Here's the story:
* Haman plotted to kill all the Jews in the kingdom, but Queen Esther, herself a Jew, intervened.
* King Ahasuerus ordered Haman to be hanged on the very gallows he had built for Mordechai, a Jewish man who refused to bow down to him.
* The height of the gallows, 50 cubits, was meant to be symbolic, representing the intended height of Haman's power and his ultimate fall from grace.
It's important to note that the story of Esther is a narrative that has been interpreted in various ways over the centuries. Some view it as a historical account, while others consider it an allegory with deeper religious and moral meanings.
