Ezra 6:13-15

Then Tattenai, governor of the region beyond the River, Shethar-Boznai, and their companions diligently did according to what King Darius had sent. So the elders of the Jews built, and they prospered through the prophesying of Haggai the prophet and Zechariah the son of Iddo. And they built and finished it, according to the commandment of the God of Israel, and according to the command of Cyrus, Darius, and Artaxerxes king of Persia. Now the temple was finished on the third day of the month of Adar, which was in the sixth year of the reign of King Darius.
