Esther 8:10-14

10Mordecai wrote in the name of King Xerxes, sealed the dispatches with the king’s signet ring, and sent them by mounted couriers, who rode fast horses especially bred for the king. 11The king’s edict granted the Jews in every city the right to assemble and protect themselves; to destroy, kill and annihilate the armed men of any nationality or province who might attack them and their women and children, and to plunder the property of their enemies. 12The day appointed for the Jews to do this in all the provinces of King Xerxes was the thirteenth day of the twelfth month, the month of Adar. 13A copy of the text of the edict was to be issued as law in every province and made known to the people of every nationality so that the Jews would be ready on that day to avenge themselves on their enemies. 14The couriers, riding the royal horses, went out, spurred on by the king’s command, and the edict was issued in the citadel of Susa.
