II. The calm heroism of Nehemiah and his wise action in the emergency are told in verses 13-15. He made a demonstration in force, which at once showed that the scheme of a surprise was blown to pieces. It is difficult to make out the exact localities in which he planted his men. 'The lower places behind the wall' probably means the points at which the new fortifications were lowest, which would be the most exposed to assault; and the 'higher places' (Auth. Ver.), or 'open places' (Rev. Ver.), describes the same places from another point of view. They afforded room for posting troops because they were without buildings. At any rate, the walls were manned, and the enemy would have to deal, not with unarmed labourers, but with prepared soldiers. The work was stopped, and trowel and spade exchanged for sword and spear. 'And I looked,' says Nehemiah. His careful eye travelled over the lines, and, seeing all in order, he cheered the little army with ringing words. He had prayed (Neh. i. 5) to 'the great and terrible God,' and now he bids his men remember Him, and thence draw strength and courage. The only real antagonist of fear is faith. If we can grasp God, we shall not dread Sanballat and his crew. Unless we do, the world is full of dangers which it is not folly to fear. Note, too, that the people are animated for the fight by reminding them of the dear ones whose lives and honour hung on the issue. Nothing is said about fighting for God and His Temple and city, but the motives adduced are not less sacred. Family love is God's best of earthly gifts, and, though it is sometimes duty to 'forget thine own people, and thy father's house,' as we have just seen, nothing short of these highest obligations can supersede the sweet one of straining every nerve for the well-being of dear ones in the hallowed circle of home. So the plan of a sudden rush came to nothing. It does not appear that the enemy was in sight; but the news of the demonstration soon reached them, and was effectual. Prompt preparation against possible dangers is often the means of turning them aside. Watchfulness is indispensable to vigour of Christian character and efficiency of work. Suspicion is hateful and weakening; but a man who tries to serve God in such a world as this had need to be like the living creatures in the Revelation, having 'eyes all over.' 'Blessed is the man that [in that sense] feareth always.' The upshot of the alarm is very beautifully told: 'We returned all of us to the wall, every one unto his work.' No time was wasted in jubilation. The work was the main thing, and the moment the interruption was ended, back to it they all went. It is a fine illustration of persistent discharge of duty, and of that most valuable quality, the ability and inclination to keep up the main purpose of a life continuous through interruptions, like a stream of sweet water running through a bog.
