“This is a copy of the letter. ‘The Great King, Artaxerxes, writes the following to the governors of the one hundred twenty-seven provinces from India to Ethiopia and to the officials under them.”
Once again, this appears only in the Greek text and not in the Hebrew text at all. The king is clearly writing to the 127 governors of the various provinces form India to Ethiopia, the great Persian Empire that had been established by King Cyrus the Great. King Cyrus had issued a decree to let the Jewish people return to Jerusalem as in 539 BCE as in Ezra, chapter 1. This would have been around the year 452 BCE, about a hundred years later about 8 years before the time of Nehemiah.
