Reference for Chullin 10:1
הַזְּרוֹעַ וְהַלְּחָיַיִם וְהַקֵּבָה נוֹהֲגִין בָּאָרֶץ וּבְחוּצָה לָאָרֶץ, בִּפְנֵי הַבַּיִת וְשֶׁלֹּא בִפְנֵי הַבַּיִת, בְּחֻלִּין אֲבָל לֹא בְמֻקְדָּשִׁין. שֶׁהָיָה בַדִּין, וּמָה אִם הַחֻלִּין, שֶׁאֵינָן חַיָּבִין בְּחָזֶה וָשׁוֹק, חַיָּבִין בַּמַּתָּנוֹת, קָדָשִׁים שֶׁחַיָּבִין בְּחָזֶה וָשׁוֹק, אֵינוֹ דִין שֶׁחַיָּבִין בַּמַּתָּנוֹת. תַּלְמוּד לוֹמַר (ויקרא ז), וָאֶתֵּן אֹתָם לְאַהֲרֹן הַכֹּהֵן וּלְבָנָיו לְחָק עוֹלָם, אֵין לוֹ אֶלָּא מַה שֶּׁאָמוּר בָּעִנְיָן:
The law concerning the [right] shoulder, the two cheeks, and maw, due as oblation to the priest, is obligatory in and out of the Holy Land, during and after the existence of the Temple, and applies to animals for ordinary use [חולין], but not to those used as consecrated sacrifices. For it might have been concluded [thus], If in respect to animals slaughtered for חולין, to which the precept of giving the breast and foreleg [to the priest] does not apply, it is nevertheless obligatory to give the above mentioned oblations: it would follow, a fortiori, that these oblations ought also to be given in respect to consecrated sacrifices which are subject to the gift of the breast and foreleg; but it is written [Leviticus 7:34], "[For the wave-breast, and fore-leg, &c.] and have given them to Aaron the priest and his sons by a statute for ever." Hence we are taught, that the priest obtains only what is specified in the text [viz., the breast, &c.].
