Eruvin 91

ERUVIN 91 - has been dedicated to the memory of Dr. Simcha Bekelnitzky (Simcha Gedalya ben Shraga Feibush) of Queens N.Y. by his wife and daughters on his first Yarzeit (7 Av).
Well known in the community for his Chesed and Tzedakah,
he will long be remembered.

(a) King Shlomo decreed that transferring objects from a Reshus ha'Yachid owned by one person or group to a Reshus ha'Yachid owned by another person or group is forbidden, unless an Eruv Chatzeiros is created on Friday, before Shabbos begins (Shabbos 14b, Eruvin 21b).
(b) Besides houses, there are three categories of Reshus ha'Yachid: Gagos (privately owned roofs), Chatzeiros (jointly owned courtyards) and Karpifos (private fenced in areas that are used for storage or corrals, but not lived in). Tana'im argue as to whether it is permitted to carry from one of these types of Reshus ha'Yachid to another, even if they have different owners. Rebbi Meir (Mishnah Eruvin 89a) rules that it is prohibited to transfer between these different types of Reshuyos. Rabanan (ibid., and Gemara 91a) prohibit transferring from a Karpaf to one of the other two, and Rebbi Shimon (ibid.) rules that it is permitted to transfer between these Reshuyos.
(All of these opinions agree that it is prohibited to carry from *houses* to courtyards or Karpifos, or to roofs and houses owned by another person, since houses are used on a very regular basis and are therefore considered separate from all other Reshuyos ha'Yachid. -- Rashi Eruvin 91a DH v'Karpifos)
(c) The above argument only applies to utensils that were in a roof, courtyard, or Karpaf when Shabbos begins. Utensils that were in a house when Shabbos begins and were taken out on Shabbos to a Chatzer through the use of an Eruv Chatzeiros, may not be transferred to one of the other two Reshuyos even according to Rebbi Shimon.

2) [line 13] TEKO'A - a place located near Beis Lechem
3) [line 14] ALONTIS - a towel
4) [line 24] MI LACHSHACH - (a) who told you this (true) Chidush which seems to have been said through prophecy, that the Halachah follows Rebbi Shimon's ruling whether or not they made an Eruv? (RABEINU TAM according to the Maharsha and Maharshal); (b) who told you (Rav) this falsehood that the Halachah follows Rebbi Shimon's ruling only in the case when they did not make an Eruv?! The Halachah follows Rebbi Shimon's ruling whether or not they made an Eruv (RABEINU SHMUEL); (c) according to the Girsa REBBI YOCHANAN MI'LACHSHACH - Rebbi Yochanan who was born from a whisper. He is called by this name because when he was in his mother's womb his mother felt a need to eat on Yom Kippur. Rebbi said to whisper in her ear that it was Yom Kippur. When this was done her pangs of hunger subsided. Rebbi quoted upon the fetus the verse "Before I formed you in the belly I knew you, and before you came out of the womb I sanctified you." (Yirmeyahu 1:5) (Yoma 82b) (TOSFOS)

5) [last line] KUMSA V'SUDRA - a hat and a scarf


6) [line 1] MIRPESES - a common balcony with a ladder by which the residents of a second story go down to the courtyard and out to Reshus ha'Rabim
