Reference for Chullin 136:26
אמר ליה רב יהודה לעולא
But since Scripture expressly mentioned the case of the sin-offering namely that if it was taken out of its bounds and also brought in again it is forbidden, it is clear that only in the case of a sin-offering is this so, but i other cases if they got back within their bounds they would be permitted.<span class="x" onmousemove="('comment',' The verse in Lev. X, 18 clearly demonstrates that the flesh of a sin-offering if taken out beyond the Temple precincts is rendered unfit and must be burnt, whether or not it was once again brought into the Temple precincts. Now it must be remembered that the case of the sin-offering is just one of the instances implied in Ex. XXII, 30, so that it need not have been expressly mentioned (v. supra p. 365, n. 6) . The fact that it is stated suggests that in a particular respect it is different from other cases of 'out of bounds', and that is, that in this case even if it were brought back within its bounds it would be of no avail and the flesh would still have to be burnt. On the other hand, in all other eases of this class, the fact that it has been brought in again within bounds would be an effective remedy.');"><sup>14</sup></span>
