Negaim 13:8 - 13:9

טהור שהכניס ראשו ורובו – for less than one’s head and the majority of one’s body is not considered coming in.

שהכניס ממנה שלש אצבעות על שלש אצבעות – it is considered as if all of the cloak had entered. But not less than this, for less than three [fingerbreadths] by three [fingerbreadths] is not susceptible to receive defilement and is not considered.

וטמאה – as for example, a cloak afflicted with leprosy that an olive’s bulk of it entered into a pure house.

טמאתו – for an analogy is made between leprosy and a corpse. But a leprous cloak that became defiled through oming in, we derive if from Scripture, as it is written (Leviticus 14:55): “for an eruption on a cloth or a house.”/"ולצרעת הבגד והבית", an analogy is made from a cloth to a house, for just as aa house defiles when one enters it, for it is written (Leviticus 14:46): “Whoever enters the house”/"והבא אל הבית וגו' ", even a cloth defiles through entry. From where do we learn that this includes everything as for example warp and woof and hides, the inference teaches us (Leviticus 13:59): "זאת תורת נגע-צרעת בגד הצמר [או הפשתים או השתי או הערב או כל כלי-עור לטהרו או לטמאו]."/ “Such is the procedure for eruptive affections of cloth, [woolen or linen, in warp or in woof, or of any article of skin, for pronouncing it pure or impure.],” an analogy is made between all of them to a cloth, just as a cloth defiles through entry, so all of them defile through entry.

וכליו על כתפו – folded and placed on his shoulder in the manner of a burden [to carry].

וטבעותיו בידיו – placed in the palm of his hand that is not according to the manner of dressing.

הוא והן טמאין מיד – for we call them also with vessels (Leviticus 14:46): “Whoever enters the house [while it is closed up] shall be impure [until evening].”/"והבא אל-הבית...יטמא" .

היה לבוש כליו – that now his vessels ae not impure, other than on account of himself.

והן טהורים עד שישהה בכדי אכילת פרס – as it is written (Leviticus 14:47): “Whoever sleeps in the house must wash his clothes, and whoever eats in the house must wash his clothes.” And it is taught in a Baraita: I have established only eating and sleeping, but from where can I derive that not eating or not sleeping [is included]? The inference comes to teach us, "יכבס את-בגדיו"/he must wash his clothes – is an inclusion (i.e., widening the scope of the Halakha), if so, why does it state (in Leviticus 14:47): "השכב בבית...והאכל בבית"/one who sleeps in the house….and one who eats in the house? To give a measurement to (Leviticus 13:46): "והבא אל-הבית"/whoever enters the house, which does not require washing of clothes until he remains there long enough eats while he is lying down, meaning to say, when he is reclining. And how much is the measurement of eating? In order to eat a piece of bread, which is one-half of a loaf of an Eruv (see Tractate Eruvin 8b and the dispute between Rashi and Maimonides; according to Rabbi Yohanan ben Beroka, a full loaf is six eggs and half of it is three eggs; according to Rabbi Shimon, the loaf is eight eggs and half of it is four eggs; Maimonides decides according to Rabbi Yohanan ben Beroka, whereas Rashi decides like Rabbi Shimon). According to the words of Rashi, they are four eggs, and according to the words of Maimonides they are three eggs.

מיסב ואוכלן בלפתן (sits and eats them with their condiments) – that its measure is less than if he [would] eat them without their condiments, that through the taste of their condiments, he hurries to eat.
