A bustling city filled with the sounds of young ones is the ultimate sign of peace and prosperity. The sight of children freely gathering outdoors reflects a place where life flows simply and easily [ביאור שטיינזלץ]. This ideal reality stands in stark contrast to the destruction of the past, serving as the complete opposite of a time when the land was reduced to a desolate wasteland [אבן עזרא].
The promise of full streets signifies that the residents of the city will be fruitful and multiply, naturally filling the once empty spaces with new life [מצודת דוד]. As the boys and girls play together, their actions are an expression of pure laughter and joy [מצודת ציון]. They are able to rejoice so freely as a direct result of the great abundance and goodness that will surround them [מצודת דוד].
