On the Choseness of the People of Israel and the Land of Israel - Eretz Yisrael in Jewish Sources #3
The Land of Israel is beloved since the Holy One Blessed be He chose it. You find that when G-d created the world He distributed the various lands to the heavenly ministers and chose the Land of Israel for Himself. How do we know this? Moshe said, "When the Supreme One apportioned to the nations their inheritance, when He separated the children of man, He set the boundaries of the people according to the number of Children of Israel" (Devarim 32:8). He also chose the people of Israel as His portion, as it is written, "For the Lord's potion is His people; Ya'akov is the lot of His inheritance" (Devarim 32:9). Said the Holy One Blessed be He: "Let Israel, who became My portion, inherit the Land which became My potion".
The Holy One Blessed be He said to Israel, "The Land of Israel is My portion, as it is written, 'A Land which the Lord your G-d seeks out' (Devarim 11:12); and you are My portion, as it is written, 'For the Lord's portion is His people' (Devarim 32:9). It is befitting that My portion dwell in My portion.
