The Bible

When you cross the Jordan, to come to possess the land which the L-rd, your G-d, is giving you, and you shall possess it and dwell in it, you shall keep to perform all the statutes and ordinances that I am setting before you today. These are the statutes and ordinances that you shall keep to perform in the land which the L-rd G-d of your fathers gives you to possess all the days that you live on the earth.
(Deuteronomy 11:31-32)

And He gave them lands of nations, and they inherited the toil of kingdoms. In order that they keep His statutes and observe His laws, praise G-d.
(Psalms 105:44-45)

Rambam, Known as Maimonides, foremost codifier of Jewish law (1138-1204)
The sages and the prophets did not desire the era of The messiah in order to rule over the world; nor to be exalted by the nations; nor to eat drink and celebrate. Rather, they yearned for freedom to be engaged in Torah and wisdom without any pressures or distractions, so that they would merit the World to Come.
(Laws of Kings 12:4)

Rabbi Samson Raphael Hirsch, Rabbi of Frankfurt, Germany (1808-1888)
Land and soil were never Israel’s bond of union. That function was always fulfilled solely by the common task set by the Torah. (The Nineteen Letters, #16).
The Jewish people received the gifts of a land and statehood, not … as an end unto itself, but solely as a means for carrying out the Torah, whether or not Israel would possess and retain its land, therefore, depended upon whether or not it would fulfill the demands of the Torah.
(Nineteen Letters, #8)
Israel’s nationhood does not depend on a common land. Even when the Jewish people lived on its own land, it was not the land that united them. The land and the external trappings of statehood were only a means to better fulfill the obligations of the Jews. The Torah was not given for Eretz Yisroel; Eretz Yisroel was given for the Torah!
When we pray that G-d return us to our land, we are not motivated by a desire to become a powerful nation among nations, but to be united as a nation in order to fulfill the Torah’s commandments completely.
(Horeb, p. 460)

Rabbi Elchonon Wasserman, Rosh Yeshiva of Baranovitch, Poland (1874-1941)
Eretz Yisroel is not ours in the common sense of a “homeland”. Rather, it is the territory that is designed for us to fulfill the will of G-d through it, in particular, the commandments that are dependent on the land, but it is unthinkable that Eretz Yisroel made us into a nation.
(Kovetz Maamarim vol. 1. p. 145)

Rabbi Yosef Tzvi Dushinsky, Chief Rabbi of Jerusalem (1867-1948)
However, this predestination, this divine promise, [missing what this is referring to], has its basis but in religion, for only loyalty to His laws and teachings and fundamental application of that Law in Israel’s public and private life will entitle them to the name “People of Israel” and only then can the term “Land of Israel” apply to this land
(Statement by the council of the Ashkenasic Jewish Community in Jerusalem, presented to the United Nations Special Committee on Palestine, July 1947)
