Reference for Gittin 55:15
אלא אמר אביי לא קשיא הא רבי מאיר דלא חייש למיתה הא רבי יהודה דחייש למיתה
Why not oppose two statements regarding <i>terumah</i> itself? For we learn here: IF THE DAUGHTER OF AN ORDINARY ISRAELITE IS MARRIED TO A PRIEST AND HER HUSBAND GOES ABROAD, SHE GOES ON EATING THE <i>TERUMAH</i> DUES ON THE PRESUMPTION THAT HE IS STILL ALIVE. Does not this contradict the following [Baraitha]: 'If a Priest says to his [non-priestly] wife, "Here is thy Get [to come into force] an hour before my death", she is forbidden to eat the <i>terumah</i> immediately'? — R. Adda the son of R. Isaac answered: There the case is different, because he prohibited her to himself one hour before his death.<span class="x" onmousemove="('comment',' But his chance of dying does not enter into consideration.
