Text Excerpt
הא רבי, הא רבי יוסי ברבי יהודה. דתניא: הכניס שבלין לעשות מהן עיסה — אוכל מהן עראי, ופטור.
This source, the baraita, is in accordance with the opinion of R' Yehuda HaNasi, who holds that one must separate teruma from kernels of grain on the stalk, and one may separate terumot on a Festival. That source, the Mishnah, is in accordance with the opinion of R' Yosei, son of R' Yehuda, who maintains that there is no need to separate teruma from kernels of grain on the stalk, as it is taught in a baraita: If one brought inside his house stalks of grain in order to grind them into flour and to make dough from them, he may eat from them, as a snack, before they are ground, and he is exempt from teruma. Provided that the grain has not yet been fully processed, the obligation to separate teruma does not apply. The rabbis decreed that such produce may only be consumed casually and not as part of a regular meal.
למוללן במלילות — רבי מחייב ורבי יוסי ברבי יהודה פוטר.
However, if from the outset one brought in the stalks of grain not to grind them but to husk the kernels and eat them a little at a time, R' Yehuda HaNasi obligates him to separate teruma from them and prohibits him from partaking of the grain until he has done so. And R' Yosei, son of R' Yehuda, exempts him from the obligation of teruma. He maintains that not even this intention renders one obligated to separate teruma, as the obligation for teruma applies only to fully processed grain.
ולרבי יוסי ברבי יהודה נמי משכחת לה — כגון שהכניס שבלין לעשות מהן עיסה, ונמלך עליהן למוללן ביום טוב, דטבלא ביומיה!
The Talmud challenges this: And according to the opinion of R' Yosei, son of R' Yehuda, you can also find a case when one must separate teruma from grain that has not been fully processed. How so? For example: if one brought inside his house stalks of grain to make dough from them, thereby rendering himself obligated to separate teruma from them, and he reconsidered and decided to husk them in order to eat the kernels on a Festival. In that case, the prohibition of untithed produce takes effect on that day and one is obligated to separate teruma, only afterward is he permitted to eat the kernels.
