2)

(a)The Tana rules that - a round or triangular house - is not subject to Tum'as Nega'im ...

(b)... because the Torah writes twice "be'Kiros ha'Bayis" (see Tos. Yom-Tov), implying that it has to have four walls (and not three, or two or five [see Tos. Yom-Tov]).

(c)... and the same applied to a Nega that appears on ...

1. ... a boat-house ...

2. ... a cabin that is built on the mast of a ship ('Askarya' [see Tos. Yom-Tov]), or ...

3. ... brick - Tahor.

(b)The fourth item on the Tana's list is - earth (see also Tos. Yom-Tov DH 've'Echad be'Afar).

5)

(a)What if the owner brought stones, wood and earth and added them to the building after the Nega had already appeared?

11)

(a)What do we learn from the Pasuk "u'Ba Asher lo ha'Bayis ... ke'Nega Nir'ah li ba'Bayis"?

(b)What if the owner of the house is a Talmid-Chacham and the Kohen, an Am ha'Aretz?

(c)What must the Kohen do when he hears this?

11)

(a)We learn from the Pasuk "u'Ba Asher lo ha'Bayis ... ke'Nega Nir'ah li ba'Bayis" - that when the owner informs the Kohen that his house is stricken, this is what he must say, and not 'Nega Nir'ah li ba'Bayis' ...

12)

(a)R. Shimon objects to R. Yehudah's ruling that even bundles of wood (see Tos. Yom-Tov) and bundles of canes (see Tos. Yom-Tov) must be removed from the house - because there is a good reason for clearing the vessels out of the house (as we shall now see), other than just to keep the owner busy.

(b)It appears that he agrees with R. Meir, who says - that wooden vessels and clothes need not be removed, because even in the event that the Kohen declares the house Tamei, they can easily be Toveled ...

(c)... and the same applies to metal vessels.

13)

(a)According to R. Meir, which vessels must be taken out of the house?

(b)He specifies Pacho and Tifyo. Pacho' means - 'his small earthenware jars'.

(c)Tafyo with a 'Tav'incorporates various kinds of ovens (from the word 'Ofeh'). If it is spelt with a 'Tes' it means - a small earthenware vessel containing liquid which it emits in drops (from the word 'Tif' [a drop]).

14)

(a)R. Meir finally makes two 'Kal va'Chomers'. What does he extrapolate from the fact that Hash-m takes pity on ...

1. ... the money of a Rasha?

2. ... the property of a Rasha?

(b)Why does it refer to the owner as a Rasha?

14)

(a)R. Meir finally makes two 'Kal va'Chomers'. He extrapolates from the fact that Hash-m takes pity on ...

1. ... the money of a Rasha - that Hash-m certainly has pity on his children, and from ...

2. ... the property of a Rasha - that He certainly takes pity on the property and children of a Tzadik.

(b)It refers to the owner as a Rasha - because Nega'im come on a person first and formost as the result of Lashon ha'Ra (see Tos. Yom-Tov).

(a)The Torah writes "ve'Yatza ha'Kohen min ha'Bayis el Pesach ha'Bayis". We learn from ...

2. ... "ve'Yatza ... min ha'Bayis" - that he must leave the house completely and actually step off the threshold (see Tos. Yom-Tov) before shutting the door and declaring the house Tamei.

(b)If at the end of seven days, the Nega has spread - the Kohen removes the stricken stones and takes them to a Tamei location outside the town (see Tos. Yom-Tov Mishnah 7, DH 'el mi'Chutz la'Ir") and dumpss them there.

(c)Then he takes other stones and earth, and replaces the original ones.

1. ... replacing the stones or earth that he has removed with stones or earth from another part of the stricken wall?

2. ... using lime instead of earth to cement the stones?

3. ... replacing one stone with two, or vice-versa?

(b)In fact, the Kohen must replace two stricken stones with two fresh stones. What does he do if three, four or five stones are stricken?

1. ... the plural in the word "ve'Chiltzu es Avanim"?

2. ... the singular in the words've'Afar Acher Yikach ve'Tach es ha'Bayis"?

(c)We learn from the Torah's use of ...

1. ... the plural in the word "ve'Chiltzu es Avanim" - that the 'Rasha's neighbor is obligated to remove the adjoining stones from his side of the wall too, to scrape away the cement (see Tos. Yom-Tov) and to replace them just as the Rasha is.

2. ... the singular in the words've'Afar Acher Yikach ve'Tach es ha'Bayis" - that he is not obligated to cement the fresh stones after replacing the old ones.

(d)The Shi'ur for a Nega that disappears from the wall and later reappears is - that of two G'risin (see Tos. Yom-Tov).
