נגעים ג׳Negaim 3

Mishnah 1א׳

הַכֹּל מִטַּמְּאִין בַּנְּגָעִים, חוּץ מִן הַנָּכְרִים וְגֵר תּוֹשָׁב. הַכֹּל כְּשֵׁרִים לִרְאוֹת אֶת הַנְּגָעִים, אֶלָּא שֶׁהַטֻּמְאָה וְהַטָּהֳרָה בִידֵי כֹהֵן. אוֹמְרִים לוֹ אֱמֹר טָמֵא, וְהוּא אוֹמֵר טָמֵא. אֱמֹר טָהוֹר, וְהוּא אוֹמֵר טָהוֹר. אֵין רוֹאִים שְׁנֵי נְגָעִים כְּאֶחָד, בֵּין בְּאִישׁ אֶחָד וּבֵין בִּשְׁנֵי אֲנָשִׁים, אֶלָּא רוֹאֶה אֶת הָאֶחָד וּמַסְגִּירוֹ וּמַחְלִיטוֹ וּפוֹטְרוֹ, וְחוֹזֵר לַשֵּׁנִי. אֵין מַסְגִּירִין אֶת הַמֻּסְגָּר וְלֹא מַחְלִיטִין אֶת הַמֻּחְלָט. אֵין מַסְגִּירִין אֶת הַמֻּחְלָט, וְלֹא מַחְלִיטִין אֶת הַמֻּסְגָּר. אֲבָל בַּתְּחִלָּה, בְּסוֹף שָׁבוּעַ, הַמַּסְגִּיר מַסְגִּיר, וְהַמַּחְלִיט מַחְלִיט, מַסְגִּיר וּפוֹטֵר, מַחְלִיט וּפוֹטֵר:

Everyone is made impure by Negaim except for the non-Jews and a Ger Toshav [resident non-Jew who accepted the seven Noahide laws]. Everyone is valid for examining Negaim, except that the impurity and the purity [of the examined person] is in the hands of a priest. They say to him [i.e. the priest], "Say [he is] impure," and he says, "Impure." [They say to him], "Say [he is] pure," and he says, "Pure." One may not examine two Negaim at once, whether on one person or whether on two people, but one must examine the first and quarantine it and decide upon it [whether it is impure] and exempt it, and [then] return to the second. One does not quarantine someone who has already been quarantined [if a new Nega appeared] and one does not decide upon someone who has already been decided upon. One does not quarantine someone who has already been decided upon, and one do not decide upon someone who has already been quarantined. But in the beginning [or] at the end of the week [of quarantine or impurity], he who quarantines [for the first Nega may quarantine [for the second], and he who decides [for the first] may decide [for the second], quarantine [the first] and exempt [the second], decide upon [the first] and exempt [the second].

Mishnah 2ב׳

חָתָן שֶׁנִּרְאָה בוֹ נֶגַע, נוֹתְנִין לוֹ שִׁבְעַת יְמֵי הַמִּשְׁתֶּה, לוֹ וּלְבֵיתוֹ וְלִכְסוּתוֹ. וְכֵן בָּרֶגֶל, נוֹתְנִין לוֹ כָל יְמוֹת הָרָגֶל:

A groom upon whom appears a Nega, we give him the seven days of feasting [before examining him]. [This applies] to him, to his house, or to his clothing. Also [if one got a Nega] during a pilgrimage festival, we give him all the days of the pilgrimage festival.
