Reference for Zevachim 56:4
אדרבה חוץ למקומו הוה ליה לאוקמי בכרת למגמר עון עון לחוץ לזמנו דדמי ליה במקד"ש
Yet say that 'but every one that eateth it shall bear his iniquity' refers to out of bounds, and thus excludes nothar from kareth? - It is logical that nothar must be made to involve kareth, so that the meaning of 'iniquity', where it refers to [the intention of] eating after time, may learned by analogy, since it is similar thereto in respect of Zab.<span class="x" onmousemove="('comment',' Zab is a mnemonic, standing for zeman, (time) and bamah, (high place) . - In both texts, viz., Lev. VII, 18 and Lev. XIX, 8 Scripture states that he who eats it 'shall bear his iniquity'; the meaning of 'iniquity is further clarified in the latter text by the addition, 'and that soul shall be cut off from his people', i.e., kareth. Now, on the present exegesis this latter verse may refer either to nothar or to eating without bounds, while the former text (Lev. VII, 18) definitely refers to the eating of the flesh before it is actually nothar and within bounds, after the illegitimate intention of eating it after time. Now, if the punishment of kareth in Lev. XIX, 8 is made to refer to nothar (owing to the word 'it' it can only refer to one) , then we can argue that 'iniquity' in VII, 18 too means kareth, by analogy with 'iniquity' in Lev. XIX, 8. And the reason for drawing this analogy is that the two are alike in two respects: (i) Both are defects arising through time, nothar being the case where he actually eats the flesh after time, and Lev. VII, 18 refers to the illegitimate intention of eating after time. (ii) Both were forbidden not only in the Temple, but also in the High Places used before the Temple was built. For but for this similarity, the meaning of 'iniquity' in VII, 18 might be deduced from Ex. XXVIII, 38: And Aaron shall bear the iniquity committed in the holy things. There 'iniquity' refers to sacrificing in a state of uncleanness, which is forbidden by a negative injunction, but does not involve kareth, and so if an analogy were drawn with this verse, one would say that in Lev. VII, 18 too there is no kareth. But if Lev. XIX, 8 is made to refer to eating without bounds, this second analogy might indeed be drawn, since it lacks the two points of similarity, (a private sacrifice offered at a high place might be eaten anywhere) and accordingly nothing will indicate that 'iniquity' means kareth. So Rashi. Tosaf. explains that there was already a tradition that the meaning of 'iniquity' must be deduced by drawing an analogy between Lev. VII, 18 and XIX, 8. and not with Ex. XXVIII, 38. But for that very reason it is logical to make Lev. XIX, 8 refer to nothar, so as to justify the analogy through the two points of similarity.');"><sup>3</sup></span>
