Reference for Zevachim 8:3
אָשָׁם שֶׁנִּתְעָרֵב בִּשְׁלָמִים, יִרְעוּ עַד שֶׁיִּסְתָּאֲבוּ. רַבִּי שִׁמְעוֹן אוֹמֵר, שְׁנֵיהֶם יִשָּׁחֲטוּ בַצָּפוֹן, וְיֵאָכְלוּ כֶחָמוּר שֶׁבָּהֶן. אָמְרוּ לוֹ, אֵין מְבִיאִין קָדָשִׁים לְבֵית הַפְּסוּל. נִתְעָרְבוּ חֲתִיכוֹת בַּחֲתִיכוֹת, קָדְשֵׁי קָדָשִׁים בְּקָדָשִׁים קַלִּים, הַנֶּאֱכָלִין לְיוֹם אֶחָד בַּנֶּאֱכָלִים לִשְׁנֵי יָמִים, יֵאָכְלוּ כֶחָמוּר שֶׁבָּהֶן:
[If] an <i>Asham</i> became mixed up with a <i>Shelamim</i> [offerings whose various parts are consumed by its owners, the <i>Kohanim</i> and the fire on the altar], they are left to graze until they become blemished. Rabbi Shimon says: Both of them are slaughtered on the north [side of the altar] and they are eaten according to [the rules governing] the more stringent of the two. They [the Sages] said to him: We do not cause consecrated animals to become invalid. If pieces of meat became mixed up with other pieces of meat, the meat of the sacrifices of <i>Kodshai Kodashim</i> [sacrifices of the highest degree of sanctity. They may be slaughtered only on the north-west corner of the altar, and consumed only within the Temple compound by male priests, or burnt entirely] with the meat of <i>Kodashim Kalim</i> [sacrifices of a lesser degree of sanctity. They may be slaughtered anywhere in the Temple courtyard and consumed by most anyone, anywhere in Jerusalem], [or those] which are eaten over one day with those which are eaten over two days - [all] are eaten according to [the rules governing] the more stringent of the two.
