For Haman the son of Hammedatha, the Agagite, the enemy of all the Jews, had devised plans against the Jews to destroy them. He had cast pur (that is, the lot) in order to afflict and destroy them.

Then Esther again spoke with the king, falling at his feet. She wept and begged him for mercy, that he might nullify the evil of Haman the Agagite which he had intended against the Jews. ¹ 

But when the matter came to the king’s attention, the king ¹  gave written orders that Haman’s ²  evil intentions that he had devised against the Jews should fall on his own head. He and his sons were hanged on the gallows.
