The Mishnah (056) states that Terumah is not separated on Yom Tov. We learned that there is a case where one may separate Terumah on Yom Tov; if he originally brought grain in with the intention of making dough, he may eat it on Yom Tov by means of rubbing, yet he will have to separate Terumah. How do we reconcile this with the mishnah?
Resolution: When the Mishnah said that Terumah is not separated on Yom Tov, it meant in general, but it’s true that in our case Terumah would be separated.
059: Beraisa: If he brought in ears of grain in order to process it for dough, he may eat from it in a casual manner and he need not separate Terumah, but if he brought them in with the intention of rubbing them and eating them in that manner, Rebbi requires Terumah to be separated [since it is brought in with that purpose] and Rabbi Yosi b’Rebbi Yehuda does not.
Abayye: Their debate is only with regard to ears of grain, but in the case of peas, everyone agrees that bundles of pea pods already require Terumah separation.Suggestion: Perhaps this is a proof to Abayye: Beraisa: One who has bundles of Tevel [something which Terumah has not been separated from] Tiltan [it grows in a pod like peas, but it is used as a condiment so only a minimal amount is used at a time. Sometimes the pods are also used to flavor foods], can crush the pods and calculate how much seed was inside, and he separates Terumah from the seeds but not from the pods.
So it seems to follow Rabbi Yosi b’Rebbi Yehuda that when it is accepted that only a small amount will be used, Terumah must be separated. And we see that the law of peas [Tiltan] is different from grain.
