Ezra

The Book of Nehemiah does not specifically name its author, but both Jewish and Christian traditions recognize Ezra as the author. This is based on the fact that the Books of Ezra and Nehemiah were originally one.

The prophet who coincided with Ezra and Nehemiah is Malachi. He is considered the last prophet in the Old Testament and his prophecies are believed to have occurred during the same time period as Ezra and Nehemiah's activities in restoring Jerusalem.
