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 (a) turned to the contrary, that the Jews had rule over them that hated them;)

(a) This was by God's great providence, who turns the joy of the wicked into sorrow, and the tears of the godly into gladness.
