Torah Temimah → גִּטִּין ל׳ ב׳ / מְנָחוֹת נ״ד ב׳ · Abba Elazar b. Gimel
English: The verse speaks of two terumos — terumah gedolah and terumat maaser; therefore just as terumah gedolah is taken by estimate, by intent, and generously, so is terumat maaser.
Two terumos; estimate and generous eye.
Terumat maaser follows terumah gedolah in estimation and generous measure.
