Reference for Zevachim 4:3
אֵלּוּ דְבָרִים שֶׁאֵין חַיָּבִין עֲלֵיהֶם מִשּׁוּם פִּגּוּל. הַקֹּמֶץ, וְהַלְּבוֹנָה, וְהַקְּטֹרֶת, וּמִנְחַת כֹּהֲנִים, וּמִנְחַת כֹּהֵן מָשִׁיחַ, (וּמִנְחַת נְסָכִים), וְהַדָּם, וְהַנְּסָכִים הַבָּאִים בִּפְנֵי עַצְמָן, דִּבְרֵי רַבִּי מֵאִיר. וַחֲכָמִים אוֹמְרִים, אַף הַבָּאִים עִם הַבְּהֵמָה. לֹג שֶׁמֶן שֶׁל מְצֹרָע, רַבִּי שִׁמְעוֹן אוֹמֵר, אֵין חַיָּבִין עָלָיו מִשּׁוּם פִּגּוּל. וְרַבִּי מֵאִיר אוֹמֵר, חַיָּבִין עָלָיו מִשּׁוּם פִּגּוּל, שֶׁדַּם הָאָשָׁם מַתִּירוֹ. וְכֹל שֶׁיֶּשׁ לוֹ מַתִּירִים בֵּין לָאָדָם בֵּין לַמִּזְבֵּחַ, חַיָּבִין עָלָיו מִשּׁוּם פִּגּוּל:
The following things cannot render one liable for <i>Piggul</i>: the <i>Kometz</i> [a handful of the meal offering which the priest takes to put on the altar], and the frankincense [which is placed on a meal offering], and the <i>Ketoret</i> [holy incense offered twice a day on the golden altar inside the Temple], and the priests' meal-offering, and the meal-offering of an anointed priest, and the libation-offering [wine and flour offerings brought with sacrifices], and the blood, and libations brought on their own - [these are] the words of Rabbi Meir. And the Sages say: even those [libations] that come with the animal [sacrifices are not subject to <i>Piggul</i>]. [Regarding] a <i>Log</i> [a biblical unit of liquid measurement] of oil that a <i>Metzora</i> [one rendered severely impure from an unsightly skin disease. Upon recovery and purification he must bring offerings] [brings], Rabbi Shimon says it cannot render one liable for <i>Piggul</i>; but Rabbi Meir says it can render one liable for <i>Piggul</i> since the blood of a <i>Asham</i> [an offering brought to alleviate guilt] [functions as] the <i>Matir</i> [that which enables a sacrifice to fulfill its purpose] for it [the oil], and anything which has <i>Matirim</i>, whether [permitting the item] for people or for the altar, can render one liable for <i>Piggul</i>.
