אֵין שׁוֹבְרִין אֶת הַחֶרֶס, וְאֵין חוֹתְכִין אֶת הַנְּיָר לִצְלוֹת בּוֹ מָלִיחַ, וְאֵין גּוֹרְפִין תַּנּוּר וְכִירַיִם, אֲבָל מְכַבְּשִׁין, וְאֵין מַקִּיפִין שְׁתֵּי חָבִיּוֹת לִשְׁפֹּת עֲלֵיהֶן אֶת הַקְּדֵרָה, וְאֵין סוֹמְכִין אֶת הַקְּדֵרָה בְבַקַּעַת, וְכֵן בְּדֶלֶת, וְאֵין מַנְהִיגִין אֶת הַבְּהֵמָה בְמַקֵּל בְּיוֹם טוֹב, וְרַבִּי אֶלְעָזָר בְּרַבִּי שִׁמְעוֹן מַתִּיר:
One may not break a shard or cut paper [on which oil is put, so that it is fire-resistant] to roast a salted (fish), and an oven or a stove may not be scraped [If some of the plaster or lime of the stove fell into it, it may not be scraped, this being "amending a vessel." This ruling is in accordance with the rabbis, who say that "enabling labors" for eating are forbidden.], but it [the ash and the residue] may be leveled, [and if baking is impossible unless it is scraped, it is permitted.] And two barrels may not be put close together to place a pot upon them [with the fire between the two barrels, this being forbidden because it looks like "building"]. And a pot may not be supported with pieces of wood, [wood being used only for kindling]. And so with a door, [it may not be steadied with a piece of wood, wood being muktzeh for all uses except kindling.] And a beast may not be led with a stick on yom tov, [for the impression is given that it is being led to market to be sold]. R. Elazar b. R. Shimon permits it.
