Uktzin 3:5-6

Uktzin 3:5

Costus, amomum, select spices, buttercup, asafoetida, pepper and saffron lozenges may be bought with second tithe money but they don’t convey food impurity; this is the opinion of Rabbi Akiva. Rabbi Yochanan ben Nuri asked him, if they can be bought with second tithe money, why shouldn’t they convey food impurity? If they don’t convey food impurity, they shouldn’t be bought with second tithe money.

Uktzin 3:6

Rabbi Akiva says that unripe figs and grapes convey food impurity; Rabbi Yochanan ben Nuri says that such is only the case when they reach their tithing times. Beis Shammai say that olives and grapes that have hardened are susceptible to ritual impurity, while Beis Hillel rule them insusceptible. Beis Shammai say that black cumin is insusceptible, while Beis Hillel rule it susceptible. They likewise differ regarding this plant’s tithes.
