Ezra 6:14-15

14So 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.

15Now 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.
