The ashes from cleaning the inner altar and the lamp-stand -- one does not benefit from them, nor is one liable for sacrilege regarding them. Granted, for the outer altar, since it is written "and he shall place it beside the altar." But the inner altar -- from where do we learn it? Rabbi Eleazar said: Scripture says, "and he shall remove its crop"; if it is not needed for the matter of the outer altar, apply it to the matter of the inner altar. Say that both this and that refer to the outer altar? If so, let Scripture say "beside the altar"; what is "the ashes"? Even the inner altar. The lamp-stand -- from where do we learn it? "The ashes of the ashes" [the doubled expression includes it].
The Ashes of the Inner Altar and the Lamp-Stand
Yalkut Shimoni on Torah 446:10
דִּשּׁוּן מִזְבֵּחַ הַפְּנִימִי, וְהַמְּנוֹרָה, לֹא נֶהֱנִין וְלֹא מוֹעֲלִין. בִּשְׁלָמָא מִזְּבֵּחַ הַחִיצוֹן דִּכְתִיב "וְשָׂמוֹ אֵצֶל הַמִּזְבֵּחַ". מִזְבֵּחַ הַפְּנִימִי מְנָלַן, אָמַר רַבִּי אֶלְעָזָר, אָמַר קְרָא, וְהֵסִיר אֶת מֻרְאָתוֹ, אִם אֵינוֹ עִנְיָן לְמִזְבֵּחַ הַחִיצוֹן תְּנֵהוּ עִנְיָן לְמִזְבֵּחַ הַפְּנִימִי. אֵימָא אִידִי וְאִידִי בְּמִזְבֵּחַ הַחִיצוֹן, אִם כֵּן לֵימָא קְרָא אֵצֶל הַמִּזְבֵּחַ, מַאי הַדֶּשֶׁן, אֲפִלּוּ מִזְבֵּחַ הַפְּנִימִי. מְנוֹרָה מְנָלַן, דֶּשֶׁן הַדָּשֶׁן.
