Mishnah Negaim 14:8: He comes to the guilt-offering, and leans his two hands on it, slaughters it and two priests capture its blood, one in a vessel and one in his hand. The one who captures it in the vessel goes and throws it on the wall of the altar. The one who captures it in his hand goes to the leper. The leper immerses in the chamber of the lepers. He then goes and stands in the Gate of Nikanor. Rabbi Yehuda says he does not require immersion.

בָּא לוֹ אֵצֶל הָאָשָׁם, וְסָמַךְ שְׁתֵּי יָדָיו עָלָיו, וּשְׁחָטוֹ, וְקִבְּלוּ שְׁנֵי כֹהֲנִים אֶת דָּמוֹ, אֶחָד בִּכְלִי, וְאֶחָד בַּיָּד. זֶה שֶׁקִּבֵּל בַּכְּלִי, בָּא וּזְרָקוֹ עַל קִיר הַמִּזְבֵּחַ. וְזֶה שֶׁקִּבֵּל בַּיָּד, בָּא לוֹ אֵצֶל הַמְּצֹרָע. וְהַמְּצֹרָע טָבַל בְּלִשְׁכַּת הַמְּצֹרָעִים. בָּא וְעָמַד בְּשַׁעַר נִקָּנוֹר. רַבִּי יְהוּדָה אוֹמֵר, לֹא הָיָה צָרִיךְ טְבִילָה:

Mishnah Negaim 14:9: He extends his head and [the priest] places the blood on the cartilage of his ear. [He then extends] his hand and he places the blood on the thumb of his hand. [He then extends] his food and he places the blood on the big toe of his foot. Rabbi Yehuda says he would extend all three at once. If he does not have the thumb of a hand, the big toe of a foot, or a right ear, he can never become pure. Rabbi Eliezer says, he can place [the blood] on their places. Rabbi Shimon says if he put it on his left, it is valid.

הִכְנִיס רֹאשׁוֹ, וְנָתַן עַל תְּנוּךְ אָזְנוֹ. יָדוֹ, וְנָתַן עַל בֹּהֶן יָדוֹ. רַגְלוֹ, וְנָתַן עַל בֹּהֶן רַגְלוֹ. רַבִּי יְהוּדָה אוֹמֵר, שְׁלָשְׁתָּם הָיָה מַכְנִיס כְּאֶחָד. אֵין לוֹ בֹּהֶן יָד, בֹּהֶן רֶגֶל, אֹזֶן יְמָנִית, אֵין לוֹ טָהֳרָה עוֹלָמִית. רַבִּי אֱלִיעֶזֶר אוֹמֵר, נוֹתֵן הוּא עַל מְקוֹמָן. רַבִּי שִׁמְעוֹן אוֹמֵר, אִם נָתַן עַל שֶׁל שְׂמֹאל, יָצָא:
