chomer permits them. When males are forbidden forever (Amon and Mo'av), the females are permitted immediately. When the males are forbidden only for two generations, all the more so females are permitted immediately!

Chachamim: If you have a tradition for your law, we accept it. If not, we can challenge your Kal va'Chomer.

R. Shimon: I have a tradition.

(Gemara) Question: What is the source that females of Amon and Mo'av are permitted?

Answer (R. Yochanan): "Sha'ul asked 'Who is this youth (David)?'... Avner said 'I do not know.'"

Objection: Sha'ul certainly knew who David was - "He loved him greatly, he (David) carried his (Sha'ul's) Kelim"!

Answer: Sha'ul asked about David's father.

Objection: Sha'ul certainly knew who David's father was - "The man was a famous sage ..."

(Rav): This is Yishai, who was appointed over 600,000!

Answer: Rather, Sha'ul asked if David descends from Peretz or from Zerach;

If he comes from Peretz he will be king, since a king is Poretz (breaks fences) to make a path for himself;

If he comes from Zerach, he is merely important.

Question: Why did Sha'ul inquire about David?

Answer: "Sha'ul clothed David in his (Sha'ul's) garments, like his measure". (This suggested that David would be king, for) Sha'ul was "From his shoulder and above taller than the whole nation"!

Doeg ha'Edomi: Before asking if he is fit for kingship, ask if he may marry into Yisrael!

Avner: Why shouldn't he be?

Do'eg: He descends from Rus the Mo'avis.

Avner: We learned that an Amoni and a Mo'avi are forbidden, but an Amonis and a Mo'avis are not!

Question (Doeg): If so, you should say that a Mamzer is forbidden, but not a Mamzeres!

Answer (Avner): "MaMZeR" alludes to MuM ZaR (a foreign blemish), which applies equally to women.

Question (Doeg): If so, you should say that a Mitzri is forbidden, not a Mitzris!

Answer (Avner): The Isur of Mo'av is different, since the Torah specified the reason - "Because they did not go out to greet you with bread and water";

This reason does not apply to women, for it is normal for men to go out to greet, but not for women.

Objection (Doeg): The men should have gone out to greet the men, and the women to greet the women!

Avner was silent.

Question: "The king said 'ask whose son is this EleM (youth)'". Before, he is called a "Na'ar"!

Answer: Sha'ul hinted to Avner 'this law NisALMah (is hidden) from you. Go ask in the Beis Medrash.'

He asked. They said that Amoni is forbidden, but not Amonis, and similarly Mo'avi but not Mo'avis.
