Shammai says: Challah is due from one kav. But Hillel says: From two kavs. And the Sages say neither in accordance with the words of this one nor in accordance with the words of this one; rather, a kav and a half is liable to challah. And when the units were increased they said: Five revaim are subject [to challah]. R' Yose says: Five revaim are exempt, five plus are liable.

Hillel says: A Full hin of drawn water disqualifies a mikveh that is incomplete. [Hillel chose the above wording] only because a person is required to speak in the language of his teacher. But Shammai says: Nine kavs. And the Sages say neither in accord-ance with the words of this one nor in accordance with the words of that one; rather, [the matter was in dispute] until two weavers came from the Dung Gate of Jerusalem, and they testified in the name of Shemayah and Avtalyon that three lugin of drawn water disqualify a mikveh. And the Sages upheld their words.
