ONE WHO WAS NOT ME'AREV (Yerushalmi Perek 6 Halachah 3 Daf 39a)

מתני' אנשי חצר ששכח אחד מהן ולא עירב ביתו אסור מלהכניס ולהוציא לו ולהם שלהם מותרין לו ולהן

(a)

(Mishnah): If one of the residents of a Chatzer forgot to give towards the Eruv, his house is forbidden [to transfer between it and the Chatzer] to him and to them (the Bnei Chatzer). Their houses are permitted to him and to them;

נתנו לו רשותן הוא מותר והן אסורין

(b)

If they gave their Reshus to him, he is permitted [to transfer between his house and the Chatzer], and they are forbidden [even from his house];

היו שנים אוסרין זה על זה שאחד נותן רשות ונוטל רשות ושנים נותנין רשות ואינן נוטלין רשות:

(c)

If two [forgot], they forbid each other. This is because one person can give or receive Reshus. Two can give Reshus but cannot receive it.

גמ' שלהם מותרין לו ולהם שביטל רשותו.

(d)

(Gemara): Their [houses] are permitted to him and to them. [The case is,] he was Mevatel his Reshus [in the Chatzer. He is like a guest staying with them.]

מהו שתחזיר חלילה

(e)

Question: [If two in a Chatzer did not make an Eruv, can one be Mevatel to the other, and the latter does his needs, and] can then they switch back (the latter is Mevatel to the first, so he can do his needs)?

תלמידוי דרב בשם רב חוזרת חלילה

(f)

Answer #1 (Rav's Talmidim citing Rav): They can switch back.

שמואל אמר אין חוזרת חלילה

(g)

Answer #2 (Shmuel): They cannot switch back.

מתניתא פליגא על שמואל שלהן מותרין לו ולהם (שביטל) [צ"ל לא בשביטל להם - שערי תורת ארץ ישראל] רשותו. והתנינן נתנו לו רשותן הוא מותר והן אסורין

(h)

Question: Our Mishnah opposes Shmuel! It teaches that their [houses] are permitted to him and to them. Is this not when he was Mevatel his Reshus to them?! [And the Seifa teaches that later,] if they gave their Reshus to him, he is permitted and they are forbidden!

פתר לה לצדדין היא [דף לט עמוד ב] מתניתא

(i)

Answer: He explains our Mishnah to discuss different cases [in the Reisha and Seifa].
