## Eruvin Daf 83a

###### Eruvin 83a:1
[Eruvin 83a:1](https://torahapp.org/share/book/Eruvin/r/83a:1)

תָּנָא: וַחֲצִי חֲצִי חֶצְיָהּ לְטַמֵּא טוּמְאַת אוֹכָלִין. וְתַנָּא דִּידַן מַאי טַעְמָא לָא תָּנֵי טוּמְאַת אוֹכָלִין? מִשּׁוּם דְּלָא שָׁווּ שִׁיעוּרַיְיהוּ לַהֲדָדֵי.

**William Davidson Edition - English:**
A Sage **taught** in the *Tosefta*: **And half of one half of its half,** one-eighth of this loaf, is the minimum measure of food that **contracts the** ritual **impurity of foods.** The Gemara asks: **And our *tanna*,** in the mishna, for **what reason** did **he did not teach** the measure of **the impurity of foods?** The Gemara answers: He did not state this *halakha* **because their measures are not** precisely **identical.** The measure for the impurity of foods is not exactly half the amount of ritually impure food that disqualifies one from eating *teruma*.


###### Eruvin 83a:2
[Eruvin 83a:2](https://torahapp.org/share/book/Eruvin/r/83a:2)

דְּתַנְיָא: כַּמָּה שִׁיעוּר חֲצִי פְרָס? שְׁתֵּי בֵיצִים חָסֵר קִימְעָא, דִּבְרֵי רַבִּי יְהוּדָה. רַבִּי יוֹסֵי אוֹמֵר: שְׁתֵּי בֵיצִים שׂוֹחֲקוֹת. שִׁיעֵר רַבִּי, שְׁתֵּי בֵיצִים וָעוֹד. כַּמָּה וָעוֹד? אֶחָד מֵעֶשְׂרִים בַּבֵּיצָה.

**William Davidson Edition - English:**
**As it was taught** in a *baraita*: **How much is half a *peras*? Two eggs minus a little;** this is **the statement of Rabbi Yehuda. Rabbi Yosei says: Two large eggs,** slightly larger ones than average. **Rabbi** Yehuda HaNasi **measured** the amount of half a *peras* after calculating the number of *kav* in the *se’a* brought before him, and found it to be **a little more than two eggs.** The *tanna* asks: **How much** is this **little more? One-twentieth of an egg.**


###### Eruvin 83a:3
[Eruvin 83a:3](https://torahapp.org/share/book/Eruvin/r/83a:3)

וְאִילּוּ גַּבֵּי טוּמְאַת אוֹכָלִין תַּנְיָא: רַבִּי נָתָן וְרַבִּי דּוֹסָא אָמְרוּ: כְּבֵיצָה שֶׁאָמְרוּ כָּמוֹהָ וְכִקְלִיפָּתָהּ, וַחֲכָמִים אוֹמְרִים: כָּמוֹהָ בְּלֹא קְלִיפָּתָהּ.

**William Davidson Edition - English:**
**In contrast, concerning the impurity of foods, it was taught** in a *baraita*: **Rabbi Natan and Rabbi Dosa said** that the measure of **an egg-bulk, which** the Sages **said** is the amount that contracts the impurity of foods, is **equivalent to it,** i.e., the egg, **and its shell. And the Rabbis say:** It is **equivalent to it without its shell.** These amounts are not precisely half of any of the measurements given for half a *peras*.


###### Eruvin 83a:4
[Eruvin 83a:4](https://torahapp.org/share/book/Eruvin/r/83a:4)

אָמַר רַפְרָם בַּר פָּפָּא אָמַר רַב חִסְדָּא: זוֹ דִּבְרֵי רַבִּי יְהוּדָה וְרַבִּי יוֹסֵי. אֲבָל חֲכָמִים אוֹמְרִים: כְּבֵיצָה וּמֶחֱצָה שׂוֹחֲקוֹת. וּמַאן חֲכָמִים — רַבִּי יוֹחָנָן בֶּן בְּרוֹקָה.

**William Davidson Edition - English:**
As for the issue itself, **Rafram bar Pappa said** that **Rav Ḥisda said: This** *baraita* that clarifies the measure of half a *peras* is in accordance with **the statements of Rabbi Yehuda and Rabbi Yosei,** a measure that is identical to that of Rabbi Shimon in the mishna. **But the Rabbis say: One and one half large egg-bulks. And who are** these **Rabbis? Rabbi Yoḥanan ben Beroka.**


###### Eruvin 83a:5
[Eruvin 83a:5](https://torahapp.org/share/book/Eruvin/r/83a:5)

פְּשִׁיטָא! שׂוֹחֲקוֹת אֲתָא לְאַשְׁמוֹעִינַן.

**William Davidson Edition - English:**
The Gemara registers surprise: This is **obvious,** as Rabbi Yoḥanan ben Beroka maintains that half a loaf is three egg-bulks, half of which is an egg-bulk and one half. The Gemara explains: The novel aspect of this teaching is not the amount itself; rather, **he came to teach us** that the measurement is performed with **large eggs.**


###### Eruvin 83a:6
[Eruvin 83a:6](https://torahapp.org/share/book/Eruvin/r/83a:6)

כִּי אֲתָא רַב דִּימִי, אָמַר: שִׁיגֵּר בּוֹנְיוֹס לְרַבִּי מוֹדְיָא דְקוֹנְדֵּיס דְּמִן נְאוּסָא, וְשִׁיעֵר רַבִּי מָאתַן וּשְׁבַע עֶשְׂרֵה בֵּיעִין.

**William Davidson Edition - English:**
The Gemara relates that **when Rav Dimi came** from Eretz Yisrael to Babylonia, **he said:** A person named **Bonyos sent Rabbi** Yehuda HaNasi **a measure [***modya***] of a *se’a* from** a place called **Na’usa,** where they had a tradition that it was an ancient and accurate measure (Ritva). **And Rabbi** Yehuda HaNasi **measured** it and found it contained **217 eggs.**


###### Eruvin 83a:7
[Eruvin 83a:7](https://torahapp.org/share/book/Eruvin/r/83a:7)

הָא סְאָה דְּהֵיכָא? אִי דְּמִדְבָּרִית, מֵאָה אַרְבָּעִים וְאַרְבַּע הָוְיָא!

**William Davidson Edition - English:**
The Gemara asks: **This *se’a*, from where** is it, i.e., on what measure is it based? **If** it is based on **the wilderness** *se’a*, the standard measure used by Moses in the wilderness, which is the basis for all the Torah’s measurements of volume, the difficulty is that a *se’a* is composed of six *kav*, where each *kav* is equivalent to four *log* and each *log* is equivalent to six egg-bulks. This means that a *se’a* **is** equivalent to a total of **144** egg-bulks.


###### Eruvin 83a:8
[Eruvin 83a:8](https://torahapp.org/share/book/Eruvin/r/83a:8)

וְאִי דִּירוּשַׁלְמִית, מֵאָה שִׁבְעִים וְשָׁלֹשׁ הָוְיָא!

**William Davidson Edition - English:**
**And if** it is **the Jerusalem** *se’a*, then the *se’a* **is** only **173** egg-bulks, as they enlarged the measures in Jerusalem by adding a fifth to the measures of the wilderness.


###### Eruvin 83a:9
[Eruvin 83a:9](https://torahapp.org/share/book/Eruvin/r/83a:9)

וְאִי דְּצִיפּוֹרִית, מָאתַיִם וְשֶׁבַע הָוְיָין!

**William Davidson Edition - English:**
**And if** it is a *se’a* **of Tzippori,** as the measures were once again increased in Tzippori, where another fifth was added to the Jerusalem measure, the *se’a* **is 207** egg-bulks. The *se’a* measured by Rabbi Yehuda HaNasi does not correspond to any of these measures of a *se’a*.


###### Eruvin 83a:10
[Eruvin 83a:10](https://torahapp.org/share/book/Eruvin/r/83a:10)

לְעוֹלָם דְּצִיפּוֹרִית, אַיְיתִי חַלְּתָא שְׁדִי עֲלַיְיהוּ.

**William Davidson Edition - English:**
The Gemara answers: **Actually,** this measure is based **on the** *se’a* **of Tzippori,** but you must **bring** the amount of **the *ḥalla*** given to a priest, **and add it to them.** That is to say, although this measure is slightly larger than a *se’a*, if it is used for flour and you deduct the amount due as *ḥalla*, you are left with exactly one *se’a*, or 207 egg-bulks.


###### Eruvin 83a:11
[Eruvin 83a:11](https://torahapp.org/share/book/Eruvin/r/83a:11)

חַלְּתָא כַּמָּה הָוְיָין? תַּמְנֵי, אַכַּתִּי בָּצַר לֵיהּ!

**William Davidson Edition - English:**
The Gemara raises an objection: The amount of ***ḥalla*, how many** egg-bulks **is it?** Approximately **eight** egg-bulks, one-twenty-fourth of 207. Yet in that case, **it remains less** than 217 egg-bulks, for even if we were to add another eight egg-bulks for *ḥalla* to the 207 egg-bulks, we would have only 215 egg-bulks, almost 216 to be more precise, which is still less than 217.


###### Eruvin 83a:12
[Eruvin 83a:12](https://torahapp.org/share/book/Eruvin/r/83a:12)

אֶלָּא אַיְיתִי וְעוֹדוֹת דְּרַבִּי שְׁדִי עֲלַיְיהוּ.

**William Davidson Edition - English:**
**Rather,** you must **bring** the **excess** amounts of **Rabbi** Yehuda HaNasi, the little more he included in his measure, **and add** these **to them.** In Rabbi Yehuda HaNasi’s calculations, he did not factor in the *ḥalla* that had to be separated. Instead, the egg-bulks he used to measure the *se’a* were small egg-bulks. Consequently, one-twentieth of an egg-bulk must be added for each egg-bulk. Since one-twentieth of 207 egg-bulks is roughly ten, the total amount equals 217 egg-bulks.


###### Eruvin 83a:13
[Eruvin 83a:13](https://torahapp.org/share/book/Eruvin/r/83a:13)

אִי הָכִי, הָוֵי לֵיהּ טְפֵי! כֵּיוָן דְּלָא הָוֵי כְּבֵיצָה, לָא חָשֵׁיב לֵיהּ.

**William Davidson Edition - English:**
The Gemara raises an objection: **If so, it is** still slightly **more** than 217 egg-bulks, by seven-twentieths of an egg-bulk, to be precise. The Gemara answers: **Since it is not** more than 217 egg-bulks by **a** whole **egg, he did not count it.**


###### Eruvin 83a:14
[Eruvin 83a:14](https://torahapp.org/share/book/Eruvin/r/83a:14)

תָּנוּ רַבָּנַן סְאָה יְרוּשַׁלְמִית יְתֵירָה עַל מִדְבָּרִית שְׁתוּת. וְשֶׁל צִיפּוֹרִית יְתֵירָה עַל יְרוּשַׁלְמִית שְׁתוּת. נִמְצֵאת שֶׁל צִיפּוֹרִית יְתֵירָה עַל מִדְבָּרִית שְׁלִישׁ.

**William Davidson Edition - English:**
**The Sages taught** in a *baraita*: **A Jerusalem *se’a* is larger than a wilderness** *se’a* **by one-sixth, and that of Tzippori is larger than a Jerusalem** *se’a* **by one-sixth. Consequently,** a *se’a* **of Tzippori is larger than a wilderness** *se’a* **by one-third.**


###### Eruvin 83a:15
[Eruvin 83a:15](https://torahapp.org/share/book/Eruvin/r/83a:15)

שְׁלִישׁ דְּמַאן? אִילֵּימָא שְׁלִישׁ דְּמִדְבָּרִית, מִכְּדִי שְׁלִישׁ דְּמִדְבָּרִית כַּמָּה הָוֵי — אַרְבְּעִין וּתְמָנְיָא, וְאִילּוּ עוּדְפָּא, שִׁיתִּין וּתְלָת.

**William Davidson Edition - English:**
The Gemara inquires: **One-third of which** measurement? **If you say** it means **one-third of a wilderness** *se’a*, **now** you must consider: **One-third of a wilderness** *se’a*, **how much is it? Forty-eight** egg-bulks, and **yet the difference** between the wilderness *se’a* and the Tzippori *se’a* is **sixty-three** egg-bulks. As stated above, a Tzippori *se’a* is 207 egg-bulks, whereas a wilderness *se’a* is only 144 egg-bulks.


###### Eruvin 83a:16
[Eruvin 83a:16](https://torahapp.org/share/book/Eruvin/r/83a:16)

וְאֶלָּא שְׁלִישׁ דִּירוּשַׁלְמִית: שְׁלִישׁ דִּידַהּ כַּמָּה הָוֵי — חַמְשִׁין וּתְמָנְיָא נְכֵי תִּילְתָּא, וְאִילּוּ עוּדְפָּא, שִׁתִּין וּתְלָת. וְאֶלָּא דְּצִיפּוֹרִי: שְׁלִישׁ דִּידַהּ כַּמָּה הָוֵי — שִׁבְעִין נְכֵי חֲדָא, וְאִילּוּ עוּדְפָּא, שִׁשִּׁים וְשָׁלֹשׁ.

**William Davidson Edition - English:**
**But rather,** this one-third mentioned in the *baraita* is referring to **one-third of a Jerusalem** *se’a*, which is 173 egg-bulks, as stated above. The Gemara again examines the calculation: **One-third of that** *se’a*, **how much is it? Fifty-eight less one-third,** and **yet the difference** between the wilderness and the Tzippori *se’a* is **sixty-three. Rather,** you must say that it is referring to one-third of a **Tzippori** *se’a*. **One-third of that** *se’a*, **how much is it? Seventy less one-third,** and **yet the difference** between the wilderness *se’a* and the Tzippori *se’a* is **sixty-three** egg-bulks. The difference between the measures is not exactly one-third according to any of the known *se’a* measurements.


###### Eruvin 83a:17
[Eruvin 83a:17](https://torahapp.org/share/book/Eruvin/r/83a:17)

אֶלָּא אָמַר רַבִּי יִרְמְיָה, הָכִי קָאָמַר: נִמְצֵאת סְאָה שֶׁל צִיפּוֹרִי יְתֵירָה עַל מִדְבָּרִית קָרוֹב לִשְׁלִישׁ שֶׁלָּהּ. וּשְׁלִישׁ שֶׁלָּהּ קָרוֹב לְמֶחֱצָה דְּמִדְבָּרִית.

**William Davidson Edition - English:**
**Rather, Rabbi Yirmeya said** that **this is** what the *tanna* **is saying: Consequently, a *se’a* of Tzippori is larger than a wilderness *se’a*** by sixty-three egg-bulks, which is **close to one-third of** a Tzippori *se’a* of sixty-nine egg-bulks. **And one-third of it,** sixty-nine egg-bulks, **is close to half of a wilderness** *se’a* of seventy-two egg-bulks.


###### Eruvin 83a:18
[Eruvin 83a:18](https://torahapp.org/share/book/Eruvin/r/83a:18)

מַתְקֵיף לַהּ רָבִינָא: מִידֵּי ״קָרוֹב״ ״קָרוֹב״ קָתָנֵי? אֶלָּא אָמַר רָבִינָא, הָכִי קָאָמַר: נִמְצֵאת שְׁלִישׁ שֶׁל צִיפּוֹרִי בִּוְעוֹדָיוֹת שֶׁל רַבִּי יְתֵירָה עַל מֶחֱצָה שֶׁל מִדְבָּרִית שְׁלִישׁ בֵּיצָה.

**William Davidson Edition - English:**
**Ravina raised an objection** to the opinion of Rabbi Yirmeya: **Does** the *baraita* **state** either: **Close** to one-third of a Tzippori *se’a* or: **Close** to half of a wilderness *se’a*? The wording of the *baraita* indicates an exact amount. **Rather, Ravina said** that **this is** what the *tanna* **is saying: Consequently, one-third of a Tzippori** *se’a* together **with the excess** amounts **of Rabbi** Yehuda HaNasi **is greater than half** of **a wilderness** *se’a* of seventy-two egg-bulks by only **one-third of an egg.** In other words, a Tzippori *se’a* of 207 egg-bulks added to the excess amounts of Rabbi Yehuda HaNasi of one-twentieth of an egg-bulk for each egg-bulk amounts to a total of 217 egg-bulks, one-third of which is seventy-two and one-third egg-bulks.

תָּנוּ רַבָּנַן: ״רֵאשִׁית עֲרִיסוֹתֵיכֶם״,

**William Davidson Edition - English:**
**Our Sages taught** a *baraita*: The verse states: “You shall set apart a cake of **the first of your dough** as a gift; like the gift of the threshing floor, so shall you set it apart” (Numbers 15:20).
