Esther 3:1, 5-6

After these things did king Ahasuerus promote Haman the son of Hammedatha the Agagite, and advanced him, and set his seat above all the princes that were with him.

And when Haman saw that Mordecai bowed not down, nor did him reverence, then was Haman full of wrath. But he thought scorn to lay hands on Mordecai alone; for they had made known to him the people of Mordecai: wherefore Haman sought to destroy all the Jews that were throughout the whole kingdom of Ahasuerus, even the people of Mordecai.
