너와 네 아들들은 단과 장 안의 모든 일에 대하여 제사장의 직분을 지켜 섬기라 내가 제사장의 직분을 너희에게 선물로 주었은즉 거기 가까이 하는 외인은 죽이울지니라
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.
