Nehemiah 6:15

In fifty and two days. — The twenty-fifth day of Elul answers to about our September 15th; and, dating back, the wall began in the latter part of July, soon after Nehemiah’s arrival. If we bear in mind that the wall was only partially overthrown, that the materials for restoration were at hand, and that the utmost skill had been shown in organising the bands of workmen, the time will not appear too short. There is no need to adopt the suggestion of Josephus, that the rebuilding occupied two years and four months.

They perceived that this work was wrought of our God. — Not miraculously, but under the Divine sanction and help. By this expression Nehemiah at once triumphs over his foes, and gives the glory where it was due. His own heroic part in the work is utterly forgotten.
