Zechariah 8:4

Thus saith the LORD of hosts; There shall yet old men and old women dwell in the streets of Jerusalem, and every man with his staff in his hand for very age.

There shall yet old men and old women dwell in the streets of Jerusalem. So tranquil and prosperous shall the nation be, that wars shall no longer prematurely cut off the people: men and women shall reach advanced ages. The promise of long life was esteemed one of the greatest blessings in the Jewish theocracy, with its temporal rewards of obedience (; ). Hence, this is a leading feature in millennial blessedness (; ).

For very age - literally, for multitude of days.
