And the 139th prohibition is that kohanim are forbidden from eating meat from any sin-offering whose blood is sprinkled inside [the Sanctuary1].

The source of this prohibition is G‑d's statement2 (exalted be He), "Any sin-offering whose blood is brought into the ohel moed to make atonement in the Sanctuary may not be eaten; it must be burned in fire."

One who does eat [from this meat] is punished by lashes.

In the words of the Sifra: "The verse, 'it may not be eaten; it must be burned in fire' teaches you that there is a prohibition to eat anything the Torah requires you to burn."3
