תלמוד על תרומות 3:1

There⁴⁸Mishnah Ṭevul Yom 4:6., we have stated: “If somebody gives heave from a wine cistern and says: ‘This should be heave on condition that it be removed whole’, it means whole from breakage and whole from spillage⁴⁹If the amphora containing the heave wine breaks or some of its contents are spilled before the amphora is safely removed from the cistern, the wine that flows back into the cistern is ṭevel in breakage and profane in spillage, never heave, and does not make the remaining wine dema‘ (cf. Demay Chapter 1, Note 175, Chapter 4, Note 25; Terumot Chapter 5). Dema‘ wine is almost worthless. but not from impurity. Rebbi Simeon says, also from impurity.” Rebbi Yose ben Ḥanina said, this Mishnah speaks of the impurity of ṭevul yom⁵⁰A person freed from impurity by immersion in water who will become pure at sundown. His touch does not make impure but it invalidates heave and sacrifices, cf. Demay Chapter 6, Note 136.. Rebbi Ila said, since ṭevulê yom may be present around wine presses. Rebbi Yose said, a ṭevul yom has no touch for ṭevel⁵¹The touch of a ṭevul yom invalidates heave but not ṭevel and certainly not profane wine. Therefore, a ṭevul yom may work in a winery producing pure wine and R. Simeon is right when he assumes that a reservation concerning the touch of a ṭevul yom is in the mind of the person taking heave, even if this is not consciously expressed. Cf. also Ḥallah 3:2, Note 43..
