Yerushalmi Eruvin 6:5 ירושלמי עירובין ו׳:ה׳

MISHNAH: If the owner of a house participated with several neighbors with wine, they do not need to make an eruv. If with wine with one but oil with the other they need to make an eruv. Rebbi Simeon says neither of them has to make an eruv¹³If all the people living around a courtyard or in an alley are in business together and own wine stored at one place in their courtyard or alley they do not need an eruv since some of the wine might be used as common food. R. Simeon extends this to several kinds of food belonging to several people as long as the foods are sometimes used together as food.

HALAKHAH: Paragraph. “If the owner of a house participated with several neighbors,” etc. Rebbi Abba in the name of Rebbi⁹³Read: Rav. Jehudah: They stated this in commercial practice⁹⁴The language of the Mishnah is inconsistent. “Participation” refers to making an eruv in an alley, “neighbors” refer to dwellers in a courtyard. The Mishnah does not refer explicitly to either one; it uses the expression “participate” to describe partnership.. Everybody with wine, since he does not care about mixing⁹⁵Since everything is in a large vessel and the relative shares of the partners have not been separated., it does not need an eruv. If with wine with one but oil with the other, since he cares about mixing, it needs an eruv. Rebbi Abba bar Cahana, Rav Ḥiyya bar Ashi in the name of Rav: The Mishnah refers to the case that all is in one vessel⁹⁶Babli 71a. Since it is not intentionally collected as eruv but is used as such because it happened to be available, it must be in one vessel.. Rebbi Zeriqan said, the reason of Rebbi Simeon is that they are used to drink οἰνόγαρον⁹⁷“Wine-fish sauce”.. It was stated⁹⁸Tosephta 5:9, Babli 71b.: Rebbi Eleazar ben Thaddeus says, in every case they are forbidden until they make an eruv. Rebbi Aḥa in the name of Rav: Practice follows Rebbi Eleazar ben Thaddeus. Rebbi Jacob bar Aḥa in the name Rebbi Ze`ira: Rebbi Eleazar ben Thaddeus follows Rebbi Meïr. Which [statement of] Rebbi Meïr? Rebbi Mana said, Rebbi Meïr who said, by an eruv, by participation<sup>99</sup>Tosephta 6:6. He requires separate participation in an alley and eruv for courtyards in all cases.. Rebbi Yose ben Rebbi Abun said, Rebbi Meïr who said that one may not make an eruv for a person without his knowledge<sup>100</sup>Mishnah 7:11.. In the opinion of Rebbi Mana, following Rebbi Ze`ira, in the opinion of Rav following Rebbi Meïr¹⁰¹R. Mana interprets the statement of R. Ze`ira to imply that Rav accepts the position of R. Meïr.. Rebbi Ze`ira in the name of Rebbi Joḥanan: In matters of eruvin and public fast-days everybody follows Rebbi Meïr. Rebbi Jacob bar Aḥa in the name Rebbi Joḥanan: Even about the reading of the Esther scroll everybody follows Rebbi Meïr¹⁰²In eruvin one follows R. Meïr that eruv for courtyards and participation for alleys must be separate acts, later in the Chapter, 23d l. 47; then Ta`aniot 67b 4:1 l. 57 (that on a public fast day the priestly blessing is given three times), Megillah 2:1 73b l. 26 (that the scroll has to be read from beginning to end). Babli 72a. These rules are popular usage, not rabbinic decrees..
