Shammai says: All women it suffices for them their time. But Hillel says: From examination to examination, even for many days. And the Sages say neither in accordance with the words of this one and neither in accordance with the words of that one; ra-ther, “twenty-four hours” reduces “from examination to examination,” and “from examination to examination” reduces “twenty-four hours.” Any woman who has a fixed period, it suffices for her her time. When [a woman] has marital relations with examination cloths, this is the equivalent of an examination; it reduces “twenty-four hours” and “from examination to examination.”

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.

This is the rule: Whoever swears to make it more lenient for himself —- is liable; to make it more stringent for himself —- is exempt.
