Eruvin 30
This week’s learning is sponsored by Terri Krivosha in honor of Judge Norman Krivosha. My father, Judge Norman Krivosha, has encouraged my sister and me, since we were young girls growing up in the sixties, that girls could do anything to which we set our minds. Who would have ever thought that could mean reading the entire talmud from beginning to end? He has been and still is my mentor, father, friend and advisor and I love him very much.
Today’s daf is sponsored by Mindy and Eric Hecht and family in honor of their niece Talya Agus who is drafting today. We are so proud of you and wish you much success over the next two years of your service to Medinat Yisrael.
Do we determine the amount of food one needs to use for the eruv based on the average person or based on the specific person making the eruv. Is it objective or subjective? If one vows not to eat a certain food, can one use it for the eruv? Does it depend on the wording used for the vow – whether or not it included not benefiting from the bread? Beit Shamai and Beit Hillel disagree about whether or not an Israelite can use an eruv with truma or a nazir with wine. What does Sumchus hold that an Israelite cannot use truma for an eruv but a nazir can use wine? Why can a priest put his eruv in a beit hapras where there may be bones from a dead body? What it the root of the debate in the mishna regarding a priest putting an eruv in a cemetery?

אבל בגדי עשירים לעניים לא
But the clothing of the wealthy does not need to be three by three handbreadths in order to become ritually impure for the poor because even smaller pieces of cloth are significant for the poor. Therefore, the law with regard to the poor is not determined by the customary practice of the rich. So too, the law of eiruv pertaining to the rest of the world should not be determined by the customary practice of the Persians to eat roasted meat as a food in itself.
וכי תימא הכא לחומרא והכא לחומרא והתניא רבי שמעון בן אלעזר אומר מערבין לחולה ולזקן כדי מזונו ולרעבתן בסעודה בינונית של כל אדם קשיא
And if you say: Both here the ruling is stringent, and there the ruling is stringent, i.e., with regard to ritual impurity the halakha is stringent with respect to the poor and declares scraps of cloth that are only three by three fingerbreadths impure, but with regard to eiruv the halakha requires enough roasted meat to suffice for two meals as a food in its own right, in accordance with the practice of the Persians, then there is a difficulty: Wasn’t it taught in a baraita that Rabbi Shimon ben Elazar says: One may establish an eiruv for an ill or elderly person with an amount of food that is enough for him for two meals, and if he eats less than the average person due to his sickness or age, a smaller amount of food is required in order to establish an eiruv on his behalf; however, for a glutton, we do not require food in an amount that would satisfy him but merely enough food for two meals measured according to an average meal for the typical person? This indicates that the halakha with respect to an eiruv is lenient and not stringent. The Gemara concludes: Indeed, this is difficult.
ומי אמר רבי שמעון בן אלעזר הכי והתניא רבי שמעון בן אלעזר אומר עוג מלך הבשן פיתחו כמלואו
The Gemara raises a difficulty with the aforementioned baraita: Did Rabbi Shimon ben Elazar really say this? Wasn’t it taught in another baraita pertaining to the laws of ritual impurity that Rabbi Shimon ben Elazar says: Og, king of the Bashan, or any similar giant, requires an opening as big as his full size? If a person dies in a house and it is not clear how his corpse will be removed, all of the openings in the house are considered ritually impure, as the corpse might be carried out through any one of them. If the corpse can fit through some of the openings but not through others, only the larger openings are ritually impure. Rabbi Shimon ben Elazar says that in the case of a giant the size of Og, king of the Bashan, one opening can only prevent the others from contracting impurity if it is large enough for Og’s corpse to fit through. This indicates that the law is determined by the measure of each particular person and not by some general measure.
ואביי התם היכי ליעביד הדומי נהדמיה [ונפקיה]
The Gemara asks: And what does Abaye say? How does he reconcile his position with regard to an eiruv, which maintains that we follow the customary practice of most of the world and not that of particular locales, with Rabbi Shimon ben Elazar’s ruling with regard to the corpse of a giant? The Gemara answers: There, in the case of a giant, what should we do? Should we cut the corpse into pieces and carry it out? We have no choice but to carry it out through an opening large enough for the corpse to pass through. However, in the case of the food for the two meals of an eiruv, there is no such logistical constraint, and the law should be determined in accordance with the usual practice.
איבעיא להו פליגי רבנן עליה דרבי שמעון בן אלעזר או לא תא שמע דאמר רבה בר בר חנה אמר רבי יוחנן עוג מלך הבשן פיתחו בארבעה
A dilemma was raised before the Sages: Do the Rabbis disagree with Rabbi Shimon ben Elazar, or not? Come and hear a proof from that which Rabba bar bar Ḥana said that Rabbi Yoḥanan said: Og, king of the Bashan, requires an opening of four handbreadths in order to save the other openings in the house from becoming ritually impure. This indicates that the Rabbis disagree with Rabbi Shimon ben Elazar.
התם דאיכא פתחים קטנים טובא ואיכא חד דהוי ארבעה דודאי כי קא מרוח בההוא קא מרוח
The Gemara rejects this proof: There, we are dealing with a case where there are many small openings, and there is only one that is four handbreadths wide. Therefore, it may be assumed with certainty that when one widens one of the openings in order to remove the corpse from the house, he will widen that opening. Consequently, that opening is ritually impure while the others are not. However, if all the openings in the house are equal in size, they are all ritually impure, as we cannot know through which opening the corpse will be carried out.
אמר רב חייא בר רב אשי אמר רב מערבין בבשר חי אמר רב שימי בר חייא מערבין בביצים חיות וכמה אמר רב נחמן בר יצחק אחת סיני אמר שתים:
Returning to the laws of eiruv, Rav Ḥiyya bar Rav Ashi said that Rav said: One may establish an eiruv with raw meat because it can be eaten when necessary, even though it is not ordinarily regarded as food. Rav Shimi bar Ḥiyya said: One may also establish an eiruv with raw eggs. The Gemara asks: How many eggs are required for an eiruv? Rav Naḥman bar Yitzḥak said: One. Sinai, a nickname of Rav Yosef, said: Two.
הנודר מן המזון מותר במים כו׳: מלח ומים הוא דלא איקרי מזון הא כל מילי איקרי מזון לימא תיהוי תיובתא דרב ושמואל דרב ושמואל דאמרי תרוייהו אין מברכין בורא מיני מזונות אלא על חמשת המינין בלבד
We learned in the mishna: One who vows that nourishment is prohibited to him is permitted to eat water and salt. The Gemara infers from this: It is only salt and water that are not considered nourishment, but all other food items are considered nourishment. Let us say that this is a refutation of the position of Rav and Shmuel. As it was Rav and Shmuel who both said: One only recites the blessing: Who creates the various kinds of nourishment, over the five species of grain alone, but not over other types of food.
ולא אותביניה חדא זימנא לימא תיהוי תיובתייהו נמי מהא
The Gemara asks a question: Did we not already refute their position on one occasion from a different source? The Gemara answers: Indeed, we already refuted their view, but let us say that there is a refutation of their position from here as well.
אמר רב הונא באומר כל הזן עלי מים ומלח הוא דלא זייני הא כל מילי זייני
Rav Huna said: We can resolve the difficulty from the mishna by saying that it is referring to someone who vows and says: Anything that nourishes is prohibited to me. In that case, it is water and salt that are permitted to him, as they do not nourish, but all other food items are prohibited, as they do nourish. This inclusive formulation includes anything that provides even a small degree of nourishment; but the particular term mazon, nourishment or sustenance, used in the blessing over food, is reserved only for the five species of grain.
והאמר רבה בר בר חנה כי הוה אזילנא בתריה דרבי יוחנן למיכל פירי דגינוסר כי הוינן בי מאה הוה מנקטינן לכל חד וחד עשרה עשרה כי הוינן בי עשרה הוה מנקטינן לכל חד וחד מאה מאה וכל מאה מינייהו (לא) הוי מחזיק להו צנא בת תלתא סאוי והוה אכיל להו לכולהון ואמר שבועתא דלא טעים לי זיונא אימא מזונא
The Gemara asks: Didn’t Rabba bar bar Ḥana say: When we were following Rabbi Yoḥanan to eat of the fruits of Genosar, very sweet fruits that grow in the region of the Sea of Galilee, when we were a group of a hundred people, each and every person would take ten fruits; and when we were a group of ten, each and every person would take a hundred fruits for him. And each hundred of these fruits could not fit into a three-se’a basket. And Rabbi Yoḥanan would eat them all and then say: I swear that I have not yet tasted something that nourishes. Didn’t we say that only water and salt are excluded from the category of things that nourish? The Gemara corrects the rendition of the story: Say that he said as follows: I have not tasted sustaining food, but fruit is certainly considered something that nourishes.
אמר רב הונא אמר רב שבועה שלא אוכל ככר זו מערבין לו בה ככר זו עלי אין מערבין לו בה
Rav Huna said that Rav said: If one said: I swear that I shall not eat this loaf, one may nonetheless establish an eiruv for him with it because the food used for an eiruv does not have to be edible for the particular individual the eiruv services. However, if one said: This loaf shall be forbidden to me, one may not establish an eiruv for him with it, as this formulation indicates that he is prohibiting himself to use or benefit from the loaf in any manner.
מיתיבי הנודר מן הככר מערבין לו בה מאי לאו דאמר עלי לא דאמר זו
The Gemara raises an objection based upon the following baraita: With regard to one who vows not to benefit from a loaf, one may nonetheless establish an eiruv for him with it. What, is it not referring to one who said: This loaf shall be forbidden to me? The Gemara answers: No, the baraita is only is referring to a case where he said: I swear that I shall not eat this loaf.
הכי נמי מסתברא דקתני סיפא אימתי בזמן שאמר שבועה שלא אטעמנה
The Gemara comments: So too, it is reasonable to understand the baraita in this fashion, as it was taught in the latter clause: When do we apply this halakha? Only when one said: I swear that I shall not taste it.
אבל אמר עלי מאי הכי נמי דאין מערבין לו בה אי הכי אדתני ככר זו הקדש אין מערבין לו בה לפי שאין מערבין בהקדשות ליפלוג וליתני בדידה במה דברים אמורים דאמר זו אבל אמר עלי אין מערבין לו בה
The Gemara asks: But if he said: This loaf shall be forbidden to me, what is the halakha? So too, one may not establish an eiruv for him with it. But if so, there is a difficulty. Instead of teaching in the continuation of the baraita that if one said: This loaf is consecrated property, one may not establish an eiruv for him with it, as one may not establish an eiruv with consecrated objects, let him make an internal distinction in the case of a non-sacred loaf itself and state: In what case is this statement said? Only where one said: I swear that I shall not eat this loaf. But if one said: This loaf shall be forbidden to me, one may not establish an eiruv for him with it. This indicates that Rav Huna’s understanding of the baraita is incorrect.
אמר לך רב הונא אלא מאי כל היכא דאמר עלי מערבין קשיא רישא
Rav Huna could have said to you: Rather, what would you say, that wherever one said: This loaf shall be forbidden to me, one may establish an eiruv for him with it? If so, there is a difficulty from the first clause of the baraita, which states: When do we say this? Only when one said: I swear that I shall not taste it. That indicates that if one said: This loaf shall be forbidden to me, one may not establish an eiruv for him with it.
חסורי מיחסרא והכי קתני הנודר מן הככר מערבין לו בה ואפילו אמר עלי נעשה כאומר שבועה שלא אטעמנה
The Gemara answers that the baraita is incomplete, and it teaches the following: With regard to one who vows not to benefit from a loaf, one may nonetheless establish an eiruv for him with it. And even if one said: This loaf shall be forbidden to me, it is as though he said: I swear that I shall not taste it. Therefore, the loaf itself is only forbidden to him as food, but he can use it for the purpose of an eiruv.
מכל מקום קשיא לרב הונא הוא דאמר כרבי אליעזר דתניא רבי אליעזר אומר שבועה שלא אוכל ככר זו מערבין לו בה ככר זו עלי אין מערבין לו בה
The Gemara comments: Nevertheless, the difficulty remains according to the opinion of Rav Huna. The Gemara answers: He stated his view in accordance with the opinion of Rabbi Eliezer; as it was taught in a baraita that Rabbi Eliezer says: If one said: I swear that I shall not eat this loaf, one may establish an eiruv for him with it; but if he said: This loaf shall be forbidden to me, one may not establish an eiruv for him with it.
ומי אמר רבי אליעזר הכי והתניא זה הכלל אדם אוסר עצמו באוכל מערבין לו בה אוכל הנאסר לו לאדם אין מערבין לו בה רבי אליעזר אומר ככר זו עלי מערבין לו בה ככר זו הקדש אין מערבין לו בה לפי שאין מערבין לו בהקדשות
The Gemara asks: Did Rabbi Eliezer really say this? Wasn’t it taught in a baraita: This is the principle: With regard to a person who prohibits himself from eating a particular food, e.g., if one said: I swear that I shall not eat this loaf, one may establish an eiruv for him with that loaf. However, if the food was prohibited to a person, e.g., if he said: This loaf shall be forbidden to me, one may not establish an eiruv for him with it. Rabbi Eliezer says: If he said: This loaf shall be forbidden to me, one may establish an eiruv for him with it. However, if he said: This loaf is consecrated property, one may not establish an eiruv for him with it, as one may not establish an eiruv for him with consecrated objects. Therefore, Rabbi Eliezer does not distinguish between the two differently worded types of vows, but between a vow and consecration.
תרי תנאי ואליבא דרבי אליעזר:
The Gemara answers: It must be explained that these are two tanna’im who both held according to Rabbi Eliezer. Two later tanna’im disagreed with each other in reporting Rabbi Eliezer’s opinion.
מערבין לנזיר ביין כו׳: מתניתין דלא כבית שמאי דתניא בית שמאי אומרים אין מערבין לנזיר ביין ולישראל בתרומה בית הלל אומרים מערבין לנזיר ביין ולישראל בתרומה אמרו להן בית הלל לבית שמאי אי אתם מודים
We learned in the mishna: One may establish an eiruv for a nazirite with wine and for an Israelite with teruma, even though they themselves may not partake of these foods. The Gemara comments: The mishna was not taught in accordance with the opinion of Beit Shammai, as it was taught in a baraita that Beit Shammai say: One may not establish an eiruv for a nazirite with wine and for an Israelite with teruma. Beit Hillel disagree and say: One may establish an eiruv for a nazirite with wine and for an Israelite with teruma. Beit Hillel said to Beit Shammai: Do you not concede
שמערבין לגדול ביום הכפורים
that one may establish an eiruv for an adult even on Yom Kippur, despite the fact that he may not eat on Yom Kippur? It must be because eating is permitted to a minor.
אמרו להן אבל אמרו להן כשם שמערבין לגדול ביום הכפורים כן מערבין לנזיר ביין ולישראל בתרומה
Beit Shammai said to them: Indeed [aval], it is so. Beit Hillel said to them: Just as one may establish an eiruv for an adult on Yom Kippur, so too, one may establish an eiruv for a nazirite with wine and for an Israelite with teruma.
ובית שמאי התם איכא סעודה הראויה מבעוד יום הכא ליכא סעודה הראויה מבעוד יום
And how do Beit Shammai explain the difference between these cases? The Gemara explains: There, with regard to Yom Kippur, there is at least a meal that was fit to be eaten by that person while it was still day, on the eve of Yom Kippur. Here, in the cases of wine for a nazirite and teruma for an Israelite, there is no meal that was fit to be eaten by them while it was still day, on Friday.
כמאן דלא כחנניה דתניא חנניה אומר כל עצמן של בית שמאי לא היו מודים בעירוב עד שיוציא מטתו וכל כלי תשמישיו לשם
The Gemara asks: In accordance with whose opinion was that entire baraita stated? It was not taught in accordance with the opinion of Ḥananya, as it was taught in another baraita that Ḥananya says: The whole view of Beit Shammai, i.e., their fundamental position, was that they did not concede to the very possibility of joining Shabbat borders [eiruv teḥumin] by simply placing food in a particular location. Rather, they hold that one’s Shabbat residence remains the same until he literally moves his residence, such as if he carries out his bed and his utensils to there, to a new location.
כמאן אזלא הא דתניא עירב בשחורים לא יצא בלבנים בלבנים לא יצא בשחורים כמאן אמר רב נחמן בר יצחק חנניה היא ואליבא דבית שמאי
The Gemara asks: In accordance with whose opinion is the ruling that was taught in the following baraita: If one established an eiruv in black clothing, and Shabbat commenced while he was still dressed those clothes, he may not go out in white clothing. If one established the eiruv while dressed in white, he may not go out in black. According to whose opinion is this halakha? Rav Naḥman bar Yitzḥak said: It is the opinion of Ḥananya, and it is in accordance with the opinion of Beit Shammai.
ולחנניה בשחורים הוא דלא יצא הא בלבנים יצא האמר עד שיוציא מטתו וכלי תשמישיו לשם הכי קאמר עירב בלבנים והוצרך לשחורים אף בלבנים לא יצא כמאן אמר רב נחמן בר יצחק חנניה היא ואליבא דבית שמאי:
The Gemara asks: And according to the opinion of Ḥananya, is it with black clothing that he may not go out, but in white clothing he may go out? Didn’t Ḥananya say that according to Beit Shammai an eiruv is not effective at all until one carries out his bed and his utensils to the place he wishes to establish as his residence? The Gemara answers: The wording of the baraita must be emended and this is what it said: If one established an eiruv while dressed in white clothing, and he needed black clothing but did not have it with him, he may not go out even in white clothing. In accordance with whose opinion was this baraita taught? Rav Naḥman bar Yitzḥak said: It is the opinion of Ḥananya, and it is in accordance with the opinion of Beit Shammai.
סומכוס אומר בחולין: ואילו לנזיר ביין לא פליג מאי טעמא אפשר דמתשיל אנזירותיה
We learned in the mishna: Summakhos disagrees and says: One may not establish an eiruv for an Israelite with teruma, but only with regular, non-sacred food items. The Gemara notes: But with regard to the mishna’s ruling that an eiruv may be established for a nazirite with wine, Summakhos does not appear to disagree. What is the reason for the distinction? The Gemara explains: A nazirite can ask a Sage to annul his vow and release him from his nazirite status, and then he himself will be able to drink the wine.
אי הכי תרומה נמי אפשר דמיתשיל עילויה אי מתשיל עלה הדרא לטיבלא
The Gemara asks: If so, in the case of teruma as well, one can ask a Sage to annul its status. Teruma is consecrated through a verbal declaration by the one separating it, and that declaration, like other consecrations and vows, can be nullified by a Sage. The Gemara answers: Such a course of action would not help. If one asks a Sage to annul his declaration that turned the produce into teruma, the produce will return to its status as tevel, produce from which the requisite dues and tithes were not separated, and he will still be prohibited to consume it.
וליפרוש עלה ממקום אחר לא נחשדו חבירים לתרום שלא מן המוקף
The Gemara asks: Let him separate teruma for that produce from produce located somewhere else and thus permit it to be eaten. The Gemara answers: Ḥaverim, members of a group dedicated to the precise observance of mitzvot, are not suspected of separating teruma from produce that is not situated near the produce it comes to exempt, as this is prohibited ab initio.
ולפרוש עלה מיניה וביה דלית בה שיעורא
The Gemara asks: Let him separate teruma from the produce used for the eiruv itself and consequently permit the rest of the produce to be eaten. The Gemara answers: We are dealing with a case where, after removing teruma, it would not contain the amount required for an eiruv, i.e., one would be left with less than the quantity of food sufficient for two meals.
ומאי פסקא אלא סומכוס סבר לה כרבנן דאמרי כל דבר שהוא משום שבות גזרו עליו בין השמשות
The Gemara asks: What makes it necessary to say that the mishna is referring to this very unique case? Rather, we must retract all that was stated above and say as follows: Summakhos agrees with the opinion of the Rabbis, who say: Anything that is prohibited on Shabbat due to a rabbinic decree [shevut], the Sages issued the decree to apply even during twilight. Even though this period is of questionable status with regard to whether it is day or night, the Shabbat restrictions instituted by the Sages apply then as they do on Shabbat itself. Consequently, since it is prohibited to separate teruma on Shabbat, it is prohibited during the twilight period as well. Therefore, during twilight, when the eiruv would go into effect, it is impossible to cause it to become permitted to an Israelite.
כמאן אזלא הא דתנן יש שאמרו הכל לפי מה שהוא אדם מלא קומצו מנחה ומלא חפניו קטרת והשותה מלא לוגמיו ביום הכפורים ובמזון שתי סעודות לעירוב כמאן אמר רבי זירא סומכוס היא דאמר מאי דחזי ליה בעינן
The Gemara now asks: In accordance with whose opinion is the ruling that we learned in the following mishna: There are halakhot with regard to which they stated that measures are all in accordance with the particular person involved, e.g., the handful of flour that a priest scoops out from a meal-offering, and the handfuls of incense the High Priest would offer on Yom Kippur, and one who drinks a cheekful on Yom Kippur, and with regard to the measure of two meals’ worth of nourishment for an eiruv. All these measures are determined by the particular individual involved. In accordance with whose opinion is this halakha? Rabbi Zeira said: It is in accordance with the opinion of Summakhos, who said: We require that which is fit for him, the particular individual, and we do not follow a standard measure.
לימא פליגא אדרבי שמעון בן אלעזר דתניא רבי שמעון בן אלעזר אומר מערבין לחולה ולזקן כדי מזונו ולרעבתן בסעודה בינונית של כל אדם
The Gemara suggests: Let us say that the aforementioned mishna disagrees with the opinion of Rabbi Shimon ben Elazar. As it was taught in a baraita: Rabbi Shimon ben Elazar says: One may establish an eiruv for an ill or elderly person with an amount of food that is enough for him for two meals; and if he eats less than the average amount due to his sickness or age, a smaller amount of food is sufficient. But for a glutton we do not require food in an amount that would satisfy him; we measure on the basis of an average meal for the typical person.
תרגומא אחולה וזקן אבל רעבתן בטלה דעתו אצל כל אדם:
The Gemara answers: When the mishna says that the measure of food for two meals is determined by the particular person involved, interpret that as referring to an ill or elderly person. But with regard to a glutton, we do not determine the measure of food by his standard for a different reason, namely because his opinion is rendered irrelevant by the opinions of all other people. Therefore, there is no reason to be stringent with him and determine the measure according to his particular needs.
ולכהן בבית הפרס: דאמר רב יהודה אמר שמואל מנפח אדם בית הפרס והולך רבי יהודה בר אמי משמיה דרב יהודה אמר בית הפרס שנידש טהור:
We learned in the mishna: One may establish an eiruv for a priest in a beit haperas, an area in which there is doubt concerning the location of a grave or a corpse. The Gemara explains that the reason for this is as Rav Yehuda said that Shmuel said: In a time of need a person may blow on the dust in a beit haperas before taking each step, so that if there is a bone beneath the dust he will expose it and avoid it, and he may thus walk across the area. Similarly, Rabbi Yehuda bar Ami said in the name of Rav Yehuda: A beit haperas that has been trodden underfoot, creating a path, is pure, as we assume that it no longer contains any bones as large as a kernel of barley. Both of these statements indicate that the ritual impurity of a beit haperas is a stringency decreed by the Sages. Therefore, since there is a way to avoid becoming ritually impure there, even a priest may place his eiruv in a beit haperas.
רבי יהודה אומר אף בית הקברות: תנא מפני שיכול לחוץ ולילך בשידה תיבה ומגדל קא סבר אהל זרוק שמיה אהל
We learned in the mishna that Rabbi Yehuda says: An eiruv may be established for a priest even in a cemetery, an area which the priest may not enter by Torah law. It was taught: This is permitted because the priest can interpose and walk between the graves inside a carriage, a crate, or a cupboard. These containers do not contract impurity because of their large size, and anything found inside of them remains pure. From here we see that he holds the following: A moving tent is called a tent, and therefore the carriage, box, or cupboard are also considered tents. They shield a person carried in them from the impurity imparted by the graves in a cemetery.
ובפלוגתא דהני תנאי דתניא הנכנס לארץ העמים בשידה תיבה ומגדל רבי מטמא רבי יוסי ברבי יהודה מטהר
The Gemara notes that this matter is the subject of a dispute between the following tanna’im, as it was taught in a baraita: With regard to one who enters the land of the nations, i.e., any territory outside Eretz Yisrael, not on foot, but in a carriage, a crate, or a cupboard, Rabbi Yehuda HaNasi renders him ritually impure. Rabbi Yosei, son of Rabbi Yehuda, renders him pure.
במאי קמיפלגי מר סבר אהל זרוק לאו שמיה אהל ומר סבר אהל זרוק שמיה אהל
The Gemara explains: With regard to what do they disagree? One Sage, Rabbi Yehuda HaNasi, holds that a moving tent is not called a tent. The principle is that only something fixed can shield against ritual impurity, but if one is situated inside a portable vessel, the vessel contracts impurity and he becomes impure along with it. And the other Sage, Rabbi Yosei, son of Rabbi Yehuda, holds that a moving tent is called a tent, and it shields the person inside from contracting ritual impurity.
והא דתניא רבי יהודה אומר
And with regard to that which was taught in a baraita: Rabbi Yehuda says:

אבל בגדי עשירים לעניים לא
But the clothing of the wealthy does not need to be three by three handbreadths in order to become ritually impure for the poor because even smaller pieces of cloth are significant for the poor. Therefore, the law with regard to the poor is not determined by the customary practice of the rich. So too, the law of eiruv pertaining to the rest of the world should not be determined by the customary practice of the Persians to eat roasted meat as a food in itself.
וכי תימא הכא לחומרא והכא לחומרא והתניא רבי שמעון בן אלעזר אומר מערבין לחולה ולזקן כדי מזונו ולרעבתן בסעודה בינונית של כל אדם קשיא
And if you say: Both here the ruling is stringent, and there the ruling is stringent, i.e., with regard to ritual impurity the halakha is stringent with respect to the poor and declares scraps of cloth that are only three by three fingerbreadths impure, but with regard to eiruv the halakha requires enough roasted meat to suffice for two meals as a food in its own right, in accordance with the practice of the Persians, then there is a difficulty: Wasn’t it taught in a baraita that Rabbi Shimon ben Elazar says: One may establish an eiruv for an ill or elderly person with an amount of food that is enough for him for two meals, and if he eats less than the average person due to his sickness or age, a smaller amount of food is required in order to establish an eiruv on his behalf; however, for a glutton, we do not require food in an amount that would satisfy him but merely enough food for two meals measured according to an average meal for the typical person? This indicates that the halakha with respect to an eiruv is lenient and not stringent. The Gemara concludes: Indeed, this is difficult.
ומי אמר רבי שמעון בן אלעזר הכי והתניא רבי שמעון בן אלעזר אומר עוג מלך הבשן פיתחו כמלואו
The Gemara raises a difficulty with the aforementioned baraita: Did Rabbi Shimon ben Elazar really say this? Wasn’t it taught in another baraita pertaining to the laws of ritual impurity that Rabbi Shimon ben Elazar says: Og, king of the Bashan, or any similar giant, requires an opening as big as his full size? If a person dies in a house and it is not clear how his corpse will be removed, all of the openings in the house are considered ritually impure, as the corpse might be carried out through any one of them. If the corpse can fit through some of the openings but not through others, only the larger openings are ritually impure. Rabbi Shimon ben Elazar says that in the case of a giant the size of Og, king of the Bashan, one opening can only prevent the others from contracting impurity if it is large enough for Og’s corpse to fit through. This indicates that the law is determined by the measure of each particular person and not by some general measure.
ואביי התם היכי ליעביד הדומי נהדמיה [ונפקיה]
The Gemara asks: And what does Abaye say? How does he reconcile his position with regard to an eiruv, which maintains that we follow the customary practice of most of the world and not that of particular locales, with Rabbi Shimon ben Elazar’s ruling with regard to the corpse of a giant? The Gemara answers: There, in the case of a giant, what should we do? Should we cut the corpse into pieces and carry it out? We have no choice but to carry it out through an opening large enough for the corpse to pass through. However, in the case of the food for the two meals of an eiruv, there is no such logistical constraint, and the law should be determined in accordance with the usual practice.
איבעיא להו פליגי רבנן עליה דרבי שמעון בן אלעזר או לא תא שמע דאמר רבה בר בר חנה אמר רבי יוחנן עוג מלך הבשן פיתחו בארבעה
A dilemma was raised before the Sages: Do the Rabbis disagree with Rabbi Shimon ben Elazar, or not? Come and hear a proof from that which Rabba bar bar Ḥana said that Rabbi Yoḥanan said: Og, king of the Bashan, requires an opening of four handbreadths in order to save the other openings in the house from becoming ritually impure. This indicates that the Rabbis disagree with Rabbi Shimon ben Elazar.
התם דאיכא פתחים קטנים טובא ואיכא חד דהוי ארבעה דודאי כי קא מרוח בההוא קא מרוח
The Gemara rejects this proof: There, we are dealing with a case where there are many small openings, and there is only one that is four handbreadths wide. Therefore, it may be assumed with certainty that when one widens one of the openings in order to remove the corpse from the house, he will widen that opening. Consequently, that opening is ritually impure while the others are not. However, if all the openings in the house are equal in size, they are all ritually impure, as we cannot know through which opening the corpse will be carried out.
אמר רב חייא בר רב אשי אמר רב מערבין בבשר חי אמר רב שימי בר חייא מערבין בביצים חיות וכמה אמר רב נחמן בר יצחק אחת סיני אמר שתים:
Returning to the laws of eiruv, Rav Ḥiyya bar Rav Ashi said that Rav said: One may establish an eiruv with raw meat because it can be eaten when necessary, even though it is not ordinarily regarded as food. Rav Shimi bar Ḥiyya said: One may also establish an eiruv with raw eggs. The Gemara asks: How many eggs are required for an eiruv? Rav Naḥman bar Yitzḥak said: One. Sinai, a nickname of Rav Yosef, said: Two.
הנודר מן המזון מותר במים כו׳: מלח ומים הוא דלא איקרי מזון הא כל מילי איקרי מזון לימא תיהוי תיובתא דרב ושמואל דרב ושמואל דאמרי תרוייהו אין מברכין בורא מיני מזונות אלא על חמשת המינין בלבד
We learned in the mishna: One who vows that nourishment is prohibited to him is permitted to eat water and salt. The Gemara infers from this: It is only salt and water that are not considered nourishment, but all other food items are considered nourishment. Let us say that this is a refutation of the position of Rav and Shmuel. As it was Rav and Shmuel who both said: One only recites the blessing: Who creates the various kinds of nourishment, over the five species of grain alone, but not over other types of food.
ולא אותביניה חדא זימנא לימא תיהוי תיובתייהו נמי מהא
The Gemara asks a question: Did we not already refute their position on one occasion from a different source? The Gemara answers: Indeed, we already refuted their view, but let us say that there is a refutation of their position from here as well.
אמר רב הונא באומר כל הזן עלי מים ומלח הוא דלא זייני הא כל מילי זייני
Rav Huna said: We can resolve the difficulty from the mishna by saying that it is referring to someone who vows and says: Anything that nourishes is prohibited to me. In that case, it is water and salt that are permitted to him, as they do not nourish, but all other food items are prohibited, as they do nourish. This inclusive formulation includes anything that provides even a small degree of nourishment; but the particular term mazon, nourishment or sustenance, used in the blessing over food, is reserved only for the five species of grain.
והאמר רבה בר בר חנה כי הוה אזילנא בתריה דרבי יוחנן למיכל פירי דגינוסר כי הוינן בי מאה הוה מנקטינן לכל חד וחד עשרה עשרה כי הוינן בי עשרה הוה מנקטינן לכל חד וחד מאה מאה וכל מאה מינייהו (לא) הוי מחזיק להו צנא בת תלתא סאוי והוה אכיל להו לכולהון ואמר שבועתא דלא טעים לי זיונא אימא מזונא
The Gemara asks: Didn’t Rabba bar bar Ḥana say: When we were following Rabbi Yoḥanan to eat of the fruits of Genosar, very sweet fruits that grow in the region of the Sea of Galilee, when we were a group of a hundred people, each and every person would take ten fruits; and when we were a group of ten, each and every person would take a hundred fruits for him. And each hundred of these fruits could not fit into a three-se’a basket. And Rabbi Yoḥanan would eat them all and then say: I swear that I have not yet tasted something that nourishes. Didn’t we say that only water and salt are excluded from the category of things that nourish? The Gemara corrects the rendition of the story: Say that he said as follows: I have not tasted sustaining food, but fruit is certainly considered something that nourishes.
אמר רב הונא אמר רב שבועה שלא אוכל ככר זו מערבין לו בה ככר זו עלי אין מערבין לו בה
Rav Huna said that Rav said: If one said: I swear that I shall not eat this loaf, one may nonetheless establish an eiruv for him with it because the food used for an eiruv does not have to be edible for the particular individual the eiruv services. However, if one said: This loaf shall be forbidden to me, one may not establish an eiruv for him with it, as this formulation indicates that he is prohibiting himself to use or benefit from the loaf in any manner.
מיתיבי הנודר מן הככר מערבין לו בה מאי לאו דאמר עלי לא דאמר זו
The Gemara raises an objection based upon the following baraita: With regard to one who vows not to benefit from a loaf, one may nonetheless establish an eiruv for him with it. What, is it not referring to one who said: This loaf shall be forbidden to me? The Gemara answers: No, the baraita is only is referring to a case where he said: I swear that I shall not eat this loaf.
הכי נמי מסתברא דקתני סיפא אימתי בזמן שאמר שבועה שלא אטעמנה
The Gemara comments: So too, it is reasonable to understand the baraita in this fashion, as it was taught in the latter clause: When do we apply this halakha? Only when one said: I swear that I shall not taste it.
אבל אמר עלי מאי הכי נמי דאין מערבין לו בה אי הכי אדתני ככר זו הקדש אין מערבין לו בה לפי שאין מערבין בהקדשות ליפלוג וליתני בדידה במה דברים אמורים דאמר זו אבל אמר עלי אין מערבין לו בה
The Gemara asks: But if he said: This loaf shall be forbidden to me, what is the halakha? So too, one may not establish an eiruv for him with it. But if so, there is a difficulty. Instead of teaching in the continuation of the baraita that if one said: This loaf is consecrated property, one may not establish an eiruv for him with it, as one may not establish an eiruv with consecrated objects, let him make an internal distinction in the case of a non-sacred loaf itself and state: In what case is this statement said? Only where one said: I swear that I shall not eat this loaf. But if one said: This loaf shall be forbidden to me, one may not establish an eiruv for him with it. This indicates that Rav Huna’s understanding of the baraita is incorrect.
אמר לך רב הונא אלא מאי כל היכא דאמר עלי מערבין קשיא רישא
Rav Huna could have said to you: Rather, what would you say, that wherever one said: This loaf shall be forbidden to me, one may establish an eiruv for him with it? If so, there is a difficulty from the first clause of the baraita, which states: When do we say this? Only when one said: I swear that I shall not taste it. That indicates that if one said: This loaf shall be forbidden to me, one may not establish an eiruv for him with it.
חסורי מיחסרא והכי קתני הנודר מן הככר מערבין לו בה ואפילו אמר עלי נעשה כאומר שבועה שלא אטעמנה
The Gemara answers that the baraita is incomplete, and it teaches the following: With regard to one who vows not to benefit from a loaf, one may nonetheless establish an eiruv for him with it. And even if one said: This loaf shall be forbidden to me, it is as though he said: I swear that I shall not taste it. Therefore, the loaf itself is only forbidden to him as food, but he can use it for the purpose of an eiruv.
מכל מקום קשיא לרב הונא הוא דאמר כרבי אליעזר דתניא רבי אליעזר אומר שבועה שלא אוכל ככר זו מערבין לו בה ככר זו עלי אין מערבין לו בה
The Gemara comments: Nevertheless, the difficulty remains according to the opinion of Rav Huna. The Gemara answers: He stated his view in accordance with the opinion of Rabbi Eliezer; as it was taught in a baraita that Rabbi Eliezer says: If one said: I swear that I shall not eat this loaf, one may establish an eiruv for him with it; but if he said: This loaf shall be forbidden to me, one may not establish an eiruv for him with it.
ומי אמר רבי אליעזר הכי והתניא זה הכלל אדם אוסר עצמו באוכל מערבין לו בה אוכל הנאסר לו לאדם אין מערבין לו בה רבי אליעזר אומר ככר זו עלי מערבין לו בה ככר זו הקדש אין מערבין לו בה לפי שאין מערבין לו בהקדשות
The Gemara asks: Did Rabbi Eliezer really say this? Wasn’t it taught in a baraita: This is the principle: With regard to a person who prohibits himself from eating a particular food, e.g., if one said: I swear that I shall not eat this loaf, one may establish an eiruv for him with that loaf. However, if the food was prohibited to a person, e.g., if he said: This loaf shall be forbidden to me, one may not establish an eiruv for him with it. Rabbi Eliezer says: If he said: This loaf shall be forbidden to me, one may establish an eiruv for him with it. However, if he said: This loaf is consecrated property, one may not establish an eiruv for him with it, as one may not establish an eiruv for him with consecrated objects. Therefore, Rabbi Eliezer does not distinguish between the two differently worded types of vows, but between a vow and consecration.
תרי תנאי ואליבא דרבי אליעזר:
The Gemara answers: It must be explained that these are two tanna’im who both held according to Rabbi Eliezer. Two later tanna’im disagreed with each other in reporting Rabbi Eliezer’s opinion.
מערבין לנזיר ביין כו׳: מתניתין דלא כבית שמאי דתניא בית שמאי אומרים אין מערבין לנזיר ביין ולישראל בתרומה בית הלל אומרים מערבין לנזיר ביין ולישראל בתרומה אמרו להן בית הלל לבית שמאי אי אתם מודים
We learned in the mishna: One may establish an eiruv for a nazirite with wine and for an Israelite with teruma, even though they themselves may not partake of these foods. The Gemara comments: The mishna was not taught in accordance with the opinion of Beit Shammai, as it was taught in a baraita that Beit Shammai say: One may not establish an eiruv for a nazirite with wine and for an Israelite with teruma. Beit Hillel disagree and say: One may establish an eiruv for a nazirite with wine and for an Israelite with teruma. Beit Hillel said to Beit Shammai: Do you not concede
שמערבין לגדול ביום הכפורים
that one may establish an eiruv for an adult even on Yom Kippur, despite the fact that he may not eat on Yom Kippur? It must be because eating is permitted to a minor.
אמרו להן אבל אמרו להן כשם שמערבין לגדול ביום הכפורים כן מערבין לנזיר ביין ולישראל בתרומה
Beit Shammai said to them: Indeed [aval], it is so. Beit Hillel said to them: Just as one may establish an eiruv for an adult on Yom Kippur, so too, one may establish an eiruv for a nazirite with wine and for an Israelite with teruma.
ובית שמאי התם איכא סעודה הראויה מבעוד יום הכא ליכא סעודה הראויה מבעוד יום
And how do Beit Shammai explain the difference between these cases? The Gemara explains: There, with regard to Yom Kippur, there is at least a meal that was fit to be eaten by that person while it was still day, on the eve of Yom Kippur. Here, in the cases of wine for a nazirite and teruma for an Israelite, there is no meal that was fit to be eaten by them while it was still day, on Friday.
כמאן דלא כחנניה דתניא חנניה אומר כל עצמן של בית שמאי לא היו מודים בעירוב עד שיוציא מטתו וכל כלי תשמישיו לשם
The Gemara asks: In accordance with whose opinion was that entire baraita stated? It was not taught in accordance with the opinion of Ḥananya, as it was taught in another baraita that Ḥananya says: The whole view of Beit Shammai, i.e., their fundamental position, was that they did not concede to the very possibility of joining Shabbat borders [eiruv teḥumin] by simply placing food in a particular location. Rather, they hold that one’s Shabbat residence remains the same until he literally moves his residence, such as if he carries out his bed and his utensils to there, to a new location.
כמאן אזלא הא דתניא עירב בשחורים לא יצא בלבנים בלבנים לא יצא בשחורים כמאן אמר רב נחמן בר יצחק חנניה היא ואליבא דבית שמאי
The Gemara asks: In accordance with whose opinion is the ruling that was taught in the following baraita: If one established an eiruv in black clothing, and Shabbat commenced while he was still dressed those clothes, he may not go out in white clothing. If one established the eiruv while dressed in white, he may not go out in black. According to whose opinion is this halakha? Rav Naḥman bar Yitzḥak said: It is the opinion of Ḥananya, and it is in accordance with the opinion of Beit Shammai.
ולחנניה בשחורים הוא דלא יצא הא בלבנים יצא האמר עד שיוציא מטתו וכלי תשמישיו לשם הכי קאמר עירב בלבנים והוצרך לשחורים אף בלבנים לא יצא כמאן אמר רב נחמן בר יצחק חנניה היא ואליבא דבית שמאי:
The Gemara asks: And according to the opinion of Ḥananya, is it with black clothing that he may not go out, but in white clothing he may go out? Didn’t Ḥananya say that according to Beit Shammai an eiruv is not effective at all until one carries out his bed and his utensils to the place he wishes to establish as his residence? The Gemara answers: The wording of the baraita must be emended and this is what it said: If one established an eiruv while dressed in white clothing, and he needed black clothing but did not have it with him, he may not go out even in white clothing. In accordance with whose opinion was this baraita taught? Rav Naḥman bar Yitzḥak said: It is the opinion of Ḥananya, and it is in accordance with the opinion of Beit Shammai.
סומכוס אומר בחולין: ואילו לנזיר ביין לא פליג מאי טעמא אפשר דמתשיל אנזירותיה
We learned in the mishna: Summakhos disagrees and says: One may not establish an eiruv for an Israelite with teruma, but only with regular, non-sacred food items. The Gemara notes: But with regard to the mishna’s ruling that an eiruv may be established for a nazirite with wine, Summakhos does not appear to disagree. What is the reason for the distinction? The Gemara explains: A nazirite can ask a Sage to annul his vow and release him from his nazirite status, and then he himself will be able to drink the wine.
אי הכי תרומה נמי אפשר דמיתשיל עילויה אי מתשיל עלה הדרא לטיבלא
The Gemara asks: If so, in the case of teruma as well, one can ask a Sage to annul its status. Teruma is consecrated through a verbal declaration by the one separating it, and that declaration, like other consecrations and vows, can be nullified by a Sage. The Gemara answers: Such a course of action would not help. If one asks a Sage to annul his declaration that turned the produce into teruma, the produce will return to its status as tevel, produce from which the requisite dues and tithes were not separated, and he will still be prohibited to consume it.
וליפרוש עלה ממקום אחר לא נחשדו חבירים לתרום שלא מן המוקף
The Gemara asks: Let him separate teruma for that produce from produce located somewhere else and thus permit it to be eaten. The Gemara answers: Ḥaverim, members of a group dedicated to the precise observance of mitzvot, are not suspected of separating teruma from produce that is not situated near the produce it comes to exempt, as this is prohibited ab initio.
ולפרוש עלה מיניה וביה דלית בה שיעורא
The Gemara asks: Let him separate teruma from the produce used for the eiruv itself and consequently permit the rest of the produce to be eaten. The Gemara answers: We are dealing with a case where, after removing teruma, it would not contain the amount required for an eiruv, i.e., one would be left with less than the quantity of food sufficient for two meals.
ומאי פסקא אלא סומכוס סבר לה כרבנן דאמרי כל דבר שהוא משום שבות גזרו עליו בין השמשות
The Gemara asks: What makes it necessary to say that the mishna is referring to this very unique case? Rather, we must retract all that was stated above and say as follows: Summakhos agrees with the opinion of the Rabbis, who say: Anything that is prohibited on Shabbat due to a rabbinic decree [shevut], the Sages issued the decree to apply even during twilight. Even though this period is of questionable status with regard to whether it is day or night, the Shabbat restrictions instituted by the Sages apply then as they do on Shabbat itself. Consequently, since it is prohibited to separate teruma on Shabbat, it is prohibited during the twilight period as well. Therefore, during twilight, when the eiruv would go into effect, it is impossible to cause it to become permitted to an Israelite.
כמאן אזלא הא דתנן יש שאמרו הכל לפי מה שהוא אדם מלא קומצו מנחה ומלא חפניו קטרת והשותה מלא לוגמיו ביום הכפורים ובמזון שתי סעודות לעירוב כמאן אמר רבי זירא סומכוס היא דאמר מאי דחזי ליה בעינן
The Gemara now asks: In accordance with whose opinion is the ruling that we learned in the following mishna: There are halakhot with regard to which they stated that measures are all in accordance with the particular person involved, e.g., the handful of flour that a priest scoops out from a meal-offering, and the handfuls of incense the High Priest would offer on Yom Kippur, and one who drinks a cheekful on Yom Kippur, and with regard to the measure of two meals’ worth of nourishment for an eiruv. All these measures are determined by the particular individual involved. In accordance with whose opinion is this halakha? Rabbi Zeira said: It is in accordance with the opinion of Summakhos, who said: We require that which is fit for him, the particular individual, and we do not follow a standard measure.
לימא פליגא אדרבי שמעון בן אלעזר דתניא רבי שמעון בן אלעזר אומר מערבין לחולה ולזקן כדי מזונו ולרעבתן בסעודה בינונית של כל אדם
The Gemara suggests: Let us say that the aforementioned mishna disagrees with the opinion of Rabbi Shimon ben Elazar. As it was taught in a baraita: Rabbi Shimon ben Elazar says: One may establish an eiruv for an ill or elderly person with an amount of food that is enough for him for two meals; and if he eats less than the average amount due to his sickness or age, a smaller amount of food is sufficient. But for a glutton we do not require food in an amount that would satisfy him; we measure on the basis of an average meal for the typical person.
תרגומא אחולה וזקן אבל רעבתן בטלה דעתו אצל כל אדם:
The Gemara answers: When the mishna says that the measure of food for two meals is determined by the particular person involved, interpret that as referring to an ill or elderly person. But with regard to a glutton, we do not determine the measure of food by his standard for a different reason, namely because his opinion is rendered irrelevant by the opinions of all other people. Therefore, there is no reason to be stringent with him and determine the measure according to his particular needs.
ולכהן בבית הפרס: דאמר רב יהודה אמר שמואל מנפח אדם בית הפרס והולך רבי יהודה בר אמי משמיה דרב יהודה אמר בית הפרס שנידש טהור:
We learned in the mishna: One may establish an eiruv for a priest in a beit haperas, an area in which there is doubt concerning the location of a grave or a corpse. The Gemara explains that the reason for this is as Rav Yehuda said that Shmuel said: In a time of need a person may blow on the dust in a beit haperas before taking each step, so that if there is a bone beneath the dust he will expose it and avoid it, and he may thus walk across the area. Similarly, Rabbi Yehuda bar Ami said in the name of Rav Yehuda: A beit haperas that has been trodden underfoot, creating a path, is pure, as we assume that it no longer contains any bones as large as a kernel of barley. Both of these statements indicate that the ritual impurity of a beit haperas is a stringency decreed by the Sages. Therefore, since there is a way to avoid becoming ritually impure there, even a priest may place his eiruv in a beit haperas.
רבי יהודה אומר אף בית הקברות: תנא מפני שיכול לחוץ ולילך בשידה תיבה ומגדל קא סבר אהל זרוק שמיה אהל
We learned in the mishna that Rabbi Yehuda says: An eiruv may be established for a priest even in a cemetery, an area which the priest may not enter by Torah law. It was taught: This is permitted because the priest can interpose and walk between the graves inside a carriage, a crate, or a cupboard. These containers do not contract impurity because of their large size, and anything found inside of them remains pure. From here we see that he holds the following: A moving tent is called a tent, and therefore the carriage, box, or cupboard are also considered tents. They shield a person carried in them from the impurity imparted by the graves in a cemetery.
ובפלוגתא דהני תנאי דתניא הנכנס לארץ העמים בשידה תיבה ומגדל רבי מטמא רבי יוסי ברבי יהודה מטהר
The Gemara notes that this matter is the subject of a dispute between the following tanna’im, as it was taught in a baraita: With regard to one who enters the land of the nations, i.e., any territory outside Eretz Yisrael, not on foot, but in a carriage, a crate, or a cupboard, Rabbi Yehuda HaNasi renders him ritually impure. Rabbi Yosei, son of Rabbi Yehuda, renders him pure.
במאי קמיפלגי מר סבר אהל זרוק לאו שמיה אהל ומר סבר אהל זרוק שמיה אהל
The Gemara explains: With regard to what do they disagree? One Sage, Rabbi Yehuda HaNasi, holds that a moving tent is not called a tent. The principle is that only something fixed can shield against ritual impurity, but if one is situated inside a portable vessel, the vessel contracts impurity and he becomes impure along with it. And the other Sage, Rabbi Yosei, son of Rabbi Yehuda, holds that a moving tent is called a tent, and it shields the person inside from contracting ritual impurity.
והא דתניא רבי יהודה אומר
And with regard to that which was taught in a baraita: Rabbi Yehuda says:
