In the book of Esther, Haman son of Hammedatha is called what?

Answer: The Agagite

Haman son of Hammedatha, the Agagite, is called the enemy of the Jews. Sanballat, Nehemiah's foe, was the Horonite.

“After these events, King Xerxes honored Haman son of Hammedatha, the Agagite, elevating him to a position above all the princes who were with him. So the king removed the signet ring from his finger and gave it to Haman son of Hammedatha, the Agagite, the enemy of the Jews.”— Esther 3:1, 3:10 (BSB)
