Ester 8:3

8:3 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 

Ester 9:24

9:24 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.

[8:3]  ¹ sn As in 7:4 Esther avoids implicating the king in this plot. Instead Haman is given sole responsibility for the plan to destroy the Jews.
