In rebuilding the city walls, then, Nehemiah was accomplishing two good objects; he was fortifying the place, and he was restoring its organic unity. The two advantages would be mutually helpful, because the weakness of Jerusalem was destroying the peculiar character of her life. The aristocracy, thinking it impossible to preserve the community in isolation, had encouraged and practised intermarriage with neighbouring people, no doubt from a politic regard to the advantage of foreign alliances. Although Nehemiah was not yet prepared to grapple with this great question, his fortification of Jerusalem would help the citizens to maintain their Jewish separateness, according to the principle that only the strong can be free.
The careful report which Nehemiah has preserved of the organisation of this work shows us how complete it was. The whole circuit of the walls was restored. Of course it was most necessary that nothing less should be attempted, because, like the strength of a chain, the strength of a fortress is limited to that of its weakest part. And yet--obvious as it is--probably most failures, not only in public works, but also in private lives, are directly attributable to the neglect of this elementary principle of defence. The difficulty always is to reach that kind of perfection which is suggested by the circle, rather than the pinnacle--the perfection of completeness. Now in the present instance the completion of the circuit of the walls of Jerusalem testifies to the admirable organising power of Nehemiah, his tact in putting the right men in the right places--the most important and difficult duty of a leader of men, and his perseverance in overcoming the obstacles and objections that must have been thrust in his path--all of them what people call secular qualities, yet all sustained and perfected by a noble zeal and by that transparent unselfishness which is the most powerful solvent of the selfishness of other people. There are more moral qualities involved in the art of organisation than they would suppose who regard it as a hard, mechanical contrivance in which human beings are treated like parts of a machine. The highest form of organisation is never attained in that brutal manner. Directly we approach men as persons endowed with rights, convictions, and feelings, an element of sympathy is called for which makes the organising process a much more delicate concern.
