(a)In discussing whether something that is Ma'ahil over a Meis transmits Tum'ah on to Keilim on the one hand, and protects from Tum'ah on the other, the Mishnah teaches us that there are some things that can achieve both. What are the other three possibilities?

(b)Under which of the four categories does the Tana list Shidah, Teivah u'Migdol (a large crate (see Tos. Yom-Tov), a box or a drawer and a cupboard)?

(c)The list continues with Kaveres ha'Kash and Kaveres ha'Kanim. What is the difference between them?

(d)And it adds the pit of an Alexandrian ship. What purpose does such a pit serve?

1)

(a)In discussing whether something that is Ma'ahil over a Meis transmits Tum'ah on to Keilim on the one hand, and protects from Tum'ah on the other, the Mishnah teaches us that there are some things that can achieve both - some that can bring Tum'ah but not protect from Tum'ah, some that can protect from Tum'ah and not bring Tum'ah, and some that can do neither.

(b)The Tana lists Shidah, Teivah u'Migdol (a large crate [see Tos. Yom-Tov], a box or a drawer and a cupboard) - under the first category (those that both transmit Tum'ah on Keilim and protect from Tum'ah).

(c)The list continues with Kaveres ha'Kash - which is a large bee-hive like box made of stubble, or of willow or palm branches, and 'Kaveres ha'Kanim' - a similar shaped sort of basket made of reeds (see Tiferes Yisrael).

(d)And it adds the pit of an Alexandrian ship - which is used to store water for long journeys.

(b)Why will they otherwise not save Keilim from Tum'ah?

1. ... forty Sa'ah in liquid measure.

2. ... two Kur (which is the equivalent of sixty Sa'ah) in solid measure.

(b)Otherwise, they will not save Keilim from Tum'ah - since they are themselves subject to Tum'ah (see Tos. Yom-Tov).

2. ... Mechtzeles is - a mat woven out of canes.

(c)Mechonos ha'Of - are animal and bird cages (see Tos. Yom-Tov).

5)

(a)On what condition does the Tana include a bird in the list?

(b)According to R. Yochanan ben Nuri, the only food that protects from Tum'ah is - a round cake of figs (which tends to be extremely large) ...

(a)Now the Mishnah presents a new list beginning with the warp stretched on the loom. Which of the four categories is now under discussion?

(b)What does not Mevi Tum'ah mean? What is the case?

10)

(a)The Mishnah now presents a new list beginning with the warp that is stretched on the loom. The category now under discussion is - the one that is Chotzetz before Tum'ah but is not Meivi Tum'ah (see Tos. Yom-Tov).

(b)When the Tana says Not Meivi Tum'ah, he means that - (as opposed to the first category) if the Tum'ah is on one side of the object, it does not transmit Tum'ah to Keilim on the other side.

11)

(a)The Tana adds Chavilei ha'Mitah, ha'Mashpalos and ha'Serigos she'ba'Chalonos. What are Chavilei ha'Mitah?

(c)What does the Tana mean when he says, with reference to vegetables 'Chutz min ha'Yerakos she'Manu'?

(d)And he continues with Kipas ha'Barad. What might this mean (besides a piece of hail)?

12)

(a)The final list begins with seeds and vegetables that are still attached to the ground - incorporating things that neither transmit Tum'ah nor do they protect from Tum'ah ...

(b)... because every item in this list has no permanence (Tiferes Yisrael).

(c)When the Tana says (with reference to vegetables) Chutz min ha'Yerakos she'Manu, he is referring to - the long-lasting vegetables that are listed in the first Mishnah.

(d)And he continues with Kipas ha'Barad, which (besides a piece of hail), might mean - an arched-shaped piece of hail.

13)

(c)ve'ha'Doleg mi'Makom le'Makom ve'ha'Kofetz mi'Makom le'Makom might refer to an animal and a person respectively. Alternatively - they refer to a person (see Tos. Yom-Tov) who is skipping or jumping, respectively.

(d)The third item in this group is - a bird in flight (see Tos. Yom-Tov).

14)

(a)Under which circumstances does the Tana include in the current list ...

(c)The Halachah is - like the Tana Kama (who declares any Keilim in the boathouse, Tamei).

16)

(a)The Mishnah now cites a case where there are two earthenware barrels, each containing half a k'Zayis of Meis, in a room. What is the status of any Keilim in the room?

(b)Under what condition will the barrels remain Tahor?

(c)Why the difference?

(d)What if one of the barrels is subsequently opened?

16)

(a)The Mishnah now cites a case where there are two earthenware barrels, each containing half a k'Zayis of Meis, in a room - in which case, any Keilim in the room are Tamei.

(b)The barrels however, will remain Tahor - provided the lids on both barrels are sealed ...

(c)... because whereas a sealed lid prevents whatever is inside a K'li Cheres from becoming Tamei, it does not prevent Tum'ah that is inside it from escaping.

(d)If one of the barrels is subsequently opened - then it too, becomes Tamei, but not the one that is still sealed.

17)

(a)The Mishnah equates the basic Halachah in the previous case to one where two Chadarim open into the Bayis. What exactly, is the case?

(b)What does the Tana rule there?

(c)Why is that?

17)

(a)The Mishnah equates the basic Halachah in the previous case to one where two Chadarim open into the Bayis. The case is - where the two rooms, each containing half a k'Zayis of Meis, open into the Bayis (which opens into the street), and their doors are all shut.

(b)The Tana rules there that - the Bayis is Tamei, but the rooms remain Tahor ...

(c)... because the two half-k'Zeisim are destined to be removed through the Bayis, but not through the rooms.
