Zevachim12: 3
עוֹרוֹת קָדָשִׁים קַלִּים לַבְּעָלִים, וְעוֹרוֹת קָדְשֵׁי קָדָשִׁים לַכֹּהֲנִים. קַל וָחֹמֶר, מָה אִם עוֹלָה, שֶׁלֹּא זָכוּ בִבְשָׂרָהּ, זָכוּ בְעוֹרָהּ; קָדְשֵׁי קָדָשִׁים, שֶׁזָּכוּ בִבְשָׂרָהּ, אֵינוֹ דִין שֶׁיִּזְכּוּ בְעוֹרָהּ! אֵין מִזְבֵּחַ יוֹכִיחַ, שֶׁאֵין לוֹ עוֹר מִכָּל מָקוֹם.
The hides of the offerings of lesser holiness [belong] to the owners [of the offering], while the hides of the most holy offerings [belong] to the Kohanim. [This can be demonstrated by means of] a kal vachomer — if [in the case of] an olah offering, [in] which they do not acquire the right to its meat, [yet] they acquire a right to its hide; [then in the case of] the most holy offerings, [in] which they do acquire the right to its meat, does it not follow that they acquire the right to its hide! The Altar cannot serve as a refutation, since it does not receive the hide at all.
