Riferimento su Levitico 7:39

God commanded that during the offering of the burnt sacrifice the priest must wear one garment while burning it and another when carrying out the ashes. (Lev. 7:4) This verse means to teach us proper conduct. The garments which one wears while preparing food for his master must not be worn while filling his beaker.²⁷⁾שבת קי״ד א׳.
