Esther 9:1-2

On the 13th day of the 12th month, the month of Adar, the edict commanded by the king was to be carried out. On this day the enemies of the Jews had hoped to overpower them, but now the tables were turned and the Jews got the upper hand over those who hated them. The Jews assembled in their cities in all the provinces of King Xerxes to attack those seeking their destruction. No one could stand against them, because the people of all the other nationalities were afraid of them.
