Esther 9:17

Now in the twelfth month (that is, the month Adar), on the thirteenth day when the king’s word and law had reached the point for them to be done, on the day when the enemies of the Jews hoped to gain power over them, it was turned around so that the Jews themselves gained power over those who hated them.

The Jews assembled in their cities throughout all the provinces of King Ahasuerus to send forth their hand against those who sought their calamity; and no one could stand before them, for the dread of them had fallen on all the peoples.
