Shekalim4: 5
מוֹתַר הַקְּטֹרֶת מֶה הָיוּ עוֹשִׂין בָּהּ? מַפְרִישִׁין [מִמֶּנָּה] שְׂכַר הָאֻמָּנִין, וּמְחַלְּלִין אוֹתָהּ עַל שְׂכַר הָאֻמָּנִין, וְנוֹתְנִין אוֹתָהּ לָאֻמָּנִין בִּשְׂכָרָן, וְחוֹזְרִין וְלוֹקְחִין אוֹתָהּ מִתְּרוּמָה חֲדָשָׁה.  אִם בָּא הֶחָדָשׁ בִּזְמַנּוֹ, לוֹקְחִין אוֹתָהּ מִתְּרוּמָה חֲדָשָׁה; וְאִם לָאו, מִן הַיְשָׁנָה.
What did they do with the remainder of the incense? They would set aside from the terumah [an amount equal to] the arti-sans’ wages, and would redeem the incense with the artisans’ wages. Then they would give the incense to the artisans as their wages and repurchase it [from them] with [funds] from the new terumah.  If the new [shekalim] came in time, they purchase the incense with [funds from] the new terumah; if not, from the old.
