Artaxerxes is mentioned 10 times in scripture, across 2 books of the Old Testament. First named in scripture around 457 BC.
The king mentioned in Ezra 7:1, in the seventh year (B.C. 458) of whose reign Ezra led a second colony of Jews back to Jerusalem, was probably Longimanus, who reigned for forty years (B.C. 464-425); the grandson of Darius, who, fourteen years later, permitted Nehemiah to return and rebuild Jerusalem.
