Artaxerxes
Easton's Dictionary
The Greek form of the name of several Persian kings. (1.) The king who obstructed the rebuilding of the temple (Ezra 4:7). He was probably the Smerdis of profane history.
(2.) 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.
Smith's Dictionary
(the great warrior).
The first Artaxerxes is mentioned in (Ezra 4:7) and appears identical with Smerdis, the Magian impostor and pretended brother of Cambyses, who usurped the throne B.C. 522, and reigned eight months. In (Nehemiah 2:1) we have another Artaxerxes. We may safely identify him with Artaxerxes Macrocheir or Longimanus, the son of Xerxces, who reigned B.C. 464-425.
