The Triumph of the Jews

1 On the thirteenth day of the twelfth 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.

Now in the twelfth month, that is, the month Adar, on the thirteenth day of the same, when the king's commandment and his decree drew near to be put in execution, in the day that the enemies of the Jews hoped to have power over them, (though it was turned to the contrary, that the Jews had rule over them that hated them;)
Now in the twelfth month, which is the month of Adar, on the thirteenth day of the same, when the king's command and edict were about to be carried out, on the very day when the enemies of the Jews hoped to gain the mastery over them, the reverse occurred: the Jews gained mastery over those who hated them.
So on March 7 the two decrees of the king were put into effect. On that day, the enemies of the Jews had hoped to overpower them, but quite the opposite happened. It was the Jews who overpowered their enemies.
