Hashem speaks to Moshe and instructs him to speak to Bnei Yisrael and tell them: כִּי תָבֹאוּ אֶל הָאָרֶץ, “…When you come into the land that I give you…” וְשָׁבְתָה הָאָרֶץ שַׁבָּת לַיקֹוָק, “…the land should observe a Sabbath of rest for Hashem.” (Lev. 25,2)
The Shabbat spiritually enlightens and exhilarates the Jew who observes it according to the law. In the same fashion, the land is to observe a Shabbat every seventh year. We call it Shmitah. The fields are to be given a rest and are not to be worked. When the Jewish people dwell in the land, the land has a revival. When we look at history we see how many people have conquered the Land of Israel and not one was able to make it flourish. The land lay desolate for centuries and all you could see was deserts.
When the Jewish people began to return in mass during the last century the land suddenly took on a new reality. It came back to life. It started to flourish. It seems to have been uplifted by Hashem and regained a new spiritual existence.
Israel today is not only great for itself but is contributing to the world at large. Numerous creations and inventions in virtually all fields are developed in Israel and adopted by the world. In science, medicine, technology, and every domain of modern civilization, Israel is in the forefront. The promise of Hashem to the Jewish people is coming to pass before our own eyes.
