Jerusalem Talmud Shabbat 21:3

משנה: בֵּית הִלֵּל אוֹמְרִין מַעֲבִירִין מֵעַל הַשּׁוּלְחָן עֲצָמוֹת וּקְלִיפִּין וּבֵית שַׁמַּאי אוֹמְרִין מְסַלֵּק אֶת הַטַּבֶּלָּה כוּלָּהּ וְנוֹעֲרָהּ. מַעֲבִירִין מֵעַל הַשּׁוּלְחָן פֵּירוּרִין פָּחוֹת מִכַּזַּיִת. שֵׂיעָר שֶׁל אֲפוּנִים וְשֶׁל עֲדָשִׁים מִפְּנֵי שֶׁהוּא מַאֲכַל בְּהֵמָה סְפוֹג אִם יֶשׁ לוֹ עוֹר בֵּית אֲחִיזָה מְקַנְּחִין בּוֹ. וְאִם לָאו אֵין מְקַנְּחִין בּוֹ. וַחֲכָמִים אוֹמְרִים בֵּין כָּךְ וּבֵין כָּךְ נִיטָּל בַּשַּׁבָּת וְאֵינוֹ מְקַבֵּל טוּמְאָה׃ MISHNAH: The House of Hillel say, one removes from the table bones and shells⁷These belong to the garbage and as such should be muqṣeh. The House of Hillel follow R. Simeon who restricts the notion of muqṣeh to things not usable at the start of the Sabbath. (The Mishnah in the Babli switches the statement of the Houses of Hillel and Shammai, but this is immediately corrected in the Babli’s Halakhah.), but the House of Shammai say, one removes the entire table and shakes it⁸Latin tabula, -ae, f. Since the table (or the table top if not attached to the legs) may be moved on the Sabbath, the statement of the House of Shammai follows the rule established in Mishnah 1.. One removes from the table crumbs less than olive size, hair⁹The shell. of chick-peas and lentils, since it is animal feed. One cleans with a sponge¹⁰Greek σπόγγος, ὁ. if it has a leather handle; otherwise one does not clean with it¹¹Since squeezing water out of the sponge would be biblically forbidden, one may clean the table only with a sponge that has a handle and was not wetted, when it is presumed that cleansing without squeezing is possible.. The Sages say in any case it may be taken on the Sabbath¹²Even if it has no handle it is an implement and can be moved on the Sabbath. and is impervious to impurity¹³The sponge is neither wood, nor metal, nor earthenware, nor textile, and therefore not of material susceptible to impurity..
