God saith concerning his church (Isa 62:6), I have set watchmen upon thy walls, O Jerusalem! This is Nehemiah's care here; for dead walls, without living watchmen, are but a poor defence to a city.
I. He appointed the porters, singers, and Levites, in their places to their work. This is meant of their work in general, which was to attend the temple service; it had been neglected in some degree, but now was revived. God's worship is the defence of a place, and his ministers, when they mind their duty, are watchmen on the walls. Or, in particular, he ordered them to be ready against the wall was to be dedicated, that they might perform that service in an orderly and solemn manner; and the dedication of it was its strength. That is likely to be beneficial to us which is devoted to God.
II. He appointed two governors or consuls, to whom he committed the care of the city, and gave them in charge to provide for the public peace and safety. Hanani, his brother, who came to him with the tidings of the desolations of Jerusalem, was one, a man of approved integrity and affection to his country; the other was Hananiah, who had been ruler of the palace: for he that has approved himself faithful in less shall be entrusted with more. Of this Hananiah it is said that he was a faithful man and one that feared God above many, Neh 7:2. Note, 1. Among those who fear God truly there are some who fear him greatly, and excel others in the expressions and instances of that fear; and they are worthy a double portion of that honour which is due to those that fear the Lord, Psa 15:4. There were many in Jerusalem that feared God, but this good man was more eminent for religion and serious godliness than any. 2. Those that fear God must evidence it by their being faithful to all men and universally conscientious. 3. God's Jerusalem is then likely to flourish when those rule in it, and have charge of it, who excel in virtue, and are eminent both for godliness and honesty. It is supposed, by some, that Nehemiah was now about to return to the Persian court to have his commission renewed, and that he left these two worthy men in charge with the affairs of the city in his absence. Good governors, when and where they cannot act themselves, must be very careful whom they depute.
III. He gave orders about the shutting of the gates and the guarding of the walls, Neh 7:3, Neh 7:4. See here, 1. What the present state of Jerusalem was. The city, in compass, was large and great. The walls enclosed the same ground as formerly; but much of it lay waste, for the houses were not built, few at least in comparison with what had been; so that Nehemiah walled the city in faith, and with an eye to that promise of the replenishing of it which God had lately made by the prophet, Zec 8:3, etc. Though the people were now few, he believed they would be multiplied, and therefore built the walls so as to make room for them; had he not depended upon this he might have thought walls without a city as great a reproach as a city without walls. 2. What was the care of Nehemiah for it. He ordered the rulers of the city themselves, (1.) To stand by, and see the city-gates shut up and barred every night; for in vain had they a wall if they were careless of their gates. (2.) To take care that they should not be opened in the morning till they could see that all was clear and quiet. (3.) To set sentinels upon the walls, or elsewhere, at convenient distances, who should, in case of the approach of the enemy, give timely notice to the city of the danger; and, as it came to their turn to watch, they must post themselves over against their own houses, because of them, it might be presumed, they would be in a particular manner careful. The public safety depends upon every one's particular care to guard himself and his own family against sin, that common enemy. It is every one's interest to watch, but many understand not their own interest; it is therefore incumbent upon magistrates to appoint watches. And as this people had lately found God with them in their building (else they would have built in vain), so now that the wall was built, no doubt, they were made sensible that except the Lord kept the city the watchman waked but in vain, Psa 127:1.
