שְׁלשָׁה דְבָרִים רַבָּן גַּמְלִיאֵל מַחֲמִיר כְּדִבְרֵי בֵית שַׁמַּאי, אֵין טוֹמְנִין אֶת הַחַמִּין מִיּוֹם טוֹב לַשַּׁבָּת, וְאֵין זוֹקְפִין אֶת הַמְּנוֹרָה בְיוֹם טוֹב, וְאֵין אוֹפִין פִּתִּין גְּרִיצִין אֶלָּא רְקִיקִין. אָמַר רַבָּן גַּמְלִיאֵל, מִימֵיהֶן שֶׁל בֵּית אַבָּא לֹא הָיוּ אוֹפִין פִּתִּין גְּרִיצִין, אֶלָּא רְקִיקִין. אָמְרוּ לוֹ, מַה נַּעֲשֶׂה לְבֵית אָבִיךָ, שֶׁהָיוּ מַחֲמִירִין עַל עַצְמָן וּמְקִלִּין לְכָל יִשְׂרָאֵל, לִהְיוֹת אוֹפִין פִּתִּין גְּרִיצִין וְחֹרִי:
In three things R. Gamliel adopts the stringent view, as per the ruling of Beth Shammai: Hot food may not be stored (to be kept warm) from yom tov to Shabbath. [For Beth Shammai hold that one may not bake (on yom tov) unless he has made an eruv with a loaf, and he may not cook unless he has made an eruv with a (cooked) dish, and he may not store food (to be kept warm) unless he had warm food stored from yom tov eve. And Beth Hillel hold that one may bake and cook and store on an eruv of cooked food alone. However, in the gemara it is indicated that Beth Hillel also require loaf and meat. And this is the halachah.] And a menorah is not set up on yom tov. If a menorah of linked sections came apart, it is not set up again; for this is like building, and (interdicted) "building" obtains with vessels. And Beth Hillel hold that "building" does not obtain with vessels.] And loaves are not baked thick (on yom tov), but thin. [Beth Shammai hold that it is forbidden to bake large loaf on yom tov, and Beth Hillel hold that it is permitted, for when it is large, it bakes better.] R. Gamliel said: "All the days of my father's house, they never baked thick loaves but only thin ones." They responded: "What can we do for your father's house, who were stringent with themselves and lenient with all of Israel, allowing them to bake thick loaves and chori [a large piece of dough baked on coals, requiring much lighting, for the coals keep on going out, and exertion is entailed. The halachah is not in accordance with R. Gamliel in respect to all of his stringencies as per Beth Shammai.]
