The highly dangerous nature of his undertaking and the necessity for exercising the utmost caution were apparent to Nehemiah as soon as he approached Jerusalem. Watchful enemies at once showed themselves annoyed "that there was come a man to seek the welfare of the children of Israel."[161] It was not any direct injury to themselves, it was the prospect of some favour to the hated Jews that grieved these people; though doubtless their jealousy was in part provoked by dread lest Jerusalem should regain the position of pre-eminence in Palestine which had been enjoyed during her depression by the rival city of Samaria. Under these circumstances Nehemiah followed the tactics which he had doubtless learnt during his life among the treacherous intrigues of an Oriental court. He did not at first reveal his plans. He spent three days quietly in Jerusalem. Then he took his famous ride round the ruins of the city walls. This was as secret as King Alfred's exploration of the camp of the Danes. Without breathing a word of his intention to the Jews, and taking only a horse or an ass to ride on himself and a small body of trusty attendants on foot, Nehemiah set out on his tour in the dead of night. No doubt the primary purpose of this secrecy was that no suspicion of his design should reach the enemies of the Jews. Had these men suspected it they would have been beforehand with their plans for frustrating it; spies and traitors would have been in the field before Nehemiah was prepared to receive them; emissaries of the enemy would have perverted the minds even of loyal citizens. It would be difficult enough under any circumstances to rouse the dispirited people to undertake a work of great toil and danger. If they were divided in counsel from the first it would be hopeless. Moreover, in order to persuade the Jews to fortify their city, Nehemiah must be prepared with a clear and definite proposal. He must be able to show them that he understands exactly in what condition their ruined fortifications are lying. For his personal satisfaction, too, he must see the ruins with his own eyes. Ever since the travellers from Jerusalem who met him at Susa had shocked him with their evil tidings, a vision of the broken walls and charred gates had been before his imagination. Now he would really see the very ruins themselves, and ascertain whether all was as bad as it had been represented. [161] Neh. ii. 10.
