Esther 8:12KJV

10And he wrote in the king Ahasuerus' name, and sealed with the king's ring, and sent letters by posts on horseback, riders on mules, camels, young dromedaries:

11Wherein the king granted the Jews which in every city to gather themselves together, and to stand for their life, to destroy, to slay, and to cause to perish, all the power of the people and province that would assault them, little ones and women, and the spoil of them for a prey,

12Upon one day in all the provinces of king Ahasuerus, , upon the thirteenth of the twelfth month, which the month Adar.

13The copy of the writing for a commandment to be given in every province published unto all people, and that the Jews should be ready against that day to avenge themselves on their enemies.

14the posts that rode upon mules camels went out, being hastened and pressed on by the king's commandment. And the decree was given at Shushan the palace.
