The Eddie B. Sit Edition and audio series of the Talmud Bavli, specifically focusing on Moed Katan, brings us to Daf Gimmel. Today’s study is dedicated to the elevation of the soul of Avraham ben Ester, and for the complete healing of Yosef ben Sarah. We begin our exploration six lines from the top of the page, starting with the words "v’lo." To set the stage, let’s review our current position in the sugya.
We learned in the Mishnah that one may water the fields during the moed and the Shemitah year. The Gemara questions this allowance, understanding why watering is permissible during the moed, despite it being a tircha. The reasoning lies in the potential loss (hefsed) that would occur without this action. The principle here is clear: although melacha is prohibited on Chol Hamoed, we do not impose a prohibition in cases of loss (bimkom pesida lo gazrinan).
When it comes to Shemitah, however, the Gemara seeks to understand the rationale behind its permissibility. A significant machloket arises between Rav Yosef and Rava regarding the classification of watering fields on Shabbat. Rava asserts that watering falls under the category of plowing (choresh), while Rav Yosef categorizes it as planting (zoreya). Both agree that during the Shemitah year, these activities are forbidden. So, how can one water fields during Shemitah? The Gemara proposes two answers.
The first answer is based on the opinion of Rebbi, who posits that the prohibition of Shemitah is only de’oraita when the Beit Hamikdash is standing. In a time when the Beit Hamikdash is not present, the prohibition is only rabbinic (derabbanan). Hence, in cases of loss, we do not apply the prohibition (bimkom pesida lo gazrinan). The Mishnah, therefore, refers to the current Shemitah, which is only rabbinic.
The second answer, attributed to Rava, suggests that even if we consider the Shemitah today to be de’oraita, the Torah only prohibits the primary categories of labor (avot melachot) and their derivatives (toldot) explicitly mentioned in the Torah. Thus, any other derivative not explicitly listed is permitted. The four prohibitions outlined in the Torah include b'tzira (picking), which is a derivative of k'tzira (harvesting), and z'mira (pruning), a derivative of z'ri'ah (planting). Therefore, watering is classified as a toledah, which is permissible.
The Gemara then challenges this interpretation, questioning whether one is truly exempt from toldot. The Gemara cites a baraita that states, "Your field shall not be sown, and your vineyard shall not be pruned," indicating that these activities are included in the prohibition. The Gemara seeks to establish the source for additional activities such as weeding (nichush) and hoeing (iddur), which are also considered toldot. Rashi clarifies the distinction between nichush, which involves uprooting weeds, and khisuach, which involves cutting at the surface level. Both activities are relevant to our discussion of the prohibitions during Shemitah.
Through the Gemara’s analysis, we learn that the prohibition extends beyond the four explicitly mentioned activities. The Gemara derives that any work done in the field or vineyard is prohibited based on the verse, "Your field shall not be sown, and your vineyard shall not be pruned." This leads to the conclusion that various forms of labor, including weeding and hoeing, are also prohibited during Shemitah.
As we delve deeper, the Gemara continues to explore additional activities that are prohibited, such as fertilizing (mezablin), removing stones (mefarkin), and covering roots (me'ashnin). Each of these activities is examined in light of the overarching principle that no work is permitted in the field or vineyard during Shemitah.
Ultimately, the question arises regarding the permissibility of watering a Shemitah field. The Gemara concludes that watering is not prohibited by Torah law but is rather a rabbinic prohibition, with the verse serving merely as an asmachta, a reminder of the prohibition rather than a definitive source. This distinction is critical, as it establishes the framework for understanding the halachic implications of our discussion.
In summary, we find ourselves navigating the intricate web of halachic distinctions regarding agricultural practices during Shemitah. The Gemara's exploration reveals the complexities of these laws, emphasizing the importance of understanding both the biblical and rabbinic dimensions of our traditions. As we engage with these texts, we are reminded of the weighty responsibilities we bear in observing the laws of Shemitah and the profound connections they forge between us and our land.
