Temurah7: 2
יֵשׁ בְּקָדְשֵׁי בֶדֶק הַבַּיִת מַה שֶּׁאֵין בְּקָדְשֵׁי מִזְבֵּחַ, שֶׁסְּתָם הֶקְדֵּשׁוֹת לְבֶדֶק הַבָּיִת. הֶקְדֵּשׁ בֶּדֶק הַבַּיִת חָל עַל הַכֹּל, וּמוֹעֲלִין בְּגִדּוּלֵיהֶן, וְאֵין בָּהֶם הֲנָאָה לַכֹּהֲנִים.
There are [laws pertaining] to items consecrated for Temple upkeep that are not [applicable] to items consecrated to the Altar [as follows]: Unspecified consecrations are [assumed to be] for Temple upkeep, Temple-upkeep sanctity takes effect upon all things, we transgress me’ilah [by benefit- ing] from that which grows from them, and there is in them no benefit for the Kohanim.
Temurah7: 3
אֶחָד קָדְשֵׁי מִזְבֵּחַ וְאֶחָד קָדְשֵׁי בֶדֶק הַבַּיִת — אֵין מְשַׁנִּין אוֹתָן מִקְּדֻשָּׁה לִקְדֻשָּׁה, וּמַקְדִּישִׁין אוֹתָן הֶקְדֵּשׁ עִלּוּי, וּמַחֲרִימִין אוֹתָן. וְאִם מֵתוּ — יִקָּבֵרוּ. רַבִּי שִׁמְעוֹן אוֹמֵר: קָדְשֵׁי בֶדֶק הַבַּיִת, אִם מֵתוּ — יִפָּדוּ.
[Concerning] both Altar consecrations and Temple-upkeep consecrations, we cannot change them from one sanctity to another sanctity. [However,] we may consecrate them with a consecration of appraisal, and we may make them [the object of] a cherem vow. And if they died, they must be buried. R’ Shimon says: [With regard to animals] consecrated for the upkeep of the Temple, if they died, they may be redeemed.
