Many "mitzvot" in the Torah are about the Land of Israel. The Talmud and later books call these "mitzvot" “commandments connected to the Land” because Jews can only do them in the Land of Israel. For example, Jews give gifts to the poor or the priests from their fields every year, take fruit or animals to the Temple in Jerusalem, and must stop working on the land every seven years (the “shmittah” – sabbatical year).
