Zechariah 8:5

Verse Zechariah 8:5. The streets of the city shall be full of boys and girls] The progeny shall be numerous, healthy, and happy. Their innocent gambols and useful exercises shall be a means of health, and a proof of happiness. To be healthy, children must have exercise. But they cannot take exercise, except in the way of play and diversion: ergo, such playfulness cannot be sinful. Let them be kept from evil words, lying, swearing, and scurrility; and all the rest may be innocent.
