Isaiah 65:22

As the days of a tree... — We may think of the cedars of Lebanon or the oaks of Bashan as furnishing the prophet with the ideal standard of longevity. Commonly, as by Homer and other poets, the lives of men 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.
