(Mishnah): If one vowed from a house, the Aliyah (second story) is permitted. R. Meir says so;

Chachamim say, the Aliyah is included in the house;

If one vowed from the Aliyah, the house is permitted.

(Gemara): R. Meir's words seem correct for a city-dweller (they do not call an Aliyah 'Bayis', but some villagers do - PNEI MOSHE).

(Mishnah): If one vowed from a bed, a Dargash (this is explained bew) is permitted. R. Meir says so;

Chachamim say, Dargash is included in 'bed'.

If one vowed from a Dargash, a bed is permitted.

(Gemara - Beraisa): [A mourner's] Dargash is erect; it is not inverted (only beds are inverted).

R. Shimon ben Elazar says, he removes the straps [on which the leather is tied], and this suffices (he need not invert it).

(R. Yosah citing R. Yehoshua ben Levi): The Halachah follows R. Shimon ben Elazar.

(R. Yakov bar Acha citing R. Isi): A beds whose poles (that support a pole on which a canopy can be spread) go up and down (they can be removed), he removes them, and this suffices (he need not invert it).

Question: What is a bed, and what is a Dargash?

Answer (R. Yirmiyah): Anything in which [the ropes] are interwoven on [the frame] itself is a bed. If they are not interwoven on [the frame] itself (rather, they pass through loops attached to the side boards) is a Dargash.

Question (Mishnah): A [wooden] bed or crib [receives Tum'ah] from when it is rubbed with skin of a fish (to smooth it).

If they are interwoven on top of [the frame] itself, why does he smooth it?! (The ropes cover it!)

Answer: It discusses beds of Kisaraisa, which have holes [in the frame in which the ropes enter, so the frame is not covered].

(Mishnah): If one vowed from a city, he may enter its Techum (the surrounding Mil (about a kilometer) in which one may walk on Shabbos). He is forbidden its Ibur (the surrounding 71 Amos);

However, if one vowed from a house, he is forbidden only from the Agaf (threshold) or further in.

(Gemara) Question: What is the source that the Ibur of a city is like the city?

Answer - Question: It says "va'Yhi bi'Hyos Yehoshua bi'Yericho" - was he in Yericho?! It says "vi'Yricho Sogeres u'Musgeres", and you say so?!

Answer #1 (R. Yudan bar Shalom): He was in its Ibur.

Answer #2 (R. Avun citing R. Acha): He was in Yericho. (This was after they conquered it; the verses are out of order - PNEI MOSHE.)

Question (R. Mana): Does [the question] not argue with R. Yochanan? R. Yochanan said that that vows follow Leshon Bnei Adam! (Why do we need a source that the Ibur is like the city?)

Answer: It is not [so] normal for one to see someone in Fuma (the Ibur of Tiverya - TZAFNAS PANE'ACH), and he will say 'I saw you in Tiverya.' (Therefore, we asked for a source. We explained this based on BEIS AV EH 8:1, cited in Yerushalayim ha'Benuyah.)
