Esther 8:10-14

10And he wrote in the name of King Ahasuerus and sealed it with the king's signet ring. Then he sent the letters by mounted couriers riding on swift horses that were used in the king's service, bred from the royal stud,

11saying that the king allowed the Jews who were in every city to gather and defend their lives, to destroy, to kill, and to annihilate any armed force of any people or province that might attack them, children and women included, and to plunder their goods,

12on one day throughout all the provinces of King Ahasuerus, on the thirteenth day of the twelfth month, which is the month of Adar.

13A copy of what was written was to be issued as a decree in every province, being publicly displayed to all peoples, and the Jews were to be ready on that day to take vengeance on their enemies.

14So the couriers, mounted on their swift horses that were used in the king's service, rode out hurriedly, urged by the king's command. And the decree was issued in Susa the citadel.
