바미드바르 (민수기) 5:26

אזכרתה THE MEMORIAL PART THEREOF — i.e. the handful, and it is so called because through its being burnt the meal-offering is brought to remembrance before the Most High God (Sifrei Bamidbar 17; cf. Rashi on Leviticus 2:2 and 24:7).

וְקָמַ֨ץ הַכֹּהֵ֤ן מִן־הַמִּנְחָה֙ אֶת־אַזְכָּ֣רָתָ֔הּ וְהִקְטִ֖יר הַמִּזְבֵּ֑חָה וְאַחַ֛ר יַשְׁקֶ֥ה אֶת־הָאִשָּׁ֖ה אֶת־הַמָּֽיִם׃

and the priest shall take a handful of the offering, the memorial part of it, and burn it on the altar, and afterward shall cause the woman to drink the water.
