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 

Zechariah 8:19

8:19 “The Lord who rules over all says, ‘The fast of the fourth, fifth, seventh, and tenth ²  months will become joyful and happy, pleasant feasts for the house of Judah, so love truth and peace.’

[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).

[8:19]  ² sn The fasts of the fifth and seventh months, mentioned previously (7:5), are listed here along with the observances of the fourth and tenth months. The latter commemorated the siege of Jerusalem by the Babylonians on January 15, 588 b.c. (2 Kgs 25:1), and the former the breach of the city walls on or about July 18, 586 b.c. (Jer 39:2-5).
