Eduyos 2:4-5

שְׁלֹשָׁה דְבָרִים אָמַר רַבִּי יִשְׁמָעֵאל לִפְנֵי חֲכָמִים בַּכֶּרֶם בְּיַבְנֶה. עַל בֵּיצָה טְרוּפָה שֶׁהִיא נְתוּנָה עַל גַּבֵּי יָרָק שֶׁל תְּרוּמָה, שֶׁהִיא חִבּוּר. וְאִם הָיְתָה כְמִין כּוֹבַע, אֵינָהּ חִבּוּר. וְעַל שִׁבֹּלֶת שֶׁבַּקָּצִיר וְרֹאשָׁהּ מַגִּיעַ לַקָּמָה, אִם נִקְצְרָה עִם הַקָּמָה, הֲרֵי הִיא שֶׁל בַּעַל הַבַּיִת, וְאִם לָאו, הֲרֵי הִיא שֶׁל עֲנִיִּים. וְעַל גִּנָּה קְטַנָּה שֶׁהִיא מֻקֶּפֶת עָרִיס, אִם יֶשׁ בָּהּ כִּמְלֹא בוֹצֵר וְסַלּוֹ מִכָּאן וּמְלֹא בוֹצֵר וְסַלּוֹ מִכָּאן, תִּזָּרֵעַ. וְאִם לָאו, לֹא תִזָּרֵעַ: Rabbi Yishmael declared three things before the Sages in the vineyard at Yavneh: Concerning an egg which was beaten together, and placed on vegetables of terumah that it acts as a connection; but if it was in the form of a helmet it does not act as a connection. And concerning an ear of corn in the harvesting, the top of which reached the standing corn that if it can be reaped together with the standing corn, it belongs to the owner; and if not, it belongs to the poor. And concerning a small garden which was surrounded by a row of vines that if it has space for the grape-gatherer and his basket on one side, and space for the grape-gatherer and his basket on the other side, it may be sown with seed; but if not, it may not be sown with seed.Mishnah Eduyot 2:4

שְׁלֹשָׁה דְבָרִים אָמְרוּ לִפְנֵי רַבִּי יִשְׁמָעֵאל, וְלֹא אָמַר בָּהֶם לֹא אִסּוּר וְהֶתֵּר, וּפֵרְשָׁן רַבִּי יְהוֹשֻׁעַ בֶּן מַתְיָא. הַמֵּפִיס מֻרְסָא בְּשַׁבָּת, אִם לַעֲשׂוֹת לָהּ פֶּה, חַיָּב, וְאִם לְהוֹצִיא מִמֶּנָּה לֵחָה, פָּטוּר. וְעַל הַצָּד נָחָשׁ בַּשַּׁבָּת, אִם מִתְעַסֵּק שֶׁלֹּא יִשְּׁכֶנּוּ, פָּטוּר, וְאִם לִרְפוּאָה, חַיָּב. וְעַל לְפָסִין אִירוֹנִיּוֹת, שֶׁהֵם טְהוֹרוֹת בְּאֹהֶל הַמֵּת וּטְמֵאוֹת בְּמַשָּׂא הַזָּב. רַבִּי אֶלְעָזָר בֶּן צָדוֹק אוֹמֵר, אַף בְּמַשָּׂא הַזָּב, טְהוֹרוֹת, מִפְּנֵי שֶׁלֹּא נִגְמְרָה מְלַאכְתָּן: They stated three things before Rabbi Yishmael, and he pronounced none of them either unlawful or lawful; and Rabbi Joshua ben Matya explained them.One who lances an abscess on the Sabbath: if it was to make an opening he is liable; if it was to bring out the pus, he is exempt. And concerning one who hunts a snake on the Sabbath: that if he was occupied with it in order that it should not bite him, he is innocent; but if that he might use it as a remedy, he is guilty. And concerning Ironian stewpots: that they do not contract impurity when under the same tent as a corpse; but become impure if they are carried by a zav. Rabbi Eliezer ben Zadok says: “Even if they are carried by a zav they remain pure, because they are unfinished.”Mishnah Eduyot 2:5
