Mishnah 1א׳

שְׁנֵי שְׂעִירֵי יוֹם הַכִּפּוּרִים, מִצְוָתָן שֶׁיִּהְיוּ שְׁנֵיהֶן שָׁוִין בְּמַרְאֶה וּבְקוֹמָה וּבְדָמִים וּבִלְקִיחָתָן כְּאֶחָד. וְאַף עַל פִּי שֶׁאֵינָן שָׁוִין, כְּשֵׁרִין. לָקַח אֶחָד הַיּוֹם וְאֶחָד לְמָחָר, כְּשֵׁרִין. מֵת אֶחָד מֵהֶן, אִם עַד שֶׁלֹּא הִגְרִיל מֵת, יִקַּח זוּג לַשֵּׁנִי. וְאִם מִשֶּׁהִגְרִיל מֵת, יָבִיא זוּג אַחֵר וְיַגְרִיל עֲלֵיהֶם בַּתְּחִלָּה, וְיֹאמַר, אִם שֶׁל שֵׁם מֵת, זֶה שֶׁעָלָה עָלָיו הַגּוֹרָל לַשֵּׁם יִתְקַיֵּם תַּחְתָּיו. וְאִם שֶׁל עֲזָאזֵל מֵת, זֶה שֶׁעָלָה עָלָיו הַגּוֹרָל לַעֲזָאזֵל יִתְקַיֵּם תַּחְתָּיו. וְהַשֵּׁנִי יִרְעֶה עַד שֶׁיִּסְתָּאֵב, וְיִמָּכֵר וְיִפְּלוּ דָמָיו לִנְדָבָה, שֶׁאֵין חַטַּאת צִבּוּר מֵתָה. רַבִּי יְהוּדָה אוֹמֵר, תָּמוּת. וְעוֹד אָמַר רַבִּי יְהוּדָה, נִשְׁפַּךְ הַדָּם, יָמוּת הַמִּשְׁתַּלֵּחַ. מֵת הַמִּשְׁתַּלֵּחַ, יִשָּׁפֵךְ הַדָּם:

The two [sacrificial] goats of Yom Kippur, it is a mitzvah that they be equal in appearance, height, value and be bought at the same time. But even if they are not equal, they are kosher. If one was bought one day, and another the next day, they are kosher. If one [of the goats] dies, if it dies before the lots were drawn, a partner for the second should be bought. If it dies after the lots were drawn, then another pair [of goats] should be brought and lots drawn over them as before, and [the one drawing lots] should say, if [the goat that was intended] for Hashem died, "Let the one for which the lot 'for Hashem' is drawn be established in its place." And if [the goat that was intended for] Azazel died, "Let the one for which the lot "for Azazel" is drawn be established in its place." The second [remaining goat] is left to graze until it develops a blemish, and then is sold, and its monetary value [is used to buy] free-will offerings, for we do not leave a communal chattat [sin] offering to die. Rabbi Yehuda says, We leave it to die. Rabbi Yehuda also said, if [the goat for Hashem's] blood spilled [before it could be sprinkled], the goat sent [to Azazel] is left to die [and another pair are brought]. If the goat sent [to Azazel] has died [first], then the blood [of the goat for Hashem] must be poured out [i.e., discarded, and another pair are brought].

Mishnah 2ב׳

בָּא לוֹ אֵצֶל שָׂעִיר הַמִּשְׁתַּלֵּחַ וְסוֹמֵךְ שְׁתֵּי יָדָיו עָלָיו וּמִתְוַדֶּה. וְכָךְ הָיָה אוֹמֵר, אָנָּא הַשֵּׁם, עָווּ פָּשְׁעוּ חָטְאוּ לְפָנֶיךָ עַמְּךָ בֵּית יִשְׂרָאֵל. אָנָּא בַּשֵּׁם, כַּפֶּר נָא לָעֲוֹנוֹת וְלַפְּשָׁעִים וְלַחֲטָאִים, שֶׁעָווּ וְשֶׁפָּשְׁעוּ וְשֶׁחָטְאוּ לְפָנֶיךָ עַמְּךָ בֵּית יִשְׂרָאֵל, כַּכָּתוּב בְּתוֹרַת משֶׁה עַבְדֶּךָ לֵאמֹר (ויקרא טז), כִּי בַיּוֹם הַזֶּה יְכַפֵּר עֲלֵיכֶם לְטַהֵר אֶתְכֶם מִכֹּל חַטֹּאתֵיכֶם לִפְנֵי יְיָ תִּטְהָרוּ. וְהַכֹּהֲנִים וְהָעָם הָעוֹמְדִים בָּעֲזָרָה, כְּשֶׁהָיוּ שׁוֹמְעִים שֵׁם הַמְפֹרָשׁ שֶׁהוּא יוֹצֵא מִפִּי כֹהֵן גָּדוֹל, הָיוּ כּוֹרְעִים וּמִשְׁתַּחֲוִים וְנוֹפְלִים עַל פְּנֵיהֶם, וְאוֹמְרִים, בָּרוּךְ שֵׁם כְּבוֹד מַלְכוּתוֹ לְעוֹלָם וָעֶד:

[The High Priest] would come to the goat for Azazel and place his two hands on it, and confess. And this is what he would say: "Please God, we, Your people the House of Israel, have committed wrongdoing, transgressed, and sinned before You. Please God, please forgive the wrongdoing, transgressions and sins that we, Your people the House of Israel, have committed, transgressed, and sinned before You. As it is written in the Torah of Moses Your servant (Leviticus 16:30), 'On this day, you will be forgiven and cleansed from all your sins—before Hashem you will be cleansed.'" Then, the priests and the people standing in the courtyard, when they heard the explicit Name from the mouth of the High Priest, would bend their knees, bow down and fall on their faces, and they would say, "Blessed be the Honored Name of His Sovereignty forever."
