Shemitta is special in its requiring great faith in Hashem to fulfill, in essence relying upon a miracle. This mitzva comes with a promise that Hashem will decree a unique blessing in the sixth year to sustain us until the produce of that which is sown in the eighth year is ready for harvest.
Sefer Vayikra was given during Bnei Yisrael’s period in the desert. It is therefore telling that the Torah already relates as a given fact the situation in which they are working the fields of Eretz Yisrael, suspending work during Shemitta and Yovel, and following the rules of transactions regarding real estate in the Land among other financial matters.
We thank Hashem that we personally have found solace and refuge in our true home and hope that the entire nation in exile will move from the exile to Eretz Yisrael.
