Darius I, The Great, Allows the Rebuilding of the Temple to Continue

Tattenai wrote to Darius inquiring about the validity of the Jewish claim to rebuild the temple. The reply from Babylon comes by a decree from Darius himself:

Ezra 6:6-8

King Darius decreed: "​Now​ you, Tattenai, governor of the province of Beyond the River, Shethar-bozenai and colleagues, the officials of the province of Beyond the River, stay away from that place.  Allow the work of this House of G-d to go on; let the governor of the Jews and the elders of the Jews rebuild this House of G-d on its site.  And I hereby issue an order concerning what you must do to help these elders of the Jews rebuild this House of G-d..."

You are looking at the Behistun Inscription that was carved on a cliff during the reign of Darius I​ who ruled from 522–486 BCE.  It features a bas-relief depiction of Darius over figures representing conquered peoples.
