או צבור וצבור אבל יחיד לגבי צבור כמאן דלא צלי דמי קמשמע לן ואי אשמעינן הכא משום דלא אתחיל בה אבל התם דאתחיל בה אימא לא צריכא
or a case where he prayed as part of a congregation and began to repeat it as part of a congregation; however, in a case where he initially prayed by himself and subsequently joined the congregation at the venue where it was praying, we might have said that an individual vis-à-vis the congregation is considered as one who has not prayed. Therefore, he taught us that in this case, too, one may not repeat the prayer. And, on the other hand, if he had taught us here only with regard to one who entered a synagogue, we would have thought that the reason he may not pray again is because he did not yet begin to recite the prayer, but there, in the case where he already began to recite the prayer, say that this is not the case and he may continue to repeat the prayer. Therefore, both statements are necessary.
אמר רב הונא הנכנס לבית הכנסת ומצא צבור שמתפללין אם יכול להתחיל ולגמור עד שלא יגיע שליח צבור למודים יתפלל ואם לאו אל יתפלל רבי יהושע בן לוי אמר אם יכול להתחיל ולגמור עד שלא יגיע שליח צבור לקדושה יתפלל ואם לאו אל יתפלל
Rav Huna said: One who did not yet pray and enters a synagogue and found that the congregation is in the midst of reciting the Amida prayer, if he is able to begin and complete his own prayer before the prayer leader reaches the blessing of thanksgiving [modim], he should begin to pray, and, if not, he should not begin to pray. Rabbi Yehoshua ben Levi said: If he is able to begin and complete his prayer before the prayer leader reaches sanctification [kedusha], then he should begin to pray. If not, then he should not begin to pray.
במאי קא מפלגי מר סבר יחיד אומר קדושה ומר סבר אין יחיד אומר קדושה
The Gemara clarifies: With regard to what do they disagree? The basis for their dispute is that one Sage, Rav Huna, holds: An individual is permitted to recite kedusha on his own, so he need not insist on reciting it along with the prayer leader; and the other Sage, Rabbi Yehoshua ben Levi, holds that an individual may not recite kedusha alone, and, therefore he is required to complete his prayer before the communal prayer leader reaches kedusha.
וכן אמר רב אדא בר אהבה מנין שאין היחיד אומר קדושה שנאמר ונקדשתי בתוך בני ישראל כל דבר שבקדושה לא יהא פחות מעשרה
Similarly, Rav Adda bar Ahava stated, in accordance with the second opinion: From where is it derived that an individual may not recite kedusha alone? As it is stated: “And I shall be hallowed among the children of Israel” (Leviticus 22:32), any expression of sanctity may not be recited in a quorum of fewer than ten men.
מאי משמע דתני רבנאי אחוה דרבי חייא בר אבא אתיא תוך תוך כתיב הכא ונקדשתי בתוך בני ישראל וכתיב התם הבדלו מתוך העדה הזאת מה להלן עשרה אף כאן עשרה
The Gemara asks: How is this inferred from that verse? The Gemara responds: This must be understood in light of a baraita, which was taught by Rabbenai, the brother of Rabbi Ḥiyya bar Abba: It is inferred by means of a verbal analogy [gezera shava] between the words among, among. Here it is written: “And I shall be hallowed among the children of Israel,” and there, regarding Korah’s congregation, it is written “Separate yourselves from among this congregation” (Numbers 16:21). Just as there among connotes ten, so too here, among connotes ten. The connotation of ten associated with the word among written in the portion of Korah is, in turn, derived by means of another verbal analogy between the word congregation written there and the word congregation written in reference to the ten spies who slandered Eretz Yisrael: “How long shall I bear with this evil congregation?” (Numbers 14:27). Consequently, among the congregation there must be at least ten.
ודכולי עלמא מיהת מפסק לא פסיק
And, in any case, everyone agrees that one may not interrupt his prayer in order to respond to kedusha.
איבעיא להו מהו להפסיק ליהא שמו הגדול מבורך כי אתא רב דימי אמר רבי יהודה ורבי שמעון תלמידי דרבי יוחנן אמרי לכל אין מפסיקין חוץ מן יהא שמו הגדול מבורך שאפילו עוסק במעשה מרכבה פוסק ולית הלכתא כותיה:
However, a dilemma was raised before the Sages of the yeshiva: What is the ruling? Is one permitted to interrupt his prayer in order to recite: “May His great name be blessed” in kaddish? When Rav Dimi came from Eretz Yisrael to Babylonia, he said: Rabbi Yehuda and Rabbi Shimon, disciples of Rabbi Yoḥanan, said: One may not interrupt his prayer for anything, except for: “May His great name be blessed,” as even if one was engaged in the exalted study of the Act of the Divine Chariot [Ma’aseh Merkava] (see Ezekiel 1) he stops to recite it. However, the Gemara concludes: The halakha is not in accordance with his opinion.
רבי יהודה אומר מברך לפניהם ולאחריהם: למימרא דקסבר רבי יהודה בעל קרי מותר בדברי תורה והאמר רבי יהושע בן לוי מנין לבעל קרי שאסור בדברי תורה שנאמר והודעתם לבניך ולבני בניך וסמיך ליה יום אשר עמדת וגו׳ מה להלן בעלי קריין אסורין אף כאן בעלי קריין אסורין
We learned in the mishna that Rabbi Yehuda says with regard to one who experiences a seminal emission; he recites a blessing beforehand and afterward in both the case of Shema and in the case of food. The Gemara asks: Is that to say that Rabbi Yehuda holds that one who experienced a seminal emission is permitted to engage in matters of Torah? Didn’t Rabbi Yehoshua ben Levi say: From where in the Torah is it derived that one who experiences a seminal emission is prohibited from engaging in matters of Torah? As it is stated: “Just take heed and guard your soul diligently lest you forget the things your eyes have seen, and lest they depart from your heart, for all the days of your life, and you shall impart them to your children and your children’s children” (Deuteronomy 4:9), from which we derive, among other things, the obligation to study Torah. And, juxtaposed to it, is the verse: “The day that you stood before the Lord your God at Horeb” (Deuteronomy 4:10). This juxtaposition teaches us that just as below, at the revelation at Mount Sinai, those who experienced a seminal emission were prohibited and were commanded to refrain from relations with their wives and immerse themselves, so too here, throughout the generations, those who experience a seminal emission are prohibited from engaging in Torah study.
וכי תימא רבי יהודה לא דריש סמוכים והאמר רב יוסף אפילו מאן דלא דריש סמוכים בכל התורה במשנה תורה דריש דהא רבי יהודה לא דריש סמוכין בכל התורה כולה ובמשנה תורה דריש
And if you say that Rabbi Yehuda does not derive homiletic interpretations from juxtaposed verses, didn’t Rav Yosef already say: Even one who does not derive homiletic interpretations from juxtaposed verses throughout the entire Torah, nevertheless, derives them in Deuteronomy [Mishne Torah], as Rabbi Yehuda does not derive homiletic interpretations from juxtaposed verses throughout the entire Torah and he does derive them in Mishne Torah.
ובכל התורה כולה מנא לן דלא דריש דתניא בן עזאי אומר נאמר מכשפה לא תחיה ונאמר כל שוכב עם בהמה מות יומת סמכו ענין לו לומר מה שוכב עם בהמה בסקילה אף מכשפה נמי בסקילה
And from where do we derive that Rabbi Yehuda does not derive homiletic interpretations from juxtaposed verses throughout the entire Torah? As it was taught in a baraita with regard to the punishment of a sorceress, ben Azzai says: It is stated: “You shall not allow a sorceress to live” (Exodus 22:17), although the manner of her execution is not specified, and it is stated: “Whoever lies with a beast shall surely be put to death” (Exodus 22:18). The fact that the Torah juxtaposed this matter to that was to say: Just as one who lies with a beast is executed by stoning (see Leviticus 20), so too a sorceress is executed by stoning.
אמר ליה רבי יהודה וכי מפני שסמכו ענין לו נוציא לזה לסקילה אלא אוב וידעוני בכלל כל המכשפים היו ולמה יצאו להקיש להן ולומר לך מה אוב וידעוני בסקילה אף מכשפה בסקילה
With regard to this proof Rabbi Yehuda said to him: And does the fact that the Torah juxtaposed this matter to that warrant taking this person out to be stoned? Should he be sentenced to the most severe of the death penalties on that basis Rather, the source is: Mediums and wizards were included among all sorcerers. And why were they singled out from the rest, in the verse: “And a man or a woman who is a medium or a wizard shall surely be put to death; they shall stone them with stones, their blood is upon them” (Leviticus 20:27)? In order to draw an analogy to them and say to you: Just as a medium and a wizard are executed by stoning, so too is a sorceress executed by stoning.
ובמשנה תורה מנא לן דדריש דתניא רבי אליעזר אומר נושא אדם אנוסת אביו ומפותת אביו אנוסת בנו ומפותת בנו
And from where do we derive that Rabbi Yehuda derives homiletic interpretations from juxtaposed verses in Mishne Torah? As it was taught in another baraita: Rabbi Eliezer said that a man may wed a woman raped by his father and one seduced by his father; a woman raped by his son and one seduced by his son. Though one is prohibited by Torah law from marrying the wife of his father or the wife of his son, this prohibition does not apply to a woman raped or seduced by them.
רבי יהודה אוסר באנוסת אביו ובמפותת אביו ואמר רב גידל אמר רב מאי טעמא דרבי יהודה דכתיב לא יקח איש את אשת אביו ולא יגלה (את) כנף אביו כנף שראה אביו לא יגלה
And Rabbi Yehuda prohibits him from marrying a woman raped by his father and a woman seduced by his father. And Rav Giddel said that Rav said: What is the reason for Rabbi Yehuda’s opinion? As it is written: “A man shall not take his father’s wife, and shall not uncover his father’s skirt” (Deuteronomy 23:1). The last expression, “and shall not uncover his father’s skirt,” implies that: A skirt that has been seen by his father, i.e., any woman who has had sexual relations with his father, may not be uncovered by his son, i.e., his son may not marry her.
וממאי דבאנוסת אביו כתיב דסמיך ליה ונתן האיש השוכב עמה וגו׳
And from where do we know that the verse is written with regard to a woman raped by his father? As the previous section, juxtaposed to it, deals with the laws of rape: “And the man who lay with her must give her father fifty shekels…because he has violated her” (Deuteronomy 22:29).
אמרי אין במשנה תורה דריש והני סמוכין מבעי ליה לאידך דרבי יהושע בן לוי דאמר רבי יהושע בן לוי כל המלמד לבנו תורה מעלה עליו הכתוב כאלו קבלה מהר חורב שנאמר והודעתם לבניך ולבני בניך וכתיב בתריה יום אשר עמדת לפני ה׳ אלהיך בחורב
At any rate, we see that in Deuteronomy, Rabbi Yehuda derives homiletic interpretations from juxtaposed verses. Why does he fail to derive that one who experiences a seminal emission is prohibited from engaging in matters of Torah from the juxtaposition of the verses? They replied: Indeed, in Mishne Torah Rabbi Yehuda does derive homiletic interpretations from the juxtaposition of verses, but he requires these juxtaposed verses in order to derive another statement of Rabbi Yehoshua ben Levi, as Rabbi Yehoshua ben Levi said: One who teaches his son Torah, the verse ascribes to him credit as if he received the Torah from Mount Horeb. As it is stated: “And you shall impart them to your children and your children’s children” (Deuteronomy 4:9) after which it is written: “The day that you stood before the Lord your God at Horeb.” Therefore, Rabbi Yehuda cannot derive from that same juxtaposition a prohibition banning one who experienced a seminal emission from engaging in matters of Torah.
תנן זב שראה קרי ונדה שפלטה שכבת זרע המשמשת וראתה דם צריכין טבילה ורבי יהודה פוטר
We learned in a mishna that a zav who experienced a seminal emission, and a menstruating woman who discharged semen, and a woman who engaged in intercourse with her husband and she saw menstrual blood, all of whom are ritually impure for at least seven days due to the severity of their impurity, nevertheless require ritual immersion in order to purify themselves from the impurity of the seminal emission before they may engage in matters of Torah. And Rabbi Yehuda exempts them from immersion.
עד כאן לא פטר רבי יהודה אלא בזב שראה קרי דמעיקרא לאו בר טבילה הוא אבל בעל קרי גרידא מחייב
However, Rabbi Yehuda only exempted from immersion in the case of a zav who experienced a seminal emission, who was unfit to immerse himself from the outset, as even after immersion he would remain impure with the seven-day impurity of the zav. But, in the case of one who experienced a seminal emission alone, with no concurrent impurity, even Rabbi Yehuda requires immersion before he may engage in Torah matters.
וכי תימא הוא הדין דאפילו בעל קרי גרידא נמי פטר רבי יהודה והאי דקא מפלגי בזב שראה קרי להודיעך כחן דרבנן אימא סיפא המשמשת וראתה דם צריכה טבילה
And if you say: The same is true even in the case of one who experienced a seminal emission alone, that Rabbi Yehuda also exempts him from immersion, and the fact that they disagree in the case of a zav who experienced a seminal emission and not in the case of a person who experienced a seminal emission alone is in order to convey the far-reaching nature of the opinion of the Rabbis, who require immersion even in this case. If so, say the last case of that same mishna: A woman who was engaged in intercourse and she saw menstrual blood requires immersion.
למאן קתני לה אילימא לרבנן פשיטא השתא ומה זב שראה קרי דמעיקרא לאו בר טבילה הוא מחייבי רבנן המשמשת וראתה דם דמעיקרא בת טבילה היא לא כל שכן אלא לאו רבי יהודה היא ודוקא קתני לה
The Gemara seeks to clarify: In accordance with whose opinion was this case in the mishna taught? If you say that it is in accordance with the opinion of the Rabbis, that is obvious; if in the case of a zav who experienced a seminal emission who was unfit to immerse himself from the outset, when he experienced the seminal emission, the Rabbis nevertheless require immersion, all the more so wouldn’t they require immersion for a woman who engaged in intercourse and only then saw blood, who was fit to immerse herself from the outset, when she came into contact with the seminal emission of her husband? Rather, isn’t this Rabbi Yehuda’s opinion, and this case was taught specifically in order to teach
