Why did Esther ask the King to hang the ten sons of Haman who were already dead?
We’re going to answer your question with another question. Why are Jews obligated to hear the Book of Esther read from a handwritten scroll on Purim, the Feast of Esther? Meanwhile, the Book of Maccabees relating the historical events of the holiday of Chanukah, plays no religious role on the festival of Chanukah and is not even included in the Tanach.
The reason is that the Book of Maccabees is a historical work while the Book of Esther is a religious work, composed with Divine Guidance. It relates not only to things that happened in Persia in ancient times, but has prophecy and relevance for all time. It contains prophecies and revelations still unfolding.
Haman and his sons are part of the people of Amalek. While many nations have persecuted Jews, they do not all belong to Amalek. For example, the Spanish Inquisition or Russian pogroms were horrendous – but they did not stem from Amalek. There are very specific characteristics that mark Amalek. Haman fits those categories as did the Nazis and today Islamic fanatics share many of those traits as well.
For this reason, in chapter nine after Haman’s sons were already hanged, Esther asks for them to be hanged again. A hint we will give you is that Esther is not asking King Achashveirosh to do this, she is actually asking the King of the world to do this at another time in the future when Amalek will rise again.
For a mind-exploding revelation of one of the prophecies concerning the sons of Haman that is explicitly clear in the Hebrew of the Book of Esther, please listen to Clash of Destiny: Decoding the Secrets of Israel and Yishmael and look at the enclosed study guide. You will never again think of the events in Persia as limited to history.
May the King watch over us,
