Zevachim5: 2
פָּרִים הַנִּשְׂרָפִים, וּשְׂעִירִים הַנִּשְׂרָפִים — שְׁחִיטָתָן בַּצָּפוֹן, וְקִבּוּל דָּמָן בִּכְלִי שָׁרֵת בַּצָּפוֹן; וְדָמָן טָעוּן הַזָּיָה עַל הַפָּרֹכֶת, וְעַל מִזְבַּח הַזָּהָב. מַתָּנָה אַחַת מֵהֶן מְעַכֶּבֶת. שְׁיָרֵי הַדָּם הָיָה שׁוֹפֵךְ עַל יְסוֹד מַעֲרָבִי שֶׁל מִזְבֵּחַ הַחִיצוֹן; אִם לֹא נָתַן, לֹא עִכֵּב. אֵלּוּ וְאֵלּוּ נִשְׂרָפִין בְּבֵית הַדֶּשֶׁן.
The bulls that are burned, and the hegoats that are burned — [have] their slaughter in the north, and the reception of their blood in a sacred vessel in the north; and their blood requires sprinkling toward the Curtain, and on the Golden Altar. [The omission of even] one of these applications prevents [atonement]. The remainder of the blood he would pour on the western base of the outer Altar; [but] if he did not apply [it], it does not prevent [atonement]. These and those are burned in the place of the ashes.
