“And the L-RD spoke unto Moses in mount Sinai, saying: Speak unto the children of Israel, and say unto them: When ye come into the land which I give you, then shall the land keep a Sabbath unto the L-RD.”
– Leviticus 25:1-2, JPS 1917 Tanach
At the beginning of the parashas, an emphasis is placed on the Shemitah commandment, in particular, being given at Mt Sinai. All of the commandments were given at Sinai; therefore, the question may be asked, why is Shemitah singled out from amongst the other commandments? First of all, it may be understood within the context of emunah (faith). For, H’Shem guarantees, “I will command My blessing upon you in the sixth year, and it shall bring forth produce for the three years” (Leviticus 25:21, JPS 1917 Tanach).
To rely on H’Shem’s word that he would bestow a blessing upon the children of Israel, so that their crops would produce an abundance of yield, enough to last for three years, this is an act of emunah (faith). Only H’Shem could make this guarantee; so, inasmuch that Torah specifically notes the commandment to observe the Shemitah year, wherein the seventh year the land is to lie fallow, this is a reminder that H’Shem gave the commandment on Mt. Sinai, He is the Guarantor. Man could not guarantee such a promise; only G-d could assure the people that by placing their trust in him through following the commandment of Shemitah, He would provide for them until the new crop of the following year produced a yield.
The Shemitah cycle also conveys the essential truth, the epitome of historical realization from a Biblical perspective, that after six thousand years, there will be a Sabbatical Millenium (Nachmanides, otherwise known as the Ramban). The thousand year Sabbath begins with the reign of Moshiach (Messiah) in Yerushalayim (Jerusalem); this is considered the first part of Olam Haba (the World to Come). Therefore, in light of this expectation, we are to prepare ourselves in this world, so that we may partake of the reward, likened to a banquet, in the next world.
“‘This world is like a corridor before the world to come [Olam Haba]; prepare thyself in the corridor, so that thou mayest enter into the banquet hall.'” – Pirkei Avos 4: 21
