“Then, according to the word sent by King Darius, Governor Tattenai of the province Beyond the River, Shethar-bozenai, and their associates did with all diligence what King Darius had ordered. The elders of the Jews built and prospered, through the prophesying of Haggai the prophet and Zechariah son of Iddo. They finished their building by command of the God of Israel and by the decree of King Cyrus, King Darius, and King Artaxerxes of Persia. This house was finished on the third day of the month of Adar, in the sixth year of the reign of King Darius.”
The leaders from Samaria were diligent in following the orders of King Darius. The elders at Jerusalem under the guidance and support of the prophets Haggai and Zechariah finished building the Temple. It is not clear where all the labor came from. Nevertheless, by the command of God, King Cyrus, King Darius, and even King Artaxerxes they completed the house of God in the 6th year of the reign of King Darius I that would be around 516 BCE. However, if it was King Darius II, it would be a century later around 418 BCE. The time of King Darius I of 516 BCE is more plausible, yet there was that dispute about the wall with King Artaxerxes.
