Comentário sobre Negaim 3:8
הַבָּתִּים מִטַּמְּאִין בִּשְׁלשָׁה שָׁבוּעוֹת וּבִשְׁלשָׁה סִימָנִים, בִּירַקְרַק וּבַאֲדַמְדַּם וּבְפִשְׂיוֹן. בִּירַקְרַק וּבַאֲדַמְדַּם, בַּתְּחִלָּה, בְּסוֹף שָׁבוּעַ רִאשׁוֹן, בְּסוֹף שָׁבוּעַ שֵׁנִי, בְּסוֹף שָׁבוּעַ שְׁלִישִׁי, לְאַחַר הַפְּטוּר. וּבְפִשְׂיוֹן, בְּסוֹף שָׁבוּעַ רִאשׁוֹן, בְּסוֹף שָׁבוּעַ שֵׁנִי, בְּסוֹף שָׁבוּעַ שְׁלִישִׁי, לְאַחַר הַפְּטוּר. וּמִטַּמְּאִין בִּשְׁלשָׁה שָׁבוּעוֹת, שֶׁהֵן תִּשְׁעָה עָשָׂר יוֹם. אֵין בַּנְּגָעִים פָּחוֹת מִשָּׁבוּעַ אֶחָד, וְלֹא יוֹתֵר עַל שְׁלשָׁה שָׁבוּעוֹת:
As casas [que têm Negaim ] ficam impuras após três semanas ou através de três sinais: verde escuro, vermelho escuro ou expansão. No que diz respeito ao verde profundo e ao vermelho intenso, [eles são impuros] inicialmente, no final da primeira semana, no final da segunda semana, no final da terceira semana, [ou] após a isenção. Em relação à expansão, no final da primeira semana, no final da segunda semana, no final da terceira semana, [ou] após a isenção. E eles são impuros depois de três semanas, que são na verdade dezenove dias. Não há menos de uma semana [de tempo de quarentena] por Negaim e não mais que três semanas.
Bartenura on Mishnah Negaim
English Explanation of Mishnah Negaim
"By a greenish color or by a reddish color," in the beginning, at the end of the first week, at the end of the second week, at the end of the third week, or after they have been pronounced clean.
"Or by a spreading," at the end of the first week, at the end of the second week, at the end of the third week, or after they have been pronounced clean.
They become unclean for three weeks which are nineteen days.
None of the leprosy signs is for less than a week or for more than three weeks.
Section one: A house has a three week period of impurity and not two like most human negaim and negaim found in clothes (see Leviticus 14:35ff). House impurity will be discussed in chapter twelve.
The signs of a house nega are green or red colored spots, or a spreading after the initial nega has been identified.
Sections two-four: Same as in previous mishnayot.
Section five: This is a summary of all of the laws in most of this chapter. The shortest period is for the nega found in a boil or burn (mishnah four) and the longest period is for negaim found in a house.
