Mishnah 1א׳

שַׁמַּאי אוֹמֵר, כָּל הַנָּשִׁים דַּיָּן שְׁעָתָן. וְהִלֵּל אוֹמֵר, מִפְּקִידָה לִפְקִידָה, אֲפִלּוּ לְיָמִים הַרְבֵּה. וַחֲכָמִים אוֹמְרִים, לֹא כְדִבְרֵי זֶה וְלֹא כְדִבְרֵי זֶה, אֶלָּא מֵעֵת לְעֵת מְמַעֶטֶת עַל יַד מִפְּקִידָה לִפְקִידָה, וּמִפְּקִידָה לִפְקִידָה מְמַעֶטֶת עַל יַד מֵעֵת לְעֵת. כָּל אִשָּׁה שֶׁיֶּשׁ לָהּ וֶסֶת, דַּיָּהּ שְׁעָתָהּ. הַמְשַׁמֶּשֶׁת בְּעִדִּים, הֲרֵי זוֹ כִפְקִידָה, מְמַעֶטֶת עַל יַד מֵעֵת לְעֵת וְעַל יַד מִפְּקִידָה לִפְקִידָה:

Shammai says: All women are judged [impure] from the time [they discover that their period has begun]; Hillel says: From the time of [one] examination [to the next] examination, even if [that spans] many days. But the Sages say: Not like the words of [Shammai] and not like the words of [Hillel]; rather, [she is judged impure] from the [day preceding the discovery] if this is less than [the span] between the last examination and the current examination; [she is judged impure] from [the span] between the last examination and the current examination if this is less than [a day preceding the discovery]. [For] all women who have regular periods, the usual onset time of her period is sufficient [to be judged impure]. Using cloth [to clean herself after sexual relations] is considered an examination, and [this act] lessens [either] the preceding day's span or [the span] between the last examination and the current examination.

Mishnah 2ב׳

שַׁמַּאי אוֹמֵר, מִקַּב לְחַלָּה. וְהִלֵּל אוֹמֵר, מִקַּבָּיִם. וַחֲכָמִים אוֹמְרִים, לֹא כְדִבְרֵי זֶה וְלֹא כְדִבְרֵי זֶה, אֶלָּא קַב וּמֶחֱצָה חַיָּבִים בְּחַלָּה. וּמִשֶּׁהִגְדִּילוּ הַמִּדּוֹת אָמְרוּ, חֲמֵשֶׁת רְבָעִים חַיָּבִין. רַבִּי יוֹסֵי אוֹמֵר, חֲמִשָּׁה, פְּטוּרִין. חֲמִשָּׁה וָעוֹד, חַיָּבִין:

Shammai says: [Dough] greater than a kav [a measure] [is obligated] in [the law of] challah [setting aside a portion of dough for the priests]. Hillel says: From two kabbim. The Sages say: Not like the words of [Shammai] and not like the words of [Hillel]; rather, one and a half kav is obligated in challah. After they made the measures larger they said: Five quarters are obligated. Rabbi Yossi says: Five are not obligated; five and more are obligated.
