7כָּל הַמְּנָחוֹת שֶׁיָּצַק עֲלֵיהֶן הַשֶּׁמֶן פָּסוּל לַעֲבוֹדָה כְּגוֹן הַזָּר וְכַיּוֹצֵא בּוֹ אוֹ שֶׁבְּלָלָן אוֹ פְּתָתָם אוֹ מְלָחָן כְּשֵׁרוֹת. הִגִּישָׁן אוֹ הֱנִיפָן חוֹזֵר הַכֹּהֵן וּמַגִּישׁ אוֹ מֵנִיף. וְאִם לֹא הִגִּישׁ וְלֹא הֵנִיף הַכֹּהֵן כְּשֵׁרוֹת. שֶׁנֶּאֱמַר (ויקרא ב ב) "וֶהֱבִיאָהּ אֶל בְּנֵי אַהֲרֹן" (ויקרא ב ב) "וְקָמַץ". מִקְּמִיצָה וְאֵילָךְ מִצְוַת כְּהֻנָּה לִמֵּד עַל יְצִיקָה וּבְלִילָה שֶׁכְּשֵׁרָה בְּזָר:
All of the meal-offerings are acceptable even if oil was poured over them by someone who was unacceptable for Temple service, e.g., a non-priest or the like, or such a person mixed [the oil with the meal], broke [wafers] into pieces, or put salt upon them. If [such a person] approached the altar with them or waved them, a priest should approach the altar with them and/or wave them again. If a priest did not approach the altar with them and/or wave them again, they are [nevertheless] acceptable. [This is derived from Leviticus 2:2:] "And he shall bring it to the sons of Aaron and [one] shall take a handful..." From taking the handful and onward, the mitzvah must be performed by a priest. Pouring and mixing [the oil] may be performed by a non-priest.
