Esther 3:4-6

4Now it came to pass, when they spake daily unto him, and he hearkened not unto them, that they told Haman, to see whether Mordecai’s matters would stand: for he had told them that he was a Jew.

5And when Haman saw that Mordecai bowed not, nor did him reverence, then was Haman full of wrath.

6And he thought scorn to lay hands on Mordecai alone; for they had shewed 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.
