לימא תיהוי תיובתא דבר פדא דאמר לא פקעה קדושה בכדי
and this is its meaning: If he did not say, 'let this be a peace — offering from now, it remains a burnt-offering after thirty days.<span class="x" onmousemove="('comment',' The text is thus to be reconstructed: If one says, 'Let this ox be a burnt-offering for thirty days, and from now and after thirty days a peace-offering': it is a burnt-offering for the first thirty days, and a peace-offering after that. But if he did not say, 'Let it be a peace-offering from now and after thirty days', but merely, 'let it be a burnt-offering for thirty days; and a peace-offering afterwards'; it remains a burnt-offering after thirty days. In the former case, the sanctity pertaining to the burnt-offering automatically ceases, because that of the peace-offering is potentially concurrent therewith and extends beyond it; but in the latter case, the sanctity cannot automatically cease (Rashi). Ran, Asheri and Tosaf. explain it differently. ');"><sup>3</sup></span>
