The
134th mitzvah is that we are
commanded to disown everything which the land produces during the shemittah year; to release everything
which grows on our property for the use of any living creature.
The
source of this commandment is G‑d's statement, "During the seventh year, you must let it be
public and withdraw from it."
The
Mechilta [D'Rashbi] says: "Grapes and
olives were already included [in the general command]. Why were they singled
out? To make a comparison — just as
grapes, which are covered by the positive commandment, also have a prohibition,
so too everything covered by the positive commandment also has a prohibition."
I
will explain the meaning of this statement. The verse, "During the seventh
year, you must let it be public and withdraw from it" includes the release of
everything which grows during shemittah:
grapes, figs, peaches, pomegranates, wheat, barley, etc. Therefore the release
of all produce is a positive commandment. Afterwards, the verse continues,
"This also applies to your vineyard and your olive grove." But they were
already included in this commandment, which covered everything which grows from
the ground! [Our Sages therefore explain that] grapes and olives are mentioned
separately because there is a special verse which explicitly creates a prohibition on grapes: "Do not gather the
grapes on your unpruned vines." [The comparison therefore teaches us that] just
as releasing grapes is a positive commandment, and holding them is a
prohibition, so too anything which grows during shemittah — which,
as explained above, there is a positive commandment to release — there is a prohibition to hold. Therefore the
law regarding olives is identical to that regarding grapes — there is a positive commandment and a
prohibition; and other types of produce have the same law as olives.
From
the above discussion it is clear that the release of produce which grows during
shemittah counts as a positive
commandment.
The
details of this mitzvah are explained
in tractate Sh'vi'is. It is a
Biblical commandment only for produce of Eretz Yisrael.
