Jerusalem Talmud Shabbat 16:6

משנה: רַבִּי שִׁמְעוֹן בֶּן נַנָּס אוֹמֵר פּוֹרְסִין עוֹר שֶׁל גְּדִי עַל גַּבֵּי שִׁידָּה תֵּיבָה וּמִגְדָּל שֶׁאָחַז בָּהֶם אֶת הָאוּר מִפְּנֵי שֶׁהוּא מְחָרֵךְ. עוֹשִׂין מְחִיצָּה בְּכָל־הַכֵּלִים בֵּין מְלֵאִים בֵּין רֵיקָנִין בִּשְׁבִיל שֶׁלֹּא תַעֲבֹר הַדְּלֵיקָה. רִבִּי יוֹסֵי אוֹסֵר בִּכְלֵי חֶרֶס חֲדָשִׁים מְלֵאִים מַיִם שֶׁאֵינָן יְכוֹלִין לְקַבֵּל בָּהֶן אֶת הָאוּר וְהֵן מִתְבַּקְּעִין וּמְכַבִּין אֶת הַדְּלֵיקָה: MISHNAH: Rebbi Simeon ben Nanas says, one spreads kid leather over a chest, a box, or a cupboard which are on fire since it is singed¹⁴It is not usually burned in a fire; therefore covering utensils with hide is not supplying the fire with fuel.. One builds a wall out of vessels¹⁵Since vessels are not building material, moving amphoras together to hinder the spread of the fire is not building., whether full or empty, lest the fire cross over. Rebbi Yose forbids new clay vessels full of water since they cannot withstand the heat, spring leaks, and extinguish the fire¹⁶If it is a foregone conclusion that the vessels will break and douse the fire, using a subterfuge is forbidden as long as one cannot go and extinguish the fire directly as a danger to life..

הלכה: כֵּינִי מַתְנִיתָא. מִשֶּׁיֶּאֱחוֹז הָאוּר בָּהֶן. רִבִּי יִרְמְיָה רִבִּי בָּא בַּר מָמָל בְּשֵׁם רַב. סֵפֶר שֶׁאָחַז בּוֹ הָאוּר מִצַּד אֶחָד נוֹתֵן מַיִם מִצַּד הַשֵּׁינִי. וְאִם כָּבָה כָבָה. אָחַז בּוֹ הָאוּר מִשְּׁנֵי צְדָדִין פּוֹשְׁטוֹ וְקוֹרֵא בוֹ. וְאִם כָּבָה כָבָה. טַלִּית שֶׁאָחַז בּוֹ הָאוּר מִצַּד אֶחָד נוֹתֵן מַיִם מִצַּד שֵׁינִי. וְאִם כָּבָה כָבָה. אָחַז בָּהּ הָאוּר מִשְּׁנֵי צְדָדִין נוֹטְלָהּ וּמִתְעַטֵּף בָּהּ. וְאִם כָּֽבְתָה כָֽבְתָה. HALAKHAH: So is the Mishnah: Before they are on fire¹¹⁹This refers to Shabbat 16:6:1" href="/Jerusalem_Talmud_Shabbat.16.6.1">Mishnah 6. Ben Nanas only allows protecting the chest from the fire, not smothering it with a leather cover.. Rebbi Jeremiah, Rebbi Abba bar Mamal in the name of Rav: If a scroll started burning at one side one puts water on the other side¹²⁰This is indirect causation of extinguishing which only is rabbinically forbidden and is tolerated in this case.; if it was extinguished it was extinguished. If the fire burned on both sides one spreads it out and reads in it; if it was extinguished it was extinguished. ¹²¹Shabbat.120a">Babli 120a bottom. If a toga started burning at one side one puts water on the other side; if it was extinguished it was extinguished. If the fire burned on both sides one takes it and wraps oneself in it; if it was extinguished it was extinguished.

רִבִּי שְׁמוּאֵל בְּשֵׁם רִבִּי זֵירָא. דְּרִבִּי יוֹסֵה הִיא. אָמַר רִבִּי יוֹסֵה. הֲוָה סָבְרִינַן מֵימַר. מַה פְלִיגִין מֵימַר רִבִּי יוֹסֵה וְרַבָּנִן. בְּשֶׁעָשָׂה מְחִיצָה שֶׁלְּכֶלִים. אֲבָל אִם עָשָׂה מְחִיצָה שֶׁל מַיִם לֹא. מִמָּה דָמַר רִבִּי שְׁמוּאֵל בְּשֵׁם רִבִּי זְעִירָא. דְּרִבִּי יוֹסֵי הִיא. הָדָא אָֽמְרַה. אֲפִילוּ עָשָׂה מְחִיצָה שֶׁלְּמַיִם הִיא הַמַחֲלוֹקֶת. ¹²²This is copied from the end of Shabbat 3:8:3" href="/Jerusalem_Talmud_Shabbat.3.8.3">Chapter 3, Note 234. Rebbi Samuel in the name of Rebbi Zeˋira: This is Rebbi Yose’s. We were of the opinion to say, where what Rebbi Yose says and the rabbis disagree? When he made a barrier of vessels. But not if he made a barrier of water. Since Rebbi Samuel said in the name of Rebbi Zeˋira: This is Rebbi Yose’s, it implies that there is disagreement even if he made a barrier of water.
