“A copy of the document was to be issued as a decree in every province, and published to all peoples. The Jews were to be ready on that day to take revenge on their enemies. So the couriers, mounted on their swift royal horses hurried out, urged by the king’s command. The decree was issued in the citadel of Susa.”
Now we are back at the Hebrew text, which summarizes the letter. A copy of this decree was sent to every one of the 127 provinces so that all the people knew about this. The Jews were to be ready on the 13th of Adar to take revenge against their enemies. This word went out by the royal couriers with their swift royal horses. The king had urged them on, since this decree came from the Persian capital of Susa.
