(a)The Mishnah discusses a Migdal she'Hu ba'Avir which has Keilim be'Avyo. What is the meaning of ...
1. ... Migdal she'Hu ba'Avir?
2. ... Keilim be'Avyo'?
(b)Why does the Tana rule that if there is a k'Zayis Meis in the cupboard, the Keilim in the cavities are Tahor, and vice-versa?
(c)R. Yossi says Mechtzah le'Mechtzah. What does that mean?
1)
(a)The Mishnah discusses a ...
1. ... Migdal (see Tos. Yom-Yov) she'Hu ba'Avir - a cupboard that is in the open (i.e. in one's back yard) and ...
2. ... Keilim be'Avyo - Keilim lying in cavities that on both sides of the walls of the cupboard.
(b)The Tana rules that if there is a k'Zayis Meis in the cupboard, the Keilim in the cavities are Tahor (see Tos. Yom-Yov) and vice-versa - because he is speaking where the cavities are less than a square Tefach, in which case they cannot transmit the Tum'ah to the other side.
(c)R. Yossi says Mechtzah le'Mechtzah - we divide the cavity in two, the inner half is considered as being part of the cupboard, the outer half, part of the room (see Tos. Yom-Yov).
2)
(a)What does the Mishnah rule, in a case where the cupboard, whose door is shut, is under a roof, and the Tum'ah is ...
1. ... in the cupboard (vis-a-vis Keilim that are in the room)?
2. ... in the room (vis-a-vis Keilim that are in the cupboard)?
(b)What is the reasoning behind this dual ruling?
(c)If the Tum'ah is in the house, on what conditions do Keilim that are perched on top of the cupboard, between the cupboard and the wall or that are lying underneath it, remain Tahor?
(d)What is the Din regarding the Keilim in the house, if the Tum'ah is perched on top of the cupboard or is lying underneath it?
2)
(a)The Mishnah rules, in a case where the cupboard whose door is shut (see Tos. Yom-Yov), is under a roof, and the Tum'ah is ...
1. ... in the cupboard that - the Keilim that are in the room are Tamei.
2. ... in the room that - the Keilim that are in the cupboard) - are Tahor ...
(b)... since the Tum'ah is not going to be taken into the cupboard.
(c)If the Tum'ah is in the house, Keilim that are perched on top of the cupboard, between the cupboard and the wall or that are lying underneath it, remain Tahor - provided there is less than a Tefach space between the cupboard and the ceiling, the wall or the floor (see Tos. Yom-Tov).
(d)But if the Tum'ah is perched on top of the cupboard or is lying underneath it - the Keilim in the house are Tamei, because the cupboard does not protect the Tum'ah from being transmitted to the room, since it is bound to be taken out via the room (see Tos. Yom-Tov).

(a)If the cupboard contains cubicles, which measure a square Tefach but whose opening is less, what does the Mishnah say about Keilim that are in the ...
1. ... room if the Tum'ah is lying in the cubicle?
2. ... cubicle if the Tum'ah is lying in the room?
(b)Which principle governs these rulings?
(c)On what grounds does R. Yossi then declare the Keilim in the room Tahor?
3)
(a)If the cupboard contains cubicles, which measure a square Tefach but whose opening is less, the Mishnah rules that Keilim that are in the ...
1. ... room if the Tum'ah is lying in the cubicle - are Tamei.
2. ... cubicle if the Tum'ah is lying in the room - are Tahor ...
(b)... because the Tum'ah is going to be taken from the cupboard into the house, but not vice-versa.
(c)R. Yossi nevertheless declares the Keilim in the room Tahor - because it is possible to cut the piece of Meis in two and carry it out in halves or to burn it in its place (see Tos. Yom-Tov).
Mishnah 3
4)
(a)What does the Mishnah say in a case where the cupboard is placed in the doorway facing outwards, and the Tum'ah is ...
1. ... in the cupboard?
2. ... in the house? Why is that?
(b)The Tana now discusses the cupboard's Muchni (in the same case). What is a Muchni? Where is it placed?
(c)What does the Tana say (vis-a-vis the status of the Keilim in the room) there where the Tum'ah is lying in a cavity in the wheel, which is underneath the ceiling, and which ...
1. ... has a Posei'ach Tefah?
2. ... does not have a Posei'ach Tefach?
(d)Two other conditions are required for the Keilim in the room to remain Tahor. One of them is that the wheel is not detachable. What is the other (concerning the size of the cupboard)?
(e)Why is that?
4)
(a)The Mishnah rules in a case where the cupboard is placed in the doorway facing outwards, and the Tum'ah is ...
1. ... in the cupboard that - the house is Tahor.
2. ... in the house that - the cupboard is Tamei.
(b)The Tana now discusses the cupboard's Muchni (in the same case) - a wheel (used to transport the cupboard) that protrudes three Tefachim into the room.
(c)And he rules that if the Tum'ah is lying in a cavity in the wheel, which is underneath the ceiling, and ...
1. ... has a Posei'ach Tefach - the Keilim in the room are Tahor.
2. ... does not have a Posei'ach Tefach - they are Tamei.
(d)Two other conditions are required for the Keilim in the room to remain Tahor; that the wheel is not detachable and that - the cupboard is sufficiently large to hold forty Sa'ah of liquid (or two Kur of solid ...
(e)... because otherwise - like any other K'li, it is subject to Tum'ah, but is not Chotzetz before it.
