We may not use the produce of the Sabbatical year for commercial activity.1Avodah Zarah 62a derives this insight from the exegesis of Leviticus 25:6. The fact that the Rambam does not mention that prooftext here has raised a question among the commentaries: Does he consider the prohibition against using the produce of the Sabbatical year as merchandise as Scriptural or Rabbinic in origin? If one desires to sell a small amount2Enough for three meals (Kessef Mishneh). of the produce of the Sabbatical year, he may.3For selling a small amount is not considered as using the produce as merchandise. The money he receives [in return] has the same status as the produce of the Sabbatical year. He should use it to purchase food4For humans (see Chapter 5, Halachah 12). and eat that food according to the restrictions of the holiness of the Sabbatical year.5Sukkah 40b derives this from the exegesis of Leviticus 25:12: "It shall be holy for you." Just as the sanctity of articles that are "holy," consecrated to the Temple, is transferred to the money received for them, so too, the holiness of the produce of the Sabbatical year is transferred to the money received for it. The produce that was sold retains the holiness it possessed previously.6See Halachot 6-7.הלכה ב

[In the Sabbatical year,] one should not reap vegetables from a field7These refer to vegetables that grow under the circumstances described in Chapter 4, Halachah 4, or the like. Otherwise, the vegetables would be forbidden as sifichin. See the gloss of the Kessef Mishneh to Halachah 12. and sell them, nor should one charge a fee for dyeing with shells [from produce] of the Sabbatical year, because this is using the produce of the Sabbatical year for commercial activity.8This is forbidden even if one intends to use the proceeds to purchase food which he will eat according to the requirements of the holiness of the Sabbatical year [the Rambam's Commentary to the Mishnah (Shivi'it 7:3)]. If one reaped vegetables to partake of them and some were left over, he may sell the remainder.9For it is obvious that he gathered the vegetables for his own personal use. The proceeds are considered as the produce of the Sabbatical year. Similarly, if a person reaped vegetables for himself and his son or grandson took some of them and sold them, [the sale] is permitted10Since the person who reaped the produce was not the one who sold it, there is no prohibition involved (Radbaz). and the proceeds are considered as the produce of the Sabbatical year.הלכה ג

When the produce of the Sabbatical year is sold, it should not be sold by measure, nor by weight, nor by number, so that it will not appear that one is selling produce in the Sabbatical year. Instead, one should sell a small amount by estimation to make it known that [the produce] is ownerless.11The Radbaz states that one should also sell the produce at a lower price than usual. And the proceeds of the sale should be used to purchase other food.הלכה ד

One may package those entities that are usually packaged to bring home to sell in the market by estimation in the manner that one packages produce to bring home,12When a person packages produce to take home from his field, he is not precise with regard to the amount he takes. not like one packages it for the market13When a person packages produce to sell in the marketplace, he is careful to package an exact amount, so that the sale will be honest.The Ra'avad differs with the Rambam's ruling, maintaining that as long as the type of produce is packaged to bring home, it can be packaged for sale. The Radbaz and the Kessef Mishneh support the Rambam's interpretation, explaining that when produce is packaged for sale, it is possible for an onlooker to appreciate that this is the intent from the way that it is packaged. so that one will not sell in a constrained manner. Produce that is packaged only for the marketplace should not be packaged.

Produce from the Diaspora which were brought into Eretz Yisrael should not be sold by measure, nor by weight, nor by number. Instead, they should be sold by estimation like the produce of Eretz Yisrael.14For an onlooker will not understand that the produce is from the Diaspora and will think that the produce of the Sabbatical year is being sold in an ordinary manner. If it was obvious that it was produce from the Diaspora, it is permitted [to sell it in the ordinary manner].הלכה ו

There is a stringency that applies to the produce of the Sabbatical year and not to articles consecrated [to the Temple]. When one redeems consecrated articles, the consecrated article loses its sacred status and that status is conveyed to the money.15See Hilchot Arachin 6:4. This is not so with regard to the produce of the Sabbatical year. When one sells the produce of the Sabbatical year, the status of the produce is conveyed to the money.16And it must be used to purchase food which will be eaten with the stringencies befitting the holiness of the produce of the Sabbatical year. The produce itself, however, does not lose its status and it is not considered as produce of the other years. [This is derived from] the use of the word tihiyeh17Leviticus 25:12. See the Sifra to this verse. [in the command regarding the produce of the Sabbatical year. That term implies that the produce] will be in its state at all times. And since the produce of the Sabbatical year is described18Leviticus 25:12. See the Sifra to this verse. as "holy," its status is conveyed to the money paid for it.19As is true with regard to the money used to redeem consecrated objects. Thus the final [object purchased]20I.e., the food to be eaten; see the following halachah, for an explanation. receives the status of the Sabbatical year and [the status of] the produce itself remains as before.הלכה ז

What is implied? A person purchased meat with the produce of the Sabbatical year or the proceeds from its sale. The meat is given the status of that produce and must be eaten [as befits the holiness of] the produce of the Sabbatical year. And one must rid oneself of it when one one must rid oneself of that produce.21See Chapter 7, Halachah 1, which speaks about this subject. If one used that meat or the proceeds from its sale to purchase fish, the meat is considered as ordinary food and [the holiness of the Sabbatical year] is conveyed upon the fish. If one used that fish or the proceeds from its sale to purchase oil, the fish is considered as ordinary food and [the holiness of the Sabbatical year] is conveyed upon the oil. If one used that oil or the proceeds from its sale to purchase honey, the oil is considered as ordinary food and [the holiness of the Sabbatical year] is conveyed to the honey. One must rid oneself of the original fruit and the honey as one must rid oneself of the produce of the Sabbatical year. Neither of them may be used to make a compress, nor may they be ruined, as is the rule with regard to the produce of the Sabbatical year.הלכה ח

The holiness of the produce of the Sababtical year may be transferred only through a sale. When does this apply? With regard to the original produce.

When one is transferring the holiness of produce that was exchanged [for produce of the Sabbatical year], one may not transfer it to a domesticated animal, fowl, or beast, that is alive,23Note the parallel to Hilchot Ma'aser Sheni 4:6. There it is stated that if one makes such a transfer, it is not effective. The commentaries state that the same law applies in the present instance. lest they be left alive and one raise herds [of animals imbued with the holiness of the Sabbatical year]. Needless to say, this24That the holiness may not be transferred to a living animal. applies with the produce of the Sabbatical year itself. One may, however, transfer the holiness of this produce to animals that have been slaughtered.25For the abovementioned difficulty does not apply.הלכה י

Money received for produce of the Sabbatical year may not be used to pay a debt.26This is considered similar to using it to purchase merchandise. Nor may one use it to repay shushbinut27Shushbinut refers to a custom where a person sends money to a friend as a present at the time of the friend's wedding. Afterwards, when the person himself marries, his friend is expected to send a similar sum to him as a present. The money is considered as a debt and if he fails to so, he can be sued in court. See Hilchot Zechiyah UMatanah, ch. 7. or return a favor.28I.e., the person once lent him money. He may not use money received in return for the produce of the Sabbatical year to offer that person a loan (Radbaz, Hilchot Matanot Aniyim 6:17). One should not use it to pay a pledge of charity for the poor in the synagogue.29Since the person pledged money, satisfying his obligation with the produce of the Sabbatical year is comparable to using it to pay a debt. One may, however, send it for purposes associated with the acts of kindness,30I.e., providing that person with the meal of comfort at the time of bereavement (ibid.). but one must notify the recipients.31So that they treat it with the appropriate holiness and rid themselves of it when required. Also, the recipient will realize that he need not be overly grateful, for he was not given produce of full value.Similarly, it may not be used to purchase servants, landed property, or a non-kosher animal.32For as mentioned above, such money may only be used for the purchase of food. If it was used for those purposes, one should purchase ordinary food with a commensurate sum and partake of it [as befits the holiness of the Sabbatical year],33Our translation is taken from the Rambam's Commentary to the Mishnah (Shivi'it 8:8). as was explained with regard to the second tithes.34See Hilchot Ma'aser Sheni 7:17. One may not purchase pairs of doves for [the sacrifices of] zavim, zavot, or women after childbirth,35As explained in Hilchot Mechusrei Kapparah, ch. 1, these individuals are required to bring pairs of doves as part of their sacrifices to emerge from impurity. or sin-offerings or guilt offerings.36In his Commentary to the Mishnah (Ma'aser Sheni 1:7), the Rambam explains that money from the second tithes - and thus by extension, money from the Sabbatical year - may not be used for these sacrifices, for they are not eaten by their owners. If he purchased [these offerings with these funds], he should purchase food with a commensurate sum and partake of it [as befits the holiness of the Sabbatical year]. One should not apply oil from the Sabbatical year to utensils or hides.37For then, he is not receiving direct physical benefit from the oil. See Chapter 5, Halachah 7. If one did so, one should purchase food with a commensurate sum and partake of it38But not use it for smearing. See Chapter 5, Halachah 12, and notes. [as befits the holiness of the Sabbatical year].

He may, however, give them to a person who draws water from a well to provide him with drinking water.41For that is like using the money to purchase drinking water [the Rambam's Commentary to the Mishnah (Shivi'it 8:5)]. He may not, however, give it to him to draw water for other purposes (Radbaz). It is permitted to give the produce of the Sabbatical year or money received in return for it to a craftsman as a present.42Even though the craftsman will be receiving a present and will return the favor to the person in some way, that is permitted.

When a person tells a worker: "Here is an isar.43A coin of small value used in the Talmudic period.

It is not considered as money received in return for produce of the Sabbatical year. Instead, he may use it for whatever he desires.45I.e., it is not restricted to being used for eating or drinking as is money received in return for produce of the Sabbatical year. The worker was not penalized46See the rationale given in the following halachah. in that his wage would be considered as money received for the produce of the Sabbatical year. If he told him: "Gather a vegetable for me today for it," [his wage] is considered as money received in return for produce of the Sabbatical year.47The wording used by the employer clearly establishes such a connection. As the Radbaz explains, in the first instance, it appears that he is hiring him to work that day. In the second instance, it appears that he is hiring him to reap vegetables. He may use it only for eating and drinking like the produce of the Sabbatical year.הלכה יג

When donkey-drivers perform work with the produce of the Sabbatical year that is forbidden - e.g., they bring more than the [minimal amount] of produce48While it is permitted to bring a small amount of produce in the Sabbatical year from the fields as stated in Chapter 4, Halachah 24, these donkey-drivers brought oversized loads as they would do in other years. - their wages are considered as money received in return for produce of the Sabbatical year.49And may only be used for food and drink. This stringency applies even if their employer hired them using wording that would be permitted when hiring a worker. This is a penalty imposed upon them.Why was a penalty imposed on the wages of a donkey-driver and not on the wages of a hired worker? Because the latter receives a minimal wage. Hence, he was not penalized so that [he could earn] his livelihood.

When a person purchases a loaf of bread from a baker for a pundiyon,50A coin of the Talmudic period that was twice the worth of an isar. and tells him: "When I harvest vegetables [grown in the Sabbatical year] from the field, I will bring them to you for it."51I.e., rather than pay him now, he promises that he will pay him in the future by bringing him vegetables. this is permitted.52The purchaser is not considered to be paying a debt with the produce from the Sabbatical year. Instead, since at the time he took the loaf of bread, he already stipulated that the exchange would be made, this is considered as an exchange for the produce of the Sabbatical year, which is permitted [the Rambam's Commentary to the Mishnah (Shivi'it 8:4)].The commentaries explain that this concept is alluded to by the Rambam's addition of the word bo, meaning "for it." This implies that the purchaser is clearly stipulating that he is making an exchange. The loaf of bread is considered as the produce of the Sabbatical year.53For it was received in exchange for produce of the Sabbatical year. If he purchases the loaf without making any qualifications,54And does not pay him immediately. he should not pay him with money received for the produce of the Sabbatical year, because one should not use that money to pay debts.55As stated in Halachah 10.

One may partake of the produce of the Sabbatical year [in expectation56Or even in return for having perfomed a favor. that the recipient will return] the favor and when there are no such expectations.57The Rambam is adding this point, to emphasize that we do not follow the opinion of Rabbi Yehudah who maintains that the School of Hillel permitted a person to partake of the produce of the Sabbatical year that belongs to a colleague only in expectation of favors (see Ediyot 5:1). Rabbi Yehudah's rationale is that it is not desirable for any person to have free access to a colleague's field and enter it at all times. What is implied [by the idea of eating in expectation of the return of the favor]? One may give a colleague the produce of the Sabbatical year as if he had already performed a favor for him58In his Commentary to the Mishnah (Shivi'it 4:1), the Rambam explains that the person tells a colleague: "Reap in my field and then I will reap in your field." or invite him into his garden to eat as one who performed a favor for him.When a person was given the produce of the Sabbatical year as a present or he inherited it, he should partake of it in the same manner as if he gathered this produce from the field himself.59There is a difference of opinion regarding this issue in Shivi'it 9:9 and the Rambam's ruling does not follow either of the views mentioned there. Nevertheless, it can be explained that the mishnah is speaking according to Rabbi Eliezer's perspective and Rabbi Eliezer follows the opinion of the School of Shammai. The Rambam's ruling reflects the position that would be given by the School of Hillel, whose opinion is accepted as halachah.
