Esther 8:11-14

In them the king granted the Jews who were in each and every city the right to assemble and to defend their lives, to destroy, to kill and to annihilate the entire army of any people or province which might attack them, including children and women, and to plunder their spoil, on one day in all the provinces of King Ahasuerus, the thirteenth day of the twelfth month (that is, the month Adar). A copy of the edict to be issued as law in each and every province was published to all the peoples, so that the Jews would be ready for this day to avenge themselves on their enemies. The couriers, hastened and impelled by the king’s command, went out, riding on the royal steeds; and the decree was given out at the citadel in Susa.
