ויטב הדבר לפני המן ויעש העץ
“This suggestion pleased Haman, and he made the gallows”. (Esther 5:14)
The Medrash (9:2) tells us: “Haman had 365 advisors, corresponding to Torah the days of the year, but none of them knew how to advise him as well as his wife, Zeresh. She told him, ‘If Mordechai is a Yid, you must plot wisely how to defeat and kill him because if you don’t plan wisely, you will fail. You must kill him in a way never done to his nation before. If you throw him into a furnace, Chananya and his friends were saved from a furnace. If you will throw him into a lion’s den, Doniel was thrown into a lion’s den and was saved. Perhaps you will put him in jail, but Yosef was released from jail. If you put him in a copper pot and light a fire underneath, Menashah davened to Hashem and was saved from exactly that situation. If you exile him to the desert, Mordechai's ancestors lived in the desert successfully and multiplied there. If you blind him, behold, Shimshon killed many Pelishtim after he was blinded. I suggest you hang Mordechai, because we don’t know anyone from his nation that was saved from hanging.’ It states:ויטב הדבר לפני המן ויעש העץ - ‘This suggestion pleased Haman, and he made the gallows.’”
This Medrash needs explanation. Didn't Zeresh understand that if Hashem can save someone from a lion's den, a fiery furnace, and many other situations, He can save Mordechai from being hung, too?
The Agra D’Kalah (Ekev) answers that when Yidden study and speak about a miracle that occurred in the past, that is a trigger that Hashem will perform that same miracle again. A source to this concept is in Tehillim (60:6): נתת ליראיך נס להתנוסס, which can be translated as, "You give to those who fear You miracles so they can make more miracles." They talk about Hashem's past miracles, which cause the miracles to happen again.
Zeresh said, “If you plan to throw Mordechai into a furnace, the Yidden will study the story of Chananya, Mishael, and Azaryah, who were saved from a furnace, and that will draw down the miracle for Mordechai, too. If you plan to place Mordechai in a den of lions, the Yidden will discuss the miracle that happened to Doniel, and Mordechai will be saved.” Therefore, Zeresh advised that he harm Mordechai in an unprecedented manner so that the Yidden won't have from where to draw down a miracle.
Their mistake was that they didn't realize that Mordechai was a great tzaddik in his own right, and a brand-new miracle would be created for him.
