Mishnah 1א׳

אֵין בָּעֲרָכִין פָּחוּת מִסֶּלַע, וְלֹא יָתֵר עַל חֲמִשִּׁים סָלַע. כֵּיצַד, נָתַן סֶלַע וְהֶעֱשִׁיר, אֵינוֹ נוֹתֵן כְּלוּם. פָּחוֹת מִסֶּלַע וְהֶעֱשִׁיר, נוֹתֵן חֲמִשִּׁים סָלַע. הָיָה בְיָדָיו חָמֵשׁ סְלָעִים, רַבִּי מֵאִיר אוֹמֵר, אֵינוֹ נוֹתֵן אֶלָּא אֶחָת. וַחֲכָמִים אוֹמְרִים, נוֹתֵן אֶת כֻּלָּם. אֵין בָּעֲרָכִין פָּחוּת מִסֶּלַע, וְלֹא יָתֵר עַל חֲמִשִּׁים סֶלַע. אֵין פֶּתַח בַּטּוֹעָה פָּחוּת מִשִּׁבְעָה, וְלֹא יָתֵר עַל שִׁבְעָה עָשָׂר. אֵין בַּנְּגָעִים פָּחוּת מִשָּׁבוּעַ אֶחָד, וְלֹא יָתֵר עַל שְׁלשָׁה שָׁבוּעוֹת:

There is no evaluation less than one sela, nor more than fifty selaim. How so? If one paid a sela and became rich, one need not give any [more]. But if one gave less than a sela and became rich, one must pay fifty selaim. If one had five selaim in one's possession, Rabbi Meir says: One need not give more than one. The Sages say one must give them all. There is no evaluation less than one sela, nor more than fifty selaim. There is no re-opening for a woman who errs [in her reckoning] of the niddah count earlier than seven, nor later than after seventeen days. No signs of leprosy are shut up for less than one week, nor for more than three weeks.

Mishnah 2ב׳

אֵין פּוֹחֲתִין מֵאַרְבָּעָה חֲדָשִׁים הַמְעֻבָּרִים בְּשָׁנָה, וְלֹא נִרְאֶה יָתֵר עַל שְׁמֹנָה. שְׁתֵּי הַלֶּחֶם נֶאֱכָלוֹת אֵין פָּחוּת מִשְּׁנַיִם וְלֹא יָתֵר עַל שְׁלשָׁה. לֶחֶם הַפָּנִים נֶאֱכָל אֵין פָּחוּת מִתִּשְׁעָה וְלֹא יָתֵר עַל אַחַד עָשָׂר. קָטָן נִמּוֹל אֵין פָּחוּת מִשְּׁמֹנָה וְלֹא יָתֵר עַל שְׁנֵים עָשָׂר:

There are never less than four full months in the year, nor did it seem right [to have] more than eight. Shtei Halechem [The two leavened loaves of wheat brought as offerings on Shavuot, which permitted using the new grain for holy offerings] were eaten, never earlier than the second day, nor later than the third day. The Lechem Hapanim [twelve, specially shaped unleavened loaves offered each Shabbat on the golden table in the Temple] was eaten never earlier than the ninth day, nor later than the eleventh day. An infant may never be circumcised earlier than the eighth, nor later than the twelfth day.
