III. That there shall be in Jerusalem a great increase of people, and all the marks and tokens of a profound tranquillity, When it has become a city of truth and a mountain of holiness, it is then peaceable and prosperous, and every thing in it looks bright and pleasant. 1. You may look with pleasure upon the generation that is going off the stage, and see them fairly quitting it in the ordinary course of nature, and not driven off from it by war, famine, or pestilence (v. 4): In the streets of Jerusalem, that had been filled with the bodies of the slain, or deserted and left desolate, shall now dwell old men and old women, who have not been cut off by untimely deaths (either through their own intemperance or God's vengeance), but have the even thread of their days spun out to a full length; they shall feel no distemper but the decay of nature, and go to their grave in a full age, as a shock of corn in his season. They shall have every one his staff in his hand, for very age, to support him, as Jacob, who worshipped, leaning upon the top of his staff, Heb. xi. 21. Old age needs a support, and should not be ashamed to use it, but should furnish itself with divine graces, which will be the strength of the heart and a better support than a staff in the hand. Note, The hoary head, as it is a crown of glory to those that wear it, so it is to the places where they live. It is a graceful thing to a city to see abundance of old people in it; it is a sign, not only of the healthfulness of the air, but of the prevalence of virtue and the suppression and banishment of those many vices which cut off the number of men's months in the midst; it is a sign, not only that the climate is temperate, but that the people are so. 2. You may look with as much pleasure upon the generation that is rising up in their room (v. 5): The streets of the city shall be full of boys and girls playing in the streets. This intimates, (1.) That they shall be blessed with a multitude of children; their families shall increase and multiply, and replenish the city, which was an early product of the divine blessing, Gen. i. 28. Happy the man, happy the nation, whose quiver is full of these arrows! They shall have of both sexes, boys and girls, in whom their families shall afterwards be joined, and another generation raised up. (2.) That their children shall be healthful, and strong, and active; their boys and girls shall not lie sick in bed, or sit pining in the corner, but (which is a pleasant sight to parents) shall be hearty and cheerful, and play in the streets. It is their pleasant playing age; let us not grudge it to them; much good may it do them and no harm. Evil days will come time enough, and years of which they will say that they have no pleasure in them, in consideration of which they are concerned not to spend all their time in play, but to remember their Creator. (3.) That they shall have great plenty, meat enough for all their mouths. In time of famine we find the children swooning as the wounded, in the streets of the city, Lam. ii. 11, 12. If they are playing in the streets, it is a good sign that they want for nothing. (4.) That they shall not be terrified with the alarms of war, but enjoy a perfect security. There shall be no breaking in of invaders, no going out of deserters, no complaining in the streets (Ps. cxliv. 14); for, when there is playing in the streets, it is a sign that there is little care or fear there. Time was when the enemy hunted their steps so closely that they could not go in their streets (Lam. iv. 18), but now they shall play in the streets and fear no evil. (5.) That they shall have love and peace among themselves. The boys and girls shall not be fighting in the streets, as sometimes in cities that are divided into factions and parties the children soon imbibe and express the mutual resentments of the parents; but they shall be innocently and lovingly playing in the streets, not devouring, but diverting, one another. (6.) That the sports and diversions used shall be all harmless and inoffensive; the boys and girls shall have no other play than what they are willing that persons should see in the streets, no play that seeks corners, no playing the fool, or playing the wanton, for it is the mountain of the Lord, the holy mountain, but honest and modest recreations, which they have no reason to be ashamed of. (7.) That childish youthful sports shall be confined to the age of childhood and youth. It is pleasing to see the boys and girls playing in the streets, but it is ill-favoured to see men and women playing there, who should fill up their time with work and business. It is well enough for children to be sitting in the market-place, crossing questions (Matt. xi. 16, 17), but it is no way fit that men, who are able to work in the vineyard, should stand all the day idle there, Matt. xx. 3.
