Esther 9:1-2

Now in the twelfth month, that is, the month of Adar, on the thirteenth day, the time came for the king’s command and his decree to be executed. On the day that the enemies of the Jews had hoped to overpower them, the opposite occurred, in that the Jews themselves overpowered those who hated them. The Jews gathered together in their cities throughout all the provinces of King Ahasuerus to lay hands on those who sought their harm. And no one could withstand them, because fear of them fell upon all people.
