> This would indeed be the case if not for the fact that we find a statement of the Sages;) which indicates otherwise: "The mitzvah of redemption is preferable to the mitzvah of breaking its neck; and the mitzvah of yibum is preferable to the mitzvah of chalitzah.";) The explanation of this statement is as follows: one may perform either yibum or chalitzah on a yevamah — yibum being a mitzvah, as is mentioned, and chalitzah counting as a separate mitzvah. So too, our Sages said,;) a first-born donkey may either be redeemed or have its neck broken — and each counts as a separate mitzvah.

> In the 9th Introductory Principle, the Rambam shows that land and tress may be mentioned separately in Scripture, and that they are nevertheless counted as a single mitzvah (see N214). However, he also says that when the wording of our Sages indicates, the two are counted separately.

>

> Therefore the Rambam quotes the Sifra (unlike similar statements in the Talmud), because it uses the expression "The prohibitions of planting and pruning were..." If there was only one mitzvah, they could have simply said, "The prohibition of planting was..." and omitted mention of pruning altogether. The mention of both implies that they count as separate mitzvos.

Negative Commandment 222 (Digest)

Harvesting Wild Field Crops during the Sabbatical Year

"That which grows of its own accord of your harvest, you shall not reap"—Leviticus 25:5.

It is forbidden to harvest – in normal fashion – that which grows wild in the fields during the Shemitah (Sabbatical) Year. One may only harvest it as if it were ownerless, i.e., without extensive preparation or arrangement, and not in bulk.

> The 222nd prohibition is that we are forbidden from harvesting in the normal way crops which the ground produces on its own during the seventh year [shemittah]. This means as follows: we are forbidden from working the land and cultivating trees during the shemittah year, as mentioned above. Food that was planted in the sixth year and grows in the seventh year — called safiach — may be eaten during the seventh year.;) However, it may not be harvested unless one makes a variation in the normal harvesting process.

>

>

> The source of this prohibition is G‑d's statement,;) "Do not harvest crops that grow on their own." This does not mean that one may not harvest them at all, as is evident from the verse;) "[What grows while] the land is resting may be eaten by you." The intention of the verse is that one may not harvest in the same way one harvests grain during other years. One may only gather it as if it were ownerless, without preparation or arrangement, as we shall explain.;)
