Mordecai writes the letter about the Jews to the empire (Esth 8:9-8:12)

“The king’s secretaries were summoned at that time, in the third month, which is the month of Sivan, on the twenty-third day. An edict was written according to all that Mordecai commanded. It was sent to the Jews, to the satraps, the governors, and the officials of the provinces from India to Ethiopia, one hundred and twenty-seven provinces. This went to every province in its own script and to every people in its own language, and also to the Jews in their script and their language. He wrote letters in the name of King Artaxerxes. He sealed them with the king’s ring. He sent them by mounted couriers riding on swift horses that were used in the king’s service, bred from the royal herd. By these letters, the king allowed the Jews who were in every city to assemble and defend their lives. They were able to destroy, to kill, and to annihilate any armed force of any people or province that might attack them, with their children and women, and to plunder their goods, on a single day throughout all the provinces of King Artaxerxes, on the thirteenth day of the twelfth month, which is the month of Adar.”

All the king’s secretaries came to help Mordecai. This took place at Sivan, which is in the May-June time frame. The Persians had something like the later American Pony Express, with horses for their couriers. Notice that it was written in various languages and scripts for the 127 provinces of the Persian Empire. This letter had the king’s seal from his ring. This section is like that in chapter 3, when Haman was writing his letter to exterminate the Jews. This letter said that all the Jews could respond when they are attacked on the 13th day of the 12th month of Adar. They were allowed to destroy, kill, and plunder anyone attacking them. The Greek text also says that they should be allowed to follow their own laws.
