A Commentary, Critical, Practical, and Explanatory on the Old and New Testaments, by Robert Jamieson, A.R. Fausset and David Brown  at sacred-texts.com
neh 0:0NEHEMIAH appears to have been the author of this book, from his usually writing in his own name, and indeed, except in those parts which are unmistakably later editions or borrowed from public documents, he usually employs the first person. The major portion of the book is occupied with a history of Nehemiah's twelve years' administration in Jerusalem, after which he returned to his duties in Shushan. At a later period he returned with new powers and commenced new and vigorous measures of reform, which are detailed in the later chapters of the book.
