Charles Ellicott Commentary Isaiah 65:22

"They shall not build, and another inhabit; they shall not plant, and another eat: for as the days of a tree shall be the days of my people, and my chosen shall long enjoy the work of their hands." — Isaiah 65:22 (ASV)

As the days of a tree ... —We may think of the cedars of Lebanon or the oaks of Bashan as providing the prophet with the ideal standard of longevity. Commonly, as by Homer and other poets, human lives have been compared to that of the leaves of deciduous trees; here they are compared to the life of the tree itself. The prophet is still speaking, not of national, but of individual life.
