וְהֵרִ֨ים הַכֹּהֵ֤ן מִן־הַמִּנְחָה֙ אֶת־אַזְכָּ֣רָתָ֔הּ וְהִקְטִ֖יר הַמִּזְבֵּ֑חָה אִשֵּׁ֛ה רֵ֥יחַ נִיחֹ֖חַ לַיהוָֽה׃
Der Priester hebe von dem Speiseopfer den Duftteil ab und lasse ihn in Dampf aufgehen auf dem Altar, ein Feueropfer des Wohlgeruchs dem Herrn.
Rashi on Leviticus
את אזכרתה ITS MEMORIAL PORTION — this is the “fistful” (קמץ) (cf. Rashi on v. 2).
Siftei Chakhamim
The fistful. [Rashi knows this] because it is written above: “The kohein shall separate from the meal-offering,” and afterwards it is written: “its memorial portion and burn it on the altar...”
Chizkuni
והרים, “the priest will lift off, etc.” just as this procedure mentioned in chapter 6,8 consists of a fistful of the priest’s three middle fingers, קומץ, so this is also what it means here, though the Torah does not mentions a quantity.
