Talmud for Shabbat 239:10
<big><strong>גמ׳</strong></big> אמר רב יהודה אמר רב טלית שאחז בה האור מצד אחד נותנין עליה מים מצד אחר ואם כבתה כבתה מיתיבי טלית שאחז בה האור מצד אחד פושטה ומתכסה בה ואם כבתה כבתה וכן ספר תורה שאחז בו האור פושטו וקורא בו ואם כבה כבה
<b><i>MISHNAH</i></b>. R. SIMEON B. NANNOS SAID: ONE MAY SPREAD A GOAT SKIN<span class="x" onmousemove="('comment',' Rashi: which is damp. ');"><sup>33</sup></span> OVER A BOX, CHEST, OR TRUNK<span class="x" onmousemove="('comment',' Lit., 'turret'. — Three kinds of boxes or chests are meant. ');"><sup>34</sup></span> WHICH HAS CAUGHT FIRE, BECAUSE HE SINGES;<span class="x" onmousemove="('comment',' But does not burn it and at the same time it protects the boxes. ');"><sup>35</sup></span> AND ONE MAY MAKE A BARRIER WITH ALL VESSELS, WHETHER FULL [OF WATER] OR EMPTY, THAT THE FIRE SHOULD NOT TRAVEL ONWARD. R. JOSE FORBIDS IN THE CASE OF NEW EARTHEN VESSELS FILLED WITH WATER, BECAUSE SINCE THEY CANNOT STAND THE HEAT, THEY WILL BURST AND EXTINGUISH THE FIRE.<span class="x" onmousemove="('comment',' Which is forbidden as a principal labour, v. supra 73a. ');"><sup>36</sup></span> <b><i>GEMARA</i></b>. Rab Judah said in Rab's name: If a garment catches fire on one side, water may be poured on to it on the other, and if it is [thereby] extinguished, it is extinguished. An objection is raised: If a garment catches fire on one side, one may take it off and cover himself with it, and if it is extinguished, if it extinguished; and likewise if a Scroll of the Law catches fire, one may spread it out and read it, and if it is extinguished, it is extinguished?<span class="x" onmousemove="('comment',' In each case probably the motion extinguishes it if the flame is very small. But the Tanna does not permit water. ');"><sup>37</sup></span>
