Esther 8:11-14

wherein the king granted the Jews that were 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, their little ones and women, and to take the spoil of them for a prey, upon one day in all the provinces of king Ahasuerus, namely, upon the thirteenth day of the twelfth month, which is the month Adar. A copy of the writing, that the decree should be given out in every province, was published unto all the peoples, and that the Jews should be ready against that day to avenge themselves on their enemies. So the posts that rode upon swift steeds that were used in the king’s service went out, being hastened and pressed on by the king’s commandment; and the decree was given out in Shushan the palace.
