That He prohibited the priests from eating the meat of sin-offerings processed inside [the Sanctuary]. And that is His, may He be exalted, saying, "Every sin-offering whose blood is to be brought to the [...] Sanctuary, etc." (Leviticus 6:23). And one who eats of them is lashed. And the language of the [Sifra] (Sifra, Tzav, Chapter 8:7) is, "'It may not be eaten; it must be burned with fire' - anything that involves burning, involves a negative commandment for its eating. (See Parashat Tzav; Mishneh Torah, Sacrificial Procedure 11.)
