Reference for Chullin 180:10
מי כתיב על כן לא יאכל המזבח
An objection was raised from the following: The sciatic nerve of a peace-offering<span class="x" onmousemove="('comment',' It is obvious that the Tanna is referring to the nerve of such consecrated meat as was eaten within the Temple precincts; the peace-offering, however, could be eaten anywhere within the city of Jerusalem. Accordingly Rashi prefers to strike out, 'peace-offering' and substitute 'sin-offering or guilt-offering', for the meat of these could only be eaten by the priests within the Sanctuary. If 'peace-offering' is to be retained, Rashi and Tosaf. offer the suggestion that it refers to the eating by the priests either of their own peace-offerings or of the priestly dues of the 'breast and thigh' portions, and these the priests usually ate within the Sanctuary. MS.M. reads: 'Peace-offering or sin-offering or guilt-offering'.');"><sup>6</sup></span>
