Zechariah 8:4-5

8:4 Moreover, the Lord who rules over all says, ‘Old men and women will once more live in the plazas of Jerusalem, each one leaning on a cane because of advanced age. 8:5 And the streets of the city will be full of boys and girls playing. ¹ 

[8:5]  ¹ sn The references to longevity and to children living and playing in peace are eschatological in tone. Elsewhere the millennial kingdom is characterized in a similar manner (cf. Isa 65:20; Jer 31:12-13).
