Esther 9:1
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;)
On the appointed day when the king's commandment and decree were to be put into execution, the enemies of the Jews expected to gain mastery over them, but the result was turned to the contrary so that the Jews themselves gained rule over those who hated them. That reversal foreshadows a coming crisis in which rulers and others will unite against God's people. The cause of that united opposition will be the refusal of God's people to violate God's law by accepting Sunday observance. As God acted in Mordecai's time, so the Lord will vindicate His truth and His people in that future crisis.
