Esther 8:10-14

10Mordecai wrote in the name of King Xerxes and sealed it with the royal signet ring. He sent the documents by mounted couriers riding on swift horses bred from the royal mares.

11By these letters the king permitted the Jews in each and every city the right to assemble and defend themselves, to destroy, kill, and annihilate all the forces of any people or province hostile to them, including women and children, and to plunder their possessions. 12The single day appointed throughout all the provinces of King Xerxes was the thirteenth day of the twelfth month, the month of Adar.1

13A copy of the text of the edict was to be issued in every province and published to all the people, so that the Jews would be ready on that day to avenge themselves on their enemies. 14The couriers rode out in haste on their royal horses, pressed on by the command of the king. And the edict was also issued in the citadel of Susa.
