Talmud for Sheviit 4:2
שָׂדֶה שֶׁנִּתְקַוְּצָה, תִּזָּרַע בְּמוֹצָאֵי שְׁבִיעִית. שֶׁנִּטַּיְּבָה אוֹ שֶׁנִּדַּיְּרָה, לֹא תִזָּרַע בְּמוֹצָאֵי שְׁבִיעִית. שָׂדֶה שֶׁנִּטַּיְּבָה, בֵּית שַׁמַּאי אוֹמְרִים, אֵין אוֹכְלִין פֵּרוֹתֶיהָ בַּשְּׁבִיעִית, וּבֵית הִלֵּל אוֹמְרִים, אוֹכְלִין. בֵּית שַׁמַּאי אוֹמְרִים, אֵין אוֹכְלִין פֵּרוֹת שְׁבִיעִית בְּטוֹבָה, וּבֵית הִלֵּל אוֹמְרִים, אוֹכְלִין בְּטוֹבָה וְשֶׁלֹּא בְטוֹבָה. רַבִּי יְהוּדָה אוֹמֵר, חִלּוּף הַדְּבָרִים, זוֹ מִקֻּלֵּי בֵית שַׁמַּאי וּמֵחֻמְרֵי בֵית הִלֵּל:
A field which had been de-thorned, may be planted during the eight year. A field which had been improved [by ploughing] or fertilized may not be planted during the eighth year. A field which had been improved: the house of Shammai says its fruit may not be eaten on the seventh year, while the house of Hillel says they may be eaten. The house of Shammai says the fruit of the seventh year may not be eaten while [expressing] gratitude [to the original owner], while the house of Hillel says they may be eaten either while [expressing] gratitude [to the original owner] or not. Rabbi Yehudah says, These opinions must be switched, for this is one of the examples of a leniency of the house of Shammai and a stringency of the house of Hillel.

In the Babli, the entire first part of the Mishnah is considered R. Ṭarphon’s and everybody agrees that “a person’s courtyard acquires for him automatically”; cf. Note 106.. But if somebody collected it in his house, his house acquired for him. Rebbi Joḥanan said, even if he collected it in his house, his house did not acquire for him. For he thinks that they are his but they are not his. Does from this follow how the owner acquires his produce109The ripe produce is ownerless by biblical decree. Naturally, the owner of the property has the same right to take it as does everybody else. Anybody but the owner acquires simply by taking. How does the owner acquire, that taking from him would be theft? in a Sabbatical year? Rebbi Jeremiah wanted to say, from the moment he put them into his vessel. Rebbi Yose said, even if he put them into his vessel he did not acquire, for he thinks that they are his but they are not his110He can acquire only by a) putting the produce into his vessel and b) declaring that it is his..
