וְאַתָּ֣ה וּבָנֶ֣יךָ אִ֠תְּךָ תִּשְׁמְר֨וּ אֶת־כְּהֻנַּתְכֶ֜ם לְכָל־דְּבַ֧ר הַמִּזְבֵּ֛חַ וּלְמִבֵּ֥ית לַפָּרֹ֖כֶת וַעֲבַדְתֶּ֑ם עֲבֹדַ֣ת מַתָּנָ֗ה אֶתֵּן֙ אֶת־כְּהֻנַּתְכֶ֔ם וְהַזָּ֥ר הַקָּרֵ֖ב יוּמָֽת׃ (ס)
Engkau dan anak-anakmu bersamamu harus menjaga keimaman kalian dalam segala hal yang berkaitan dengan mezbah dan dengan apa yang ada di balik tirai, dan kalian harus melayani. Keimaman kalian Aku berikan sebagai pelayanan yang merupakan karunia, dan orang luar yang mendekat harus dihukum mati.
Tosefta Chagigah (Lieberman)
3:19: R. Neḥemiah asks why everyone is trusted in matters related to purification-water and Holy Things, but not in matters of heave-offering. He suggests it's to prevent individuals from assuming roles restricted for the priesthood, citing Numbers 18:7. He questions whether this restriction extends to heave-offering, heave-offering of tithe, and dough-offering, but concludes these are excluded because they are subject to the knowledge and consent of the Israelites, unlike tasks within the veil.
