these early nonrabbinic sources: Leviticus chapter 25 The Damascus Document of the Qumran sectarians prohibited non-cash transactions with Jews who were not members of the sect. Professor Lawrence Schiffman of New York University read this regulation as an attempt to avoid violating prohibitions on charging interest to one's fellow Jew in ; ; and . Apparently, the Qumran sect viewed prevailing methods of conducting business through credit to violate those laws. In classical rabbinic interpretation The parashah is discussed in these rabbinic sources from the era of the Mishnah and the Talmud: Leviticus chapter 25 Leviticus 25:1–34 — a Sabbatical year for the land Tractate Sheviit in the Mishnah, Tosefta, and Jerusalem Talmud interpreted the laws of the Sabbatical year in , , and and . The Mishnah asked until when a field with trees could be plowed in the sixth year. The House of Shammai said as long as such work would benefit fruit that would ripen in the sixth year. But the House of Hillel said until Shavuot. The Mishnah observed that in reality, the views of two schools approximate each other. The Mishnah taught that one could plow a grain-field in the sixth year until the moisture had dried up in the soil (that it, after Passover, when rains in the Land of Israel cease) or as long as people still plowed in order to plant cucumbers and gourds (which need a great deal of moisture). Rabbi Simeon objected that if that were the rule, then we would place the law in the hands of each person to decide. But the Mishnah concluded that the prescribed period in the case of a grain-field was until Passover, and in the case of a field with trees, until Shavuot. But Rabban Gamaliel and his court ordained that working the land was permitted until the New Year that began the seventh year. Rabbi Joḥanan said that Rabban Gamaliel and his court reached their conclusion on Biblical authority, noting the common use of the term "Sabbath" (, Shabbat) in both the description of the weekly Sabbath in and the Sabbath-year in . Thus, just as in the case of the Sabbath Day, work is forbidden on the day itself, but allowed on the day before and the day after, so likewise in the Sabbath Year, tillage is forbidden during the year itself, but allowed in the year before and the year
