Talmud sur Mo'ed Katan 2:11

HALAKHAH: “When is he guilty,” etc. Rebbi Yose said²⁰The Amora R. Yose determines the amount required by the Sages as half that indicated by the Tanna R. Yose, a statement ascribed in the Babli to his teacher’s teacher R. Zeˋira. His statement implies that, as a weight, a mina (100 drachmas) was identified with the pound of 12 ounces, i. e. 96 denars. Since other talmudic data indicate that as a coin, drachma in the Eastern Roman Empire was the name of the silver denar, one has to assume that mina as a weight simply was a name for the Roman pound. [D. Sperber (Roman Palestine 200–400, Money and Prices, Ramat Gan 1974) consistently writes mina for the weight and maneh for the coin. But since a talmudic מנה always denotes 100 denars, there is no reason not to read the word as Μνᾶ, מְנָה.], the fourfold portion is half a Roman pound.

³⁸The origin of these paragraphs is Halakhah Beṣah 5:1 (י). Not only is the subject of muqṣeh the main topic of this Tractate but also the somewhat difficult Aramaic of the last sentence is copied correctly in Beṣah but defectively here. The second paragraph also is copied later in Chapter 13 (13). Rav Jeremiah in the name of Rav: One spreads a mat over rows of bricks on the Sabbath³⁹Even though the bricks are there as building materials one may turn them into seats if needed since they are not moved. In the Babli’s theory, muqṣeh items may not be moved, but they may be touched. It does not seem that this is the Yerushalmi’s attitude, as expressed by Rav in the question of the hunters. Nevertheless here the bricks are not touched; people sit on the mat. Babli 43a, Beṣah 36a. In the reading of the Babli this is a Tannaitic statement and the bricks are not there for a future building project but are leftovers from a finished one..

HALAKHAH: Rebbi Ḥananiah in the name of Rebbi Joḥanan: They permitted its end because of its beginning. Since if you would tell him that he may not finish he would not open¹⁹¹If the grocer is not sure that he may sell the entire contents of a new barrel, nobody would expect him to supply wine or oil towards the end of the holiday.. Let him not open! Then he diminishes the enjoyment of the holiday.
