(Mishnah): One may stand in Reshus ha'Yachid and move things in Reshus ha'Rabim, or vice-versa, as long as he is not Motzi (take something in Reshus ha'Rabim) outside of four Amos.

One may not stand in Reshus ha'Yachid and urinate to Reshus ha'Rabim, or from Reshus ha'Rabim to Reshus ha'Yachid. Similarly, one may not spit from Reshus to Reshus;

R. Yehudah says, once saliva is gathered in his mouth, he may not walk four Amos [in Reshus ha'Rabim] before spitting it out.

(Gemara): This is not unanimous, that one may stand in Reshus ha'Yachid and move things in Reshus ha'Rabim, or vice-versa, as long as he is not Motzi outside of four Amos.

Source (Rav): A Mishnah (below, 9) says so (that it is not unanimous). One may not stand in Reshus ha'Yachid and unlock in Reshus ha'Rabim, or stand in Reshus ha'Rabim and unlock in Reshus ha'Yachid, unless he made a Mechitzah 10 Tefachim tall. R. Meir says so. (We explained this like PNEI MOSHE.)

(Rav and R. Yochanan): [R. Yehudah] discusses phlegm [but not regular saliva].

Support: If you would not say so, R. Yehudah [would contradict] what he said elsewhere, that Mashkeh Tofe'ach (wet enough to wet something else) is connected. (Regular saliva in the mouth is not considered detached.)

Not only [is it forbidden] to stand in Reshus ha'Yachid and urinate to Reshus ha'Rabim - rather, even if he stands in Reshus ha'Rabim urinates in Reshus ha'Rabim and it flows down to Reshus ha'Yachid, it is forbidden.

(R. Yosi bei R. Bun): Not only [is it forbidden] to stand in Reshus ha'Rabim and urinate to Reshus ha'Yachid - rather, even if he stands in Reshus ha'Yachid and urinates in Reshus ha'Yachid and it flows down to Reshus ha'Rabim, it is forbidden.

Inference (R. Yosa): This teaches that a pipe standing in Reshus ha'Rabim, 10 tall and four wide (it is Reshus ha'Yachid), one may not pour into it water that will flow and descend [to Reshus ha'Rabim].

(Mishnah): One may not stand in Reshus ha'Yachid and [stick his mouth out and] drink in Reshus ha'Rabim, or vice-versa [lest he bring the cup into the Reshus in which he stands, for which he would be liable], unless Rosho v'Rubo are in the same Reshus that he drinks from;

The same applies to a winepress.

One may be Kolet (catch in mid-air) water dripping from a gutter pipe within 10 Tefachim of the ground;

One may drink from a Tzinor (a pipe that sticks out from the roof) in any case (even Metzaref, i.e. his mouth is next to it).

(Gemara): Granted, One may not stand in Reshus ha'Rabim and [stick his head out and] drink in Reshus ha'Yachid (his mouth is in Reshus ha'Yachid, even if it is above 10).

Question: [Why is it forbidden to stand] in Reshus ha'Yachid and drink in Reshus ha'Rabim? Is his mouth not above 10 Tefachim [which is Mekom Petur]?! (We explained this like MEICHAL HA'MAYIM.)

Answer: Here is different, for [the water] descends [into his innards, which are below 10].

Note: An average person is three Amos tall (some say that this is until the shoulder, and some say until the head). One's belt is above half his height. The stomach is above 10! Perhaps since often it is below 10, e.g. a short man, a young man (e.g. 13 years old), a woman, one who is sitting... it is reasonable to forbid in every case.

(Beraisa): If Rosho v'Rubo (the head and majority) of a camel are inside, one may force-feed it inside. If [Rosho v'Rubo] are outside, one may force-feed it outside.

Question: Granted, when [Rosho v'Rubo] are inside, one may force-feed it [only] inside. When they are outside, why may one force-feed it [only] outside? Is its mouth not above 10 Tefachim (Mekom Petur)?!

Answer: R. Yosi bei R. Bun reverses the teaching. (If Rosho v'Rubo are inside, one may force-feed it food inside when he stands outside. We are not concerned lest he take the food to where he is. If Rosho v'Rubo are outside, one may force-feed when he is inside.)

(R. Chiyah): "The same applies to a winepress'' [in our Mishnah] refers to Ma'aser. (Just like one may not drink in a different Reshus than he stands in, unless he enters Rosho v'Rubo there, one may not drink from a winepress without tithing unless he enters Rosho v'Rubo there. We explained this like PNEI MEIR.)

Question: (Why does our Mishnah permit to be Kolet from a Mazchilah, i.e. gutter-pipe, below 10? Presumably, it is less than three wide. If so, it is Reshus ha'Yachid, like the roof!) Did not R. Yakov bar Acha say in the name of R. Chaninah that within three Tefachim of a Mechitzah are like the Mechitzah?!

Answer: The case is, it is more than three from the roof, but it is not four wide.

Note: There is an implied question. Even if it were four by four, it is not Reshus ha'Yachid, for goats can penetrate underneath!

Answer: If one inserted a stick and it is surrounded by walls (it is in Reshus ha'Yachid) and he threw from Reshus ha'Rabim to it - R. Yitzchak ben Elazar says that this depends on the argument [of R. Yosi b'Ribi Yehudah and Rabanan. R. Yosi b'Ribi Yehudah holds that it is Reshus ha'Yachid even if goats can penetrate underneath.]

Question (R. Yudan - Mishnah): If [a woman] was standing on top of the roof, and [her husband] threw [a Get] to her, once it reaches the airspace of the roof, she is divorced [according to everyone. Even Rabanan agree that the air above Reshus ha'Yachid is like Reshus ha'Yachid!]

Answer (R. Eliezer): One Mishnah discusses a roof with a railing around it. [She is divorced] after [the Get] descended to the airspace within the railing;

And if it does not have a railing, it must descend within three [Tefachim] of the roof, for within three of the roof are like the roof. (However, above the railing and above three, Rabanan say that she is not divorced.)

Note: There is an implied question. If the Mazchilah is not four wide, why is it permitted only below 10?

Answer #1 (Rav Yehudah): [Our Mishnah] is like R. Meir, who says "you view the wall as if it were carved out'' (to complete the pipe to a Shi'ur of four by four. Above 10 it is Reshus ha'Yachid, so we forbid Kolet, for it is like Motzi from Reshus ha'Yachid to Reshus ha'Rabim.)

Answer #2 (R. Yakov bar Acha citing R. Lazar): It is like everyone. The case is, [the Mazchilah] slopes 10 [Tefachim] amidst three [Amos, near the ground, and it is four wide, so it is Reshus ha'Yachid].

Objection (R. Yosi): If it slopes 10 amidst three, it is like the roof! (Why is it permitted below 10?)

Answer: There (regarding Get), which need not rest (like we find regarding a Get thrown over the roof, if it is thrown onto an incline, it is not valid) until it rests. Here (Shabbos) that we require Hanachah, all the more so [we permit water falling from a Mazchilah, for it did not have Hanachah]!

Question (R. Chaninah, to R. Mana): [If so, also above 10 should be permitted,] for there was no Hanachah!

Answer (R. Mana): Since it is four wide, even if there was no Hanachah, [we are stringent to consider it] as if there was Hanachah. (We explained the entire Sugya like MEICHAL HA'MAYIM.)

(Mishnah): If a pit is in Reshus ha'Rabim and its Chulyah is 10 Tefachim tall, a window over it may draw water from it on Shabbos;

If a wasteheap in Reshus ha'Rabim is 10 Tefachim tall, a window over it may spill wastewater onto it on Shabbos.

(Gemara) Question: Do you not view depth like height?! (The pit should be Reshus ha'Yachid even if its Chulyah is not 10 tall!)

Answer: The case is, the opening of the pit is not four wide [so the Chulyah must be 10 to complete the Shi'ur of four].

Question: This is if [the window] is very close to the pit. If it is distanced [four Tefachim, what is the law]?

Answer: Rav and Shmuel - one of them said that he puts a plank [from the window to the pit, so it will all be airspace above Reshus ha'Yachid], and one said that he inserts a stick [in between, to stop people from passing through]. We do not know who said who said this.

Inference: Since Shmuel taught that above 10 [over Reshus ha'Rabim, carrying there] is Shevus, this shows that he said that he puts a plank.

If there were two windows [distanced from the pit], two Amora'im [argued about this]. One said [that each makes a Mechitzah] 10 tall [from his window to the pit], and the other said that he [makes a plank] four [wide].

Question (the one who said 10, against the one who said four): [According to you,] does it not turn out that two Reshuyos use one Reshus?!

Answer: Reshus ha'Rabim [separates them, and] prevents [them from being considered two Reshuyos using one Reshus - PNEI MEIR. Perhaps the text should say "Mavdeles''- PF.]
