Land and Immortality

In Tehillim (Psalm) 49, the author states about the wise, “In their heart, their houses are forever, their dwellings are for every generation; they call by their names on plots of land."”  The Tanach (bible) frequently associates two things with immortality; descendants, “Their houses are houses forever,” and land ownership, “They call by their names on plots of land.”  It’s probably why the Tanach repeats, over and over, the centrality of the Land of Israel to the Nation of Israel.
