Shabbos16: 3
מַצִּילִין סַל מָלֵא כִכָּרוֹת — וְאַף־עַל־פִּי שֶׁיֵּשׁ בּוֹ מֵאָה סְעוּדוֹת — וְעִגּוּל שֶׁל דְּבֵלָה, וְחָבִית שֶׁל יַיִן. וְאוֹמֵר לַאֲחֵרִים: ,,בֹּאוּ וְהַצִּילוּ לָכֶם.“ וְאִם הָיוּ פִקְחִין, עוֹשִׂין עִמּוֹ חֶשְׁבּוֹן אַחַר הַשַּׁבָּת. לְהֵיכָן מַצִּילִין אוֹתָן? לְחָצֵר הַמְעֹרֶבֶת. בֶּן בְּתֵירָא אוֹמֵר: אַף לְשֶׁאֵינָהּ מְעֹרֶבֶת.
We may save a basket full of loaves — even though there is [enough] in it for one hundred meals — or a round cake of pressed figs, or a barrel of wine. And one may say to others, ‘‘Come and save for yourselves.’’ If they were discerning, they would make a reckoning with him after the Sabbath. To where may they take them for safety? To a courtyard provided with an eruv. Ben Beseira says: Even to one not provided with an eruv.
