Eruvin 25

ERUVIN 25, sponsored by a generous grant from an anonymous donor. Kollel Iyun Hadaf is indebted to him for his encouragement and support and prays that Hashem will repay him in kind.

1) [line 15] MASNI L'KULA - Rav Shimi taught the *previous* Sugya (about the Karpaf that is bigger than Beis Se'asayim that was not Hukaf l'Dirah) in a lenient form: (a) Rabah and Rava agree that a pole that is at least three by three Tefachim is effective in reducing the size of the Karpaf; they argue when the pole is smaller. (b) Rabah and Rava agree that a partition that is built at least three Tefachim away from a wall of the Karpaf is effective in making the Karpaf Hukaf l'Dirah; they argue when the partition is built less than three Tefachim away from the wall.

2) [line 27] NICHSEI HA'GER
(a) When a Jew dies, his closest relatives inherit his estate (according to the hierarchy established by the Torah as recorded in Bamidbar 27:8-11). Since all of the Jews are related to each other (at least through Yakov Avinu and his sons), every Jew must have at least one heir. A convert, however, may have no heirs (since his non-Jewish relatives do not inherit his estate). When a convert dies without heirs, his estates becomes Hefker (ownerless). first person who takes possession of his belongings becomes their owner.
(b) In order to take possession of the estate of a convert who dies without any heirs, one must make a Ma'aseh Kinyan (a formal Halachically-binding act of possession), as in all cases of taking possession of items that are Hefker. forms of Ma'aseh Kinyan that may be used are: for Metaltelin (movable goods) - (1) Hagbahah, i.e. lifting an item; (2) Meshichah (lit. pulling), i.e. causing an item to move; (3) Chatzer, i.e. bringing the item into his domain; for Mekarka'in (real estate) - (1) Chazakah, i.e. performing an act that is normally performed by an owner.
(c) Examples of Chazakah are Na'al (locking), Gadar (fencing in) and Paratz (making a breach in a fence to create an entrance) or any act that is done to *enhance* the land, such as digging to improve a field and the like (Mishnah Bava Basra 42a).

3) [line 34] YIRMEYAH BIRA'AH - this is the full name of the sage, as opposed to his name and his city (compare RASHI to Gitin 34A DH Yirmeyah Bira'ah and to Megilah 4a DH Bira'ah)

4) [line 35] D'SHADA LIFTA A'PILA D'AR'A D'GER - who plants turnips in a crack in the ground, in a field that belongs to a convert [who died leaving no heirs]

5) [line 36] RAFAK BAH PURSA - he plowed the field a minute amount
6) [line 37] LO KA SHAVACH - he did not increase its value
7) [line 42] ASAS IHI - she came
8) [line 43] D'LO MECHAZKAS K'D'MACHZEKEI INSHEI - you did not take possession of it in a way people normally take possession

9) [line 44] AVIR KIRUYO MEYATRO - the space of the covered area is nevertheless measured together with the uncovered area, making the area larger than Beis Se'asayim

10a) [line 46] ACHSADRA B'VIK'AH - (a) an area in a field that is covered with a roof but is open on all four sides (RASHI); (b) an area in a field that is covered with a roof and is closed on two or three of its sides (TOSFOS)
b) [line 46] BIK'AH - a plain of open fields

11) [line 47] PI TIKRA YORED V'SOSEM (The Edge of a Roof Beam Descends and Encloses)
(a) The Torah requires Mechitzos (partitions) for various Halachos (e.g. for Reshus ha'Yachid of Shabbos and for Sukah). A Mechitzah must be ten Tefachim high and enclose an area of four by four Tefachim.
(b) When an area is covered by a roof, a Halachah l'Moshe mi'Sinai states that the edge "descends and encloses." Even though that side is completely open and has no physical partition. We may consider the area enclosed for Halachic purposes (see Insights to Eruvin 25:3)
(c) Rav and Shmuel argue as to how many of the four partitions of an area may be enclosed by using Pi Tikra (see Insights to Eruvin 25:2).


12) [line 2] D'AVDAH KI URZILA - (a) he built its roof on a slant (RASHI); (b) according to the Girsa D'AVDAH KI *ARSELA* - he made it like a hammock; i.e. it is open on all four sides (TOSFOS DH Hacha)

(a) King Shlomo decreed that transferring objects from a *private* Reshus ha'Yachid to a *public* one is forbidden, unless an Eruv Chatzeiros (lit. a mixing of the courtyard, Rambam Hil. Eruvin 1:6; or fraternization of the courtyard, Eruvin 49a) is created on Friday, before Shabbos begins (Shabbos 14b, Eruvin 21b).
(b) The Tana'im argue as to whether it is permitted to carry from one *public* Reshus ha'Yachid to another *public* Reshus ha'Yachid. Rabanan rule that it is prohibited, while Rebbi Shimon rules that it is permissible (Eruvin 89a).
(c) This argument only applies to utensils that were in a public Reshus ha'Yachid when Shabbos begins. Utensils that were in a house (= private Reshus ha'Yachid) when Shabbos begins and were taken out to a Chatzer (= public Reshus ha'Yachid) on Shabbos through the use of an Eruv Chatzeiros, may not be transferred to another roof, Chatzer or Karpaf.

*14*) [line 6] K'MAN K'REBBI SHIM'ON - Do you, Rav Yosef, mean to ask your question based on the opinion of Rebbi Shimon?

15) [line 10] GIFUFEI - solid edges that remain on both sides of the breach
16) [line 12] BUSTENA - orchard
17) [line 13] GUDA D'APADNA - the wall of a palace or mansion
18) [line 13] ASHISA BARAISA - the outer wall
19) [line 15] (A'GUDA) [A'GUDEI] GAVYASA - on the inner partitions
20) [line 16] MISHUM D'ATU MI'MULA'EI - (a) since you come from a severed (short-lived) family (the house of Eli, whose male members were cursed to die young - see Shmuel I 2:27-35) (RASHI); (b) since you are a great person (ARUCH)

22) [line 16] AMRISU MILEI MULYASA - (a) you say severed words (that have no foundation) (RASHI); (b) you say great (impossible) words (ARUCH)

23) [line 18] AVARNEKA - (a) a large tree which shades a leisure area that contains benches (RASHI); (b) a covered area or room built by kings in the middle of their orchards (RASHI 26a DH l'Hara, citing Teshuvos ha'Ge'onim)
