פֿאַרבונדענע פּסוקים אויף במדבר 18:28

What is Rebbi Jonah’s reason? Because it already became impure when it was prepared by the grape harvest¹³⁹As explained before, this is R. Yose’s argument.. What is the reason of Rebbi Yose? They were pure by biblical standards. You are the one who decided that they be impure¹⁴⁰This is R. Jonah’s argument. There is no biblical impurity for Gentiles; the laws of impurity are uniquely formulated for Jews. The imputation of impurity (permanent and irrevocable) for Gentiles is rabbinical (Babli 36b). The exclusion of Gentiles from the Temple precinct is not because of impurity but because of their being disqualified.. The strength of Rebbi Yose is the following, as Rebbi Yose said in the name of Rebbi Hila¹⁴¹The source of this statement (in another context) is Ḥallah3:2, Note 53. It should be logical that one may (free)¹⁴²This text makes no sense either by itself nor in this context. Ṭevel is produce under the obligation of heave from which heave was not yet taken; it may not be consumed. By all standards a person is not only permitted but obligated to free his ṭevel by separating the heave. The text in Ḥallah correctly reads: “a person may make his ṭevel impure by biblical standards.” The main point of the argument is given there but omitted here. Heave not only must be consumed in purity but it is stated in Num. 18:8 that the priests have a special duty to guard heave from impurity. It follows that this duty does not apply to ṭevel, which therefore may be allowed to become impure; disagreeing with the hypothesis underlying the Mishnah.
The quote here refers to a different subject. Heave given to Aaron in his quality of priest is pure heave for which he can exercise his duty to watch it and consume it in purity. But once produce has incurred even a doubt of impurity it can no longer be consumed by the Cohen; this eliminates not only the duty of guarding it but all rules made to safeguard it. If the rules of purity no longer can be observed there remain no restrictions on harvesting and pressing grapes with a Gentile. his ṭevel as it is written, you should give from it the Eternal’s heave to Aaron the priest¹⁴³Num. 18:27.. You have to give it to Aaron in his quality of priest. But here, since you cannot give it to Aaron the priest in his quality of priest, you may make it impure.
