['A person may take his son in his hands on Shabbat, and even though there is a stone, which is a set-aside item, in the child’s hand, it is not prohibited to pick up the child. And it is permissible to take a basket with a stone inside it on Shabbat. And one may move ritually impure teruma, which may not be eaten and is set-aside, with ritually pure teruma, as well as with non-sacred produce. Rabbi Yehuda says: One may even lift a measure of teruma that was nullified from a mixture of one hundred measures of non-sacred produce and one measure of teruma. When a measure of teruma is mixed with non-sacred produce, if the non-sacred produce is one hundred times the measure of teruma, the teruma is nullified. However, the Sages instituted that one must remove an amount equivalent to that measure of teruma and give it to a priest. The remainder is considered non-sacred produce. Rabbi Yehuda permits removing that measure on Shabbat to render the mixture permitted to eat.', 'With regard to a stone, which is set-aside on Shabbat and may not be moved, that was placed on the mouth of a barrel, one tilts the barrel on its side, and the stone falls. If the barrel was among other barrels, and the other barrels might break if the stone falls on them, he lifts the barrel to distance it from the other barrels, and then tilts it on its side, and the stone falls. With regard to coins that are on a cushion, he shakes the cushion and the coins fall. If there was bird dung (Arukh) on the cushion, he wipes it with a rag, but he may not wash it with water because of the prohibition against laundering. If the cushion was made of leather, and laundering is not a concern, he places water on it until the bird dung ceases.', 'Beit Shammai say: One may clear bones and shells left from the Shabbat meal from the table with his hand. And Beit Hillel say: One may remove the entire board [tavla] that is the table surface and shake the bones and shells off of it, but he may not lift them with his hand because they are set-aside and may not be moved. One may clear bread crumbs from the table, even if they are less than an olive-bulk, and pea and lentil pods. Even though it is not fit for human consumption, it may be moved because it is animal fodder. With regard to a sponge, if it has leather as a handle, one may wipe the table with it, and if not, one may not wipe the table with it lest he come to squeeze liquid from it. And the Rabbis say: Both this, a dry sponge with a handle, and that, one without a handle, may be moved on Shabbat and it does not become ritually impure. A sponge is not among the substances that can become ritually impure, neither by Torah law nor by rabbinic decree.']
