###### Eruvin 90b:1
[Eruvin 90b:1](https://torahapp.org/share/book/Eruvin/r/90b:1)

דְּהָא אִיכָּא מְחִיצָתָא. וּשְׁמוּאֵל אָמַר: אֵין מְטַלְטְלִין בָּהּ אֶלָּא בְּאַרְבַּע אַמּוֹת — מְחִיצוֹת לְהַבְרִיחַ מַיִם עֲשׂוּיוֹת.

**William Davidson Edition - English:**
**as there are partitions. And Shmuel said: One may move** an object **in it only within four cubits,** as **the partitions** of the ship are not considered full-fledged partitions; they **are erected** only **to keep water out,** not to render it a residence.


###### Eruvin 90b:2
[Eruvin 90b:2](https://torahapp.org/share/book/Eruvin/r/90b:2)

אֲמַר לֵיהּ רַב חִיָּיא בַּר יוֹסֵף לִשְׁמוּאֵל: הִילְכְתָא כְּווֹתָךְ אוֹ הִילְכְתָא כְּרַב? אֲמַר לֵיהּ: הִילְכְתָא כְּרַב.

**William Davidson Edition - English:**
**Rav Ḥiyya bar Yosef said to Shmuel:** Is **the *halakha* in accordance with your** opinion **or** is **the *halakha* in accordance with** the opinion of **Rav?** Shmuel **said to him: The *halakha* is in accordance with** the opinion of **Rav,** as his rationale is more convincing.


###### Eruvin 90b:3
[Eruvin 90b:3](https://torahapp.org/share/book/Eruvin/r/90b:3)

אָמַר רַב גִּידֵּל אָמַר רַב חִיָּיא בַּר יוֹסֵף: וּמוֹדֶה רַב שֶׁאִם כְּפָאָהּ עַל פִּיהָ, שֶׁאֵין מְטַלְטְלִין בָּהּ אֶלָּא בְּאַרְבַּע אַמּוֹת. כְּפָאָהּ, לְמַאי? אִילֵימָא לָדוּר תַּחְתֶּיהָ, מַאי שְׁנָא מִגַּג יְחִידִי?

**William Davidson Edition - English:**
**Rav Giddel said** that **Rav Ḥiyya bar Yosef said: And Rav concedes that if one overturned** the ship **onto its mouth,** and it is more than ten handbreadths high, **that one may move** an object **on it only within four cubits.** The Gemara asks: **For what** purpose **was** the ship **overturned? If you say** it was overturned so **that** one may **reside beneath it, what is the difference** between it and **an isolated roof?** The legal status of the overturned ship should in every sense be that of a house, and therefore it should be permitted to carry throughout the entire ship.


###### Eruvin 90b:4
[Eruvin 90b:4](https://torahapp.org/share/book/Eruvin/r/90b:4)

אֶלָּא שֶׁכְּפָאָהּ לְזוֹפְתָהּ.

**William Davidson Edition - English:**
**Rather,** it must be **that he overturned it to tar it,** i.e., to add a fresh coat to its underside. In that case, the boat certainly does not serve as a residence, and its sides are not considered full-fledged partitions.


###### Eruvin 90b:5
[Eruvin 90b:5](https://torahapp.org/share/book/Eruvin/r/90b:5)

רַב אָשֵׁי מַתְנֵי לַהּ אַסְּפִינָה, וְרַב אַחָא בְּרֵיהּ דְּרָבָא מַתְנֵי לַהּ אַאַכְסַדְרָא. דְּאִיתְּמַר, אַכְסַדְרָה בְּבִקְעָה. רַב אָמַר: מוּתָּר לְטַלְטֵל בְּכוּלָּהּ, וּשְׁמוּאֵל אָמַר: אֵין מְטַלְטְלִין בָּהּ אֶלָּא בְּאַרְבַּע.

**William Davidson Edition - English:**
**Rav Ashi teaches** Shmuel’s acceptance of Rav’s opposing view (Ritva) with regard **to a ship,** as stated above; **and Rav Aḥa, son of Rava, teaches it** with regard **to a portico, as it was stated** that *amora’im* disagreed with regard to **a portico** located **in a field.** A portico has a roof and either incomplete walls or no walls. Consequently, in the case of a portico located in a valley, which is a *karmelit*, it remains to be determined whether or not it is permitted to carry in it. **Rav said: It is permitted to move** an object **throughout the entire** portico, as it is a private domain. **And Shmuel said: One may move** an object **in it only within four** cubits.


###### Eruvin 90b:6
[Eruvin 90b:6](https://torahapp.org/share/book/Eruvin/r/90b:6)

רַב אָמַר: מוּתָּר לְטַלְטֵל בְּכוּלָּהּ — אָמְרִינַן פִּי תִקְרָה יוֹרֵד וְסוֹתֵם. וּשְׁמוּאֵל אָמַר: אֵין מְטַלְטְלִין בָּהּ אֶלָּא בְּאַרְבַּע — לָא אָמְרִינַן פִּי תִקְרָה יוֹרֵד וְסוֹתֵם.

**William Davidson Edition - English:**
The Gemara elaborates. **Rav said: It is permitted to move** an object **throughout the entire** portico, as **we say: The edge of the roof descends** to the ground **and seals** the portico on all sides, rendering it a private domain. **And Shmuel said: One may move** an object **in it only within four** cubits, as **we do not say: The edge of the roof descends** to the ground **and seals** the portico.


###### Eruvin 90b:7
[Eruvin 90b:7](https://torahapp.org/share/book/Eruvin/r/90b:7)

וְרַב אַלִּיבָּא דְּרַבִּי מֵאִיר, לִיטַּלְטְלֵי מִגַּג לְחָצֵר?! גְּזֵירָה מִשּׁוּם דְּרַב יִצְחָק בַּר אַבְדִּימִי.

**William Davidson Edition - English:**
The Gemara asks: **But** according to **Rav’s** statement **in accordance with** the opinion **of Rabbi Meir** that one is permitted to carry from one roof to another if they are level, it should also be permitted **to carry from a roof to a courtyard.** Why then does Rabbi Meir rule that roofs and courtyards are separate domains and that carrying between them is prohibited? The Gemara answers: It is prohibited because Rabbi Meir issued **a decree, due to** the opinion **of Rav Yitzḥak bar Avdimi.** As stated previously, Rav Yitzḥak bar Avdimi rules that one may not transfer objects between two halakhically equivalent but physically distinct domains ten or more handbreadths high. This is a decree lest one standing in a public domain adjust a burden on a mound ten handbreadths high and four handbreadths wide, which is a private domain, an act prohibited by Torah law.


###### Eruvin 90b:8
[Eruvin 90b:8](https://torahapp.org/share/book/Eruvin/r/90b:8)

וּשְׁמוּאֵל אַלִּיבָּא דְרַבָּנַן, נִיטַּלְטֵל מִגַּג לְקַרְפֵּף. אָמַר רָבָא בַּר עוּלָּא: גְּזֵירָה שֶׁמָּא יִפָּחֵת הַגָּג.

**William Davidson Edition - English:**
The Gemara continues: **And** according to **Shmuel’s** statement **in accordance with** the opinion **of the Rabbis** that the legal status of an isolated roof greater than two *beit se’a* is that of a *karmelit*, it should be permitted **to move** an object **from** an isolated **roof to an enclosure** within four cubits of the roof, as the legal status of the enclosure is also that of a *karmelit*. Why then do the Rabbis rule that roofs and enclosures are separate domains and carrying from one to the other is prohibited? **Rava bar Ulla said:** It is prohibited because the Rabbis issued **a decree lest the** area of the **roof diminish** to less than two *beit se’a*, in which case it would assume the status of a private domain, as it is prohibited to carry between a private domain and an enclosure.


###### Eruvin 90b:9
[Eruvin 90b:9](https://torahapp.org/share/book/Eruvin/r/90b:9)

אִי הָכִי, מִקַּרְפֵּף לְקַרְפֵּף נָמֵי לָא יְטַלְטֵל, דִּילְמָא מִיפְּחִית וְאָתֵי לְטַלְטוֹלֵי? הָתָם, אִי מִיפְּחִית מִינַּכְרָא לֵיהּ מִילְּתָא. הָכָא, אִי מִיפְּחִית לָא מִינַּכְרָא מִילְּתָא.

**William Davidson Edition - English:**
The Gemara asks: **If so, one should also not** be permitted to **move** an object **from one enclosure to** another **enclosure,** due to the concern that **perhaps** the area of one of the enclosures will **diminish** and become a private domain, **and he** will **come** to **move** an object from one to the other as before. The Gemara answers: **There, if** the enclosure **is diminished, the matter is conspicuous,** as its walls are clearly visible. **Here,** however, **if** the roof **is diminished, the matter is not conspicuous,** as the roof does not have walls.


###### Eruvin 90b:10
[Eruvin 90b:10](https://torahapp.org/share/book/Eruvin/r/90b:10)

אָמַר רַב יְהוּדָה: כְּשֶׁתִּמְצָא לוֹמַר, לְדִבְרֵי רַבִּי מֵאִיר גַּגִּין רְשׁוּת לְעַצְמָן, חֲצֵירוֹת רְשׁוּת לְעַצְמָן,

**William Davidson Edition - English:**
**Rav Yehuda said:** After careful analysis, **you will find** that you can **say** that **according to the statement of Rabbi Meir, roofs are a domain in and of themselves,** and one may carry from one roof to another; and likewise **courtyards are** considered **a domain in and of themselves,** and one may likewise carry from one courtyard to another.
