[If there is] a kneading trough that is on an incline, and there is dough on top and [batter containing] liquid that can moisten on the bottom: three pieces [that equal] an egg’s volume do not com-bine, but two do combine. R’ Yose says: Even two [doughs] do not combine, unless they press liquid. And if the liquid was standing, even [if each piece of dough was] like the size of mustard [seed] they combine. R’ Dosa says: Separated [pieces of] food do not combine.

[If] a stick is covered with tamei liquids, once it makes contact with a mikveh, it is tahor; [these are] the words of R’ Yehoshua. But the Sages say: Until he immerses it com-pletely. A stream [of liquid], [a flow running down] a slope, and liquid sufficient to moisten are not considered a connection for conveying tumah, nor for [producing] taharah. [Liquid in] a crevice is considered a connection for [conveying] tumah and for [producing] taharah.

From when are olives [susceptible] to contracting tumah? From when they exude the moisture of the holder, but not the mois-ture of the porous box; [this is] according to the words of Beis Shammai. R’ Shimon says: The measure [at which] moisture [ren-ders the olives susceptible] is three days. Beis Hillel say: When three [olives] stick to one another. Rabban Gamliel says: When their processing is finished; and the Sages state [their position] as he said.

If he finished harvesting [his olives], but intends to purchase [more]; [or] if he finished purchasing, but intends to borrow [more]; [or] if there befell him a mourning, or a banquet, or a compelling situation, [then] even if zavs or zavahs walk upon them, they are tahor.  If tamei beverages fell upon them, only the place in which they came into contact [with the olives] is tamei; and the moisture that seeps from them is tahor.
