Tevul Yom 2:8-3:1

T’vul Yom 2:8

Let’s say that a bubble formed in the wall of an earthenware jug and that the bubble was perforated with two holes, one on its inside and one on its outside. Regardless of whether they were above or below, if they’re opposite one another, the contents of the jar are rendered unclean by an av hatuma (a “father of impurity”) and by being in a tent with a corpse. If the inner hole is below and the outer hole is above, it rendered unclean by an av hatuma and by being in a tent with a corpse. If the inner hole is above and the outer hole is below, it remains clean from an av hatuma but is rendered unclean by being in a tent with a corpse.

T’vul Yom 3:1

The handles of food, which are considered connectives for an av hatuma, are also considered connectives for a t’vul yom. Let’s say that a food item was split but a small part of it remained attached. Rabbi Meir says that if one grabs the larger part and the smaller part comes up with it, it’s a connective. Rabbi Yehuda says that if one grabs the smaller part and the larger part comes up with it, then it’s a connective. Rabbi Nechemiah says we judge a connective based on picking it up by the ritually clean part (whether it’s the bigger or smaller piece); the Sages say by the ritually unclean part. In the case of other foods, those normally grabbed by the leaf should be taken by the leaf and those normally grabbed by the stalk should be taken by the stalk.
