Answer: There are several amendments based on astronomy that have been introduced into the Jewish calendar. They repeat once every four years, once every seven years, and once every 50 years. We need them in order to balance the right and left lines in the middle.
In the leap year, which happens every four years, one more month is added. Once in seven years, Shemittah, the sabbatical year, comes when it is forbidden to plant crops: “Do not worry, you will not starve if you observe everything you need for six years. Do not plant anything in the seventh year.” This is an absolute ban.
Question: So, a person doesn’t question: “How so? If I haven’t planted anything, what will I eat?”
Answer: No, if one is under spiritual forces, then one functions in full accordance with astronomy, with the laws of nature, and with cosmic laws. So do not worry, you will have a harvest for this year, you do not need to plant or clean it. That is, there are special laws on how not to interfere with inanimate and vegetative nature in the seventh year.
There is also the 50th year (Yovel), when all debts are released. If someone bought or sold land to someone, then in the 50th year everything will be back to square one. In other words, the land must return to its original owner.
And who is the original owner? As stated in the Torah, when the Jews came to the land of Israel, they distributed it to everyone and wrote down every piece of land that they gave to every person to use. All this was documented, and therefore, the one who lived on this land had to return it every 50th year to the owner. And for 50 years he could rent it, cultivate it, and so on. These are very serious laws that were enacted 3,000 years ago. There are documents about how these laws were drafted, passed, and legally certified. Since many people participated in this, everything had to be formalized accordingly.
The implementation of the laws assumed that people receive from this a very serious supplement to their harvest, to their life forces. But these laws are valid only in Israel, there is no need for them abroad.
