וְנֶחְשַׁ֥ב לָכֶ֖ם תְּרוּמַתְכֶ֑ם כַּדָּגָן֙ מִן־הַגֹּ֔רֶן וְכַֽמְלֵאָ֖ה מִן־הַיָּֽקֶב׃
And the gift which ye set apart shall be reckoned unto you, as though it were the corn of the threshing-floor, and as the fulness of the wine-press.
Mishnah Terumot
They may not take terumah from produce whose processing has been completed for produce whose processing has not been completed, or from produce whose processing has not been completed for produce whose processing has been completed or from produce whose processing has not been completed for other produce whose processing has not been completed. If they did take terumah, their terumah is terumah.
