Mishnah 1
1)
(a)On what condition does the Mishnah declare Tamei three earthenware legs that one arranges on the ground to hold pots for cooking?
(b)Why does the Tana declare them Tahor if the same tripod comprises three metal pegs that one knocks into the ground?
(c)What does he mean when he adds that this applies even if he arranges a place on top for the pots to rest?
1)
(a)The Mishnah declares Tamei three earthenware legs that one arranges on the ground to hold pots for cooking (see Tos. Yom-Tov) - provided they are joined on top with cement (to form a tripod [see also Tos. Yom-Tov]).
(b)If the same tripod comprises three metal pegs that one knocks into the ground, the Tana declares them Tahor - because metal Kelim that are attached to the ground are not subject to Tum'ah.
(c)When he adds that this applies even if he arranged a place on top for the pots to rest, he means - that he widens the top of each peg so that the pot will not slip off (see also Tos. Yom-Tov).
2)
(a)What does the Tana Kama say about two stones that one arranges on the ground to form a Kirah, and which one duly cements?
(b)R. Yehudah declares them Tahor, unless one of two things are done to them; one of them, that he adds a third leg. What is the other?
(c)What if one joins only two of the three legs with cement (See Tos. Yom-Tov & Tiferes Yisrael), but not the third?
(d)Like whom is the Halachah?
2)
(a)The Tana Kama rules that two stones (see Tos. Yom-Tov) that one arranges on the ground to form a Kirah, and which one duly cements - are subject to Tum'ah.
(b)R. Yehudah declares them Tahor, unless one either adds a third leg - or attaches them to the wall.
(c)He concedes however, that if one joins only two of the three legs with cement, but not the third - it is Tahor.
(d)The Halachah - is like the Tana Kama.
Mishnah 2
3)
(a)On what condition does the Mishnah declare Tamei a stone that is placed beside a Tanur, which is the same height as the oven, and on which one places the pot, half on the Tanur and half on it?
(b)What does the Tana say if it serves the same function, but together with ...
1. ... a Kirah or a Kupach?
2. ... another stone, a rock or a wall (in between which one lights a fire to cook the pot)?
(c)Why the difference?
(d)What condition must we add to the case where the pot is placed on two stones?
3)
(a)The Mishnah declares Tamei a stone that is placed besides a Tanur, which is the same height as the oven, and on which one places the pot, half on the Tanur and half on it - provided it is cemented to it (see Tos. Yom-Tov).
(b)If the stone serves the same function, but together with ...
1. ... a Kirah or a Kupach - then the same Halachah will apply, but if it is attached to ...
2. ... another stone, a rock or a wall (in between which one lights a fire to cook the pot) - it is Tahor ...
(c)... because an earthenware oven must be subject to 'Nesitzah' (demolishing), which they are not (see Tiferes Yisrael [Boaz]).
(d)In the case where the pot is placed on two stones - one of them must be fixed with cement, even if the other is not.
4)
(a)What does the above have to do with Kiras ha'Nezirim in Yerushalayim? What was Kiras Nezirim?
(b)Under what condition is a stone subject to Tum'ah?
(c)The Tana now discusses Kiras ha'Tabachim. What is 'Kiras ha'Tabachim'?
(d)What does the Tana rule in a case where one of the stones becomes Tamei?
4)
(a)'Alehah v'al ha'Sela' fits the description of 'Kiras ha'Nezirim' in Yerushalayim - the oven (in the Lishkas ha'Nezirim [see Tos. Yom-Tov]) on which the Nezirim used to cook their Shalmei Nazir.
(b)A stone is subject to Tum'ah - only if it has been covered with cement.
(c)The Tana now discusses Kiras ha'Tabachim - a multi-stoned oven consisting of many (cemented) stones placed next to each other (and joined with cement), with a space in between (as we just described), where butchers used to place there cuts of meat to sell to the public.
(d)In the event that one of the (cemented) stones becomes Tamei - all the remaining ones remain Tahor.
Mishnah 3
5)
(a)The Mishnah now discusses three stones that one combines (see Tos. Yom-Tov) to form two Kirayim. What will be the Din regarding the middle stone ...
1. ... should one of the outer stones become Tamei?
2. ... if the Tahor stone is subsequently removed?
3. ... if the Tamei stone is subsequently removed?
(b)What is the Din in the event that both outer stones become Tamei? What difference will it make whether the middle stone is a large one or a small one?
(c)On what condition does the Tana declare the oven Tamei, even if one removes the middle stone?
(d)And why does it become Tahor if one subsequently returns the middle stone?
(e)After smearing the stone with cement, what will one need to do before the Kirah is once again subject to Tum'ah?
5)
(a)The Mishnah now discusses three stones that one combines (see Tos. Yom-Tov) to form two Kirayim. The middle stone ...
1. ... should one of the outer stones become Tamei - is (theoretically) divided into two (see Tos. Yom-Tov); the half that forms a stove together with the Tamei stone is Tamei, whereas the other half is Tahor (see Tos. Yom-Tov).
2. ... if the Tahor stone is subsequently removed - is completely Tamei.
3. ... if the Tamei stone is subsequently removed - is completely Tahor.
(b)In the event that both outer stones become Tamei, the Tana rules that if the middle stone is a large one - then one counts the space on which one places a pot at either end as part of its respective Kirah, and the remainder of the stone is Tahor; whereas if it is a small one - then it is completely Tamei.
(c)Even if one removes the middle stone, the Tana declares the oven Tamei - if the oven can hold a large pot.
(d)And it becomes Tahor if one subsequently returns the middle stone - because it is as if the Kirah that held the large pot has been broken, and replaced by two new Kiros.
(e)After smearing the stone with cement - one will need to heat it to the point that one boils on it a chicken's egg (as is the case by a new oven), before the Kirah is once again subject to Tum'ah.
Mishnah 4
6)
(a)The Tana discusses a Kirah comprising two stones that became Tamei. What will be the Din if one now places another stone on either side of the Kirah, turning it into three Kiros? What happens to the two inner stones?
(b)What if someone now removes the two Tahor stones?
6)
(a)The Tana discusses a Kirah comprising two stones that became Tamei. If one now places another stone on either side of the Kirah (see Tos. Yom-Tov), turning it into three Kiros - then the inner half of each of the inner stones remains Tamei, whereas the outer half is Tahor.
(b)If someone removes the two Tahor stones - then the two remaining stones become Tamei like they were before.
