There is often a crisis big with the fate of a people. Esther had the self-devotion and courage that made her a savior of her race. The wicked plots of conspirators, who seek to compass the destruction of others, often break on their own heads. Many a Haman has prepared a gibbet for a Mordecai, and finally been hung upon it himself. There is a time to fast and pray.
Nations are still wont to engage in fasting and prayer when any calamity is impending.
It is fitting, when the human arm seems too short to deliver, that a people should humble themselves before God and cry to him for succor. So, too, every individual should, in his emergency, wait humbly before God. Evil is continually destroying itself, as those demons in entering the swine. So Haman hanged himself on his own gallows.
