Ezra 6:13-15 NLT

13 Tattenai, governor of the province west of the Euphrates River, and Shethar-bozenai and their colleagues complied at once with the command of King Darius.
14 So the Jewish elders continued their work, and they were greatly encouraged by the preaching of the prophets Haggai and Zechariah son of Iddo. The Temple was finally finished, as had been commanded by the God of Israel and decreed by Cyrus, Darius, and Artaxerxes, the kings of Persia.
15 The Temple was completed on March 12,a during the sixth year of King Darius’s reign.
