Who truly sanctifies the Land of Israel - God, the Jewish people, or both? The designation of sacred spaces in Judaism has evolved dramatically over time, as evidenced by the shifting status of holy sites: while today's Jews consider the Western Wall their holiest place, the Mount of Olives held this distinction during the 10th-11th centuries. Through analysis of biblical texts, Talmudic passages, and medieval commentaries, three distinct models of sanctification emerge: divine sanctification supported by biblical and rabbinic sources, human sanctification through national connection as advocated by Rabbi Meir Simcha Hacohen, and a partnership model combining divine designation with human settlement and observance. Laws regarding Temple Mount holiness, Sabbatical year observance, and territorial boundaries for religious obligations reveal that the partnership model most accurately reflects Jewish tradition - the Land of Israel achieves its sacred status when Jews inhabit it and sanctify it through Torah study and mitzvah observance. This understanding highlights the vital importance of Jewish education in contemporary Israel, with institutions like the Schechter Institute playing a crucial role in maintaining the land's sanctity by fostering religious knowledge and practice among Israeli Jews.
