"The priests" (Leviticus 1:8) — this includes even bald priests; these are the words of Rabbi Yehudah. "And they shall arrange the pieces" — what does Scripture teach by saying "the head and the fat," and so on, as above? One might think that a person who freely vows a burnt offering should bring wood and fire along with it; therefore Scripture says, "upon the wood that is upon the altar" (Leviticus 1:8). Just as the altar is from the public, so too the wood and the fire are from the public — these are the words of Rabbi Elazar son of Rabbi Shimon. Rabbi says: Just as the altar is something no layman has made use of, so too the wood and the fire must be such as no layman has made use of.
The Wood and the Fire of the Altar Belong to the Public
Yalkut Shimoni on Torah 444:6
הַכֹּהֲנִים, לְרַבּוֹת אֶת הַקֵּרְחִים, דִּבְרֵי רַבִּי יְהוּדָה. וְעָרְכוּ אֵת הַנְּתָחִים, מַה תַּלְמוּד לוֹמַר "אֶת הָרֹאשׁ וְאֶת הַפָּדֶר" וְכוּ' כְּדִלְעֵיל. יָכוֹל הַמִּתְנַדֵּב עוֹלָה יְהֵא מֵבִיא עֵצִים וְאֵשׁ עִמָּהּ תַּלְמוּד לוֹמַר "עַל הָעֵצִים אֲשֶׁר עַל הַמִּזְבֵּחַ", מַה מִּזְבֵּחַ מִשֶּׁל צִבּוּר אַף עֵצִים וְאֵשׁ מִשֶּׁל צִבּוּר דִּבְרֵי רַבִּי אֶלְעָזָר בְּרַבִּי שִׁמְעוֹן, רַבִּי אוֹמֵר מַה מִּזְבֵּחַ שֶׁלֹּא נִשְׁתַּמֵּשׁ בּוֹ הֶדְיוֹט, אַף עֵצִים וְאֵשׁ שֶׁלֹּא נִשְׁתַּמֵּשׁ בָּהֶן הֶדְיוֹט.
