זכריה, פרק ח׳, פסוק ד׳

A profound message of comfort and absolute security shapes the future vision of Jerusalem. To ease the fears of the people regarding the possibility of another exile [מלבי״ם], God issues a firm declaration ensuring that this promised era will undoubtedly come to pass [רד״ק]. The resulting time will be defined by deep peace, rest, and prosperity, where the city will be filled with residents experiencing remarkable longevity [אבן עזרא, ביאור שטיינזלץ].

The sight of elderly men and women gathering openly in the city squares represents a dramatic shift in living conditions. During difficult times, human life is often cut short. However, in this future era of safety, the elderly will freely step outside to rest, warm themselves in the sun, and converse, completely untouched by the fear of danger or sickness [ביאור שטיינזלץ]. The peace will be so absolute that even the most physically vulnerable members of society will occupy public spaces without any anxiety [מלבי״ם]. The natural weaknesses that accompany old age will no longer confine them to their homes; instead, they will socialize out in the streets much like younger people do [מצודת דוד].

The reliance on a walking stick is meant to be understood literally [רד״ק, מצודת ציון]. This detail highlights the extreme old age the residents will achieve, living for so many days that they will naturally require physical support to walk [רש״י, ביאור שטיינזלץ]. Yet, this creates a unique balance. Even though their many years of life will make a cane necessary, they will still retain the vitality and strength to leave their houses and actively participate in the life of the city [מצודת דוד].
