Mishnà su Esodo 16:38

Shammai says: “[Dough] of a kav or more is subject to the law of hallah.” And Hillel says: “Of two kavs or more.” But the Sages say: “Neither according to the opinion of this one nor according to the opinion of this one, but [dough of] a kav and a half is subject to the law of hallah.” And after they increased the measures they said: “[Dough of] five quarters is subject. Rabbi Yose said: “Five are exempt, five and more are liable.”

The following cases are [examples] of the lenient rulings of Beth Shammai and of the rigorous rulings of Beth Hillel.An egg which is laid on a festival Beth Shammai says: it may be eaten, and Beth Hillel says: it may not be eaten. Beth Shammai says: yeast as much as an olive [in quantity], and leavened food as much as a date, and Beth Hillel says: as much as an olive [in quantity] in both cases.

Ten things were created on the eve of the Sabbath at twilight, and these are they: [1] the mouth of the earth, [2] the mouth of the well, [3] the mouth of the donkey, [4] the rainbow, [5] the manna, [6] the staff [of Moses], [7] the shamir, [8] the letters, [9] the writing, [10] and the tablets. And some say: also the demons, the grave of Moses, and the ram of Abraham, our father. And some say: and also tongs, made with tongs.

A flow pouring [from one vessel to another] is clean, except [the flow] of honey of ziphim bees and honey batter. Bet Shammai say: also [the flow of] thick pottage of split beans, because it thickens up backwards.
