Esther 3:1, 5-6

After these things King Ahasuerus promoted Haman the Agagite, the son of Hammedatha, and advanced him and set his throne above all the officials who were with him.

And when Haman saw that Mordecai did not bow down or pay homage to him, Haman was filled with fury. But he disdained to lay hands on Mordecai alone. So, as they had made known to him the people of Mordecai, Haman sought to destroy all the Jews, the people of Mordecai, throughout the whole kingdom of Ahasuerus.
