Author and Date
Nehemiah is the central figure in the book. It contains some of his own records, but he is not the author of the entire book. The same author probably wrote Nehemiah and portions of Ezra. Nehemiah arrived in Jerusalem in 445 B.C., 13 years after Ezra arrived. He returned for a further visit sometime between 433 and 423 B.C. He may have made several journeys between Persian capitals and Jerusalem in this period of 20 years
