What is the word "Meihem" referring to?
Ramban #1: It refers to all the above-mentioned Tamei species - to Beheimah, Sheretz and Chayah. 1
Ramban #2 (citing Chagigah, 11a): We learn from "Meihem be'Mosam" 2 that the Shi'ur Tum'ah of a dead Sheretz (of the eight species of Tamei Sheratzim) is a ke'Adashah. 3
Despite the fact that "bahem be'Mosam" in the previous Pasuk refers specifically to Sheratzim (See Ramban).
Chagigah, 11a: Seeing as in the previous Pasuk, the Torah wrote "Bahem" implying that only a complete Sheretz is Tamei. We therefore Darshen "Meihem" like "Bahem", and the smallest size Sheretz (a snail) when formed is the size of a lentil.
The size of a lentil, and not a k'Zayis, like other Neveilos.
How will we reconcile "Meihem" implying even part of a Sheretz) in this Pasuk with "Bahem" - in the previous Pasuk (implying the entire Sheretz)?
Refer to 11:32:1:2**.
Nidah, 56a: The current Pasuk is speaking where the Sheretz is still moist, the previous one, where it has dried. 1
See Torah Temimah, note 92.
Why does the Torah specify "wooden vessels"?
Rashbam: To preclude stone vessels and vessels made of earth from the realm of Tum'ah.
Seeing as the Torah will specificaly state "mi'Nivlasam" (in Pasuk 35), why does it insert the word "be'Mosam" here?
Chulin, 74a: To extrapolate 'Misah Osah Nipul, ve'Ein Shechitah Osah Nipul' ? 'Death renders a loose limb detached (in which case it is Metamei because of Eiver min ha'Chai and not because of Eiver min ha'Neveilah), 1 but not Shechitah (in which case the limb is still considered atached and is not Metamei at all)'.
See Torah Temimah, note 95.
What are the implications of the word "mi'Kol K'li Eitz"?
Sifra: "Kol" comes to include a wooden table, a tablet a Dulf'ki (a drinking table) and a lamp in the current Din of Tum'ah, wheresas the 'Mem' comes to preclude a ladder, a Kolev (a post on which butchers hang meat) and a Nechusah (a large container that contains Keilim). 1
See Torah Temimah, note 96 & 97.
Why does the Torah insert the word "O Beged"?
Shabbos, 27a: To incorporate a Beged of wool or linen 1 that measures only three by three fingerbreadths in the Din of Tum'ah and a Beged of leather or sackcloth 2 that measures three by three Tefachim.
Shabbos, 43b: To include woven cloth in the Din of Tum'ah, irrespective of its (small) size. 3
In which regard is the Torah comparing Or to Beged ("O Beged O Or")?
Sifra: Just as wool and linen ("Beged") grows on land, so too, is only leather that is manufactured from a land-creature subject to Tum'ah, but not if it is manufactured from a sea-creature.
Why does the Torah insert the word "O Sak"?
Shabbos, 64a #1: To include a breast-strap and a band with which one fastens the saddle around the donkey's stomach in the current Din of Tum'ah. 1
Shabbos, 64a #2: To include a garment that is made from the tail of a horse or of a cow in the current Din of Tum'ah.
Shabbos, Ibid: But not (measuring) ropes and cords, since they are not spun and woven like 'Sak'.
Seeing as wooden vessels are not similar to a sack, why does the Torah compare them by placing them in the same Pasuk?
Chagigah, 26b: To compare wooden vessels to a sack, which is moved both full and empty ? to preclude wooden vessels that are made to remain in one place because they are too heavy to carry full, from the realm of Tum?ah. 1
To preclude vessels that hold more than forty Se'ah of liquid - See Torah Temimah, note 108 - which are too heavy to carry.
Why does the Torah insert the word "ve'Taher" after "ve'Tamei ad ha'Erev"?
Rashi: To teach us that after one Tovels, 1 he remains Tamei for Terumah until nightfall, at which point he becomes Tahor for Terumah.
Ramban and Moshav Zekenim: And is Tahor to eat Chulin and Ma'aser Sheini ? though Chulin may be eaten be'Tum'ah and does not require Tevilah (Ramban and Moshav Zekenim).
