Ezra 5:5-6

But their God was watching over the elders of the Jewish people. The builders were not stopped until a report could go to King Darius and his written answer could be received. This is a copy of the letter that was sent to King Darius by Tattenai, the governor of Trans-Euphrates, Shethar-Bozenai, and the other important officers of Trans-Euphrates.
