Mishnah Shabbat 20

¹R. Eliezer says: one may suspend a strainer on festivals, and pour [wine] through a suspended [strainer] on Shabbat. But the sages say: one may not suspend a strainer on festivals, nor pour [wine] through a suspended [strainer] on Shabbat, but one may pour [it] through a suspended [strainer] on festivals. ²One may pour water over lees in order to clarify them; and one may strain wine through cloths and through a basket made of palm twigs; and one may place an egg in a mustard strainer; and one may make anumlin on Shabbat. Rabbi Judah says: on Shabbat [it may only be made] in a cup; on festivals, in a jug; and on the intermediate days of festivals in a barrel. Rabbi Zadok says: it all depends on the [number of] guests. ³One may not soak hiltith in warm water, but he may put it into vinegar. And one may not soak leeks, nor rub them, but he may put them into a sieve or a basket. One may not sift straw through a sieve, nor put it on a high place, for the chaff to drop down, but one may take it up in a sieve and put it into the trough. ⁴One may rake out [the trough] for a stall ox, and move [the remnants] aside for the sake of a grazing [ox], the words of Rabbi Dosa. But the sages prohibit it. One may take [food] from one animal and place it before another animal on Shabbat. ⁵The straw [lying] upon a bed one may not move it with his hand, but he may move it with his body. But if it is animal feed, or a pillow or a sheet was upon it [on the eve of Shabbat], he may move it with his hand. A householder’s clothes press one may undo it, but not force it down. But a launderer’s [press] one may not touch it. Rabbi Judah says: if it was undone before Shabbat, one may unfasten the whole and remove it.
