III. The remainder of the passage tells us of the standing arrangements made in consequence of the alarm (vs. 16-21). First we hear what Nehemiah did with his own special 'servants,' whether these were slaves who had accompanied him from Shushan (as Stanley supposes), or his body-guard as a Persian official. He divided them into two parts--one to work, one to watch. But he did not carry out this plan with the mass of the people, probably because it would have too largely diminished the number of builders. So he armed them all. The labourers who carried stones, mortar, and the like, could do their work after a fashion with one hand, and so they had a weapon in the other. If they worked in pairs, that would be all the easier. The actual builders needed both hands, and so they had swords stuck in their girdles. No doubt such arrangements hindered progress, but they were necessary. The lesson often drawn from them is no doubt true, that God's workers must be prepared for warfare as well as building. There have been epochs in which that necessity was realised in a very sad manner; and the Church on earth will always have to be the Church militant. But it is well to remember that building is the end, and fighting is but the means. The trowel, not the sword, is the natural instrument. Controversy is second best--a necessity, no doubt, but an unwelcome one, and only permissible as a subsidiary help to doing the true work, rearing the walls of the city of God. 'He that soundeth the trumpet was by me.' The gallant leader was everywhere, animating by his presence. He meant to be in the thick of the fight, if it should come. And so he kept the trumpeter by his side, and gave orders that when he sounded all should hurry to the place; for there the enemy would be, and Nehemiah would be where they were. 'The work is great and large, and we are separated ... one far from another.' How naturally the words lend themselves to the old lesson so often drawn from them! God's servants are widely parted, by distance, by time, and, alas! by less justifiable causes. Unless they draw together they will be overwhelmed, taken in detail, and crushed. They must rally to help each other against the common foe. Thank God! the longing for manifest Christian unity is deeper to-day than ever it was. But much remains to be done before it is adequately fulfilled in the recognition of the common bond of brotherhood, which binds us all in one family, if we have one Father. English and American Christians are bound to seek the tightening of the bonds between them and to set themselves against politicians who may seek to keep apart those who both in the flesh and in the spirit are brothers. All Christians have one great Captain; and He will be in the forefront of every battle. His clear trumpet-call should gather all His servants to His side.
