The danger of the times is further indicated by the new rule with regard to the opening of the gates. Oriental custom would have permitted this at dawn. Nehemiah would not allow it before the full daytime, "until the sun be hot." Levites were to mount guard by day--an indication of the partially ecclesiastical character of the civil government. The city was a sort of extended temple, and its citizens constituted a Church watched over by the clergy. At night the citizens themselves were to guard the walls, as more watchers would be needed during the hours of darkness to protect the city against an assault by surprise. Now these facts point to serious danger and arduous toil. Naturally many men would shrink from the yoke of citizenship under such circumstances. It was so much pleasanter, so much easier, so much quieter for people to live in the outlying towns and villages, near to their own farms and vineyards. Therefore it was necessary to take a tenth of the rural population in order to increase that of the town. The chronicler expressly notes that "the rulers of the people" were already dwelling in Jerusalem. These men realised their responsibility. The officers were to the fore; the men who needed to be urged to their duty were the privates. No doubt there was more to attract the upper classes to the capital, while their agricultural occupations would naturally draw many of the poorer people into the country, and we must not altogether condemn the latter as less patriotic than the former. We cannot judge the relative merits of people who act differently till we know their several circumstances. Still it remains true that it is often the man with the one talent who buries his charge, because with him the sense of personal insignificance becomes a temptation to the neglect of duty. Hence arises one of the most serious dangers to a democracy. When this danger is not mastered, the management of public affairs falls into the hands of self-seeking politicians, who are ready to wreck the state for their private advantage. It is most essential, therefore, that a public conscience should be aroused and that people should realise their duty to their community--to the town in which they live, the country to which they belong.
