Mishnah 1א׳

הֲרֵי עָלַי עִשָּׂרוֹן, יָבִיא אֶחָד. עֶשְׂרוֹנִים, יָבִיא שְׁנָיִם. פֵּרַשְׁתִּי וְאֵינִי יוֹדֵעַ מַה פֵּרַשְׁתִּי, יָבִיא שִׁשִּׁים עִשָּׂרוֹן. הֲרֵי עָלַי מִנְחָה, יָבִיא אֵיזוֹ שֶׁיִּרְצֶה. רַבִּי יְהוּדָה אוֹמֵר, יָבִיא מִנְחַת הַסֹּלֶת, שֶׁהִיא מְיֻחֶדֶת שֶׁבַּמְּנָחוֹת:

[One who says,] "I take upon myself an issaron [specific dry volume measure]" - he must bring one. "esronim" - he must bring two. "I specified, but I don't know what I specified" - he must bring 60 issaron. If he said, "I take upon myself a grain offering" - he may bring whichever type he wants. Rabbi Yehuda says: he should bring a fine-flour grain offering, because it is the most special of the grain offerings.

Mishnah 2ב׳

מִנְחָה, מִין הַמִּנְחָה, יָבִיא אֶחָת. מְנָחוֹת, מִין הַמְּנָחוֹת, יָבִיא שְׁתָּיִם. פֵּרַשְׁתִּי וְאֵינִי יוֹדֵעַ מַה פֵּרַשְׁתִּי, יָבִיא חֲמִשְׁתָּן. פֵּרַשְׁתִּי מִנְחָה שֶׁל עֶשְׂרוֹנִים וְאֵינִי יוֹדֵעַ מַה פֵּרַשְׁתִּי, יָבִיא מִנְחָה שֶׁל שִׁשִּׁים עִשָּׂרוֹן. רַבִּי אוֹמֵר, יָבִיא מְנָחוֹת שֶׁל עֶשְׂרוֹנִים מֵאֶחָד וְעַד שִׁשִּׁים:

"A grain offering" or "a type of grain offering" - he must bring one type. "Grain offerings" or "a type of grain offerings" - he must bring two types. "I specified, but I don't know what I specified" - he must bring all five [types]. "I specified a grain offering of esronim, but I don't know what I specified" - he must bring a grain offering of 60 issaron. Rabbi [Yehuda HaNasi] says he must bring grain offerings [of every size] from one issaron until 60 issaron.
