'Enemy of the Jews' in the Bible

Then the king took his signet ring from his hand and gave it to Haman, the son of Hammedatha the Agagite, the enemy of the Jews.

On that day King Ahasuerus gave the house of Haman, the enemy of the Jews, to Queen Esther; and Mordecai came before the king, for Esther had disclosed what he was to her.
