Esther 3:4-6

4Day after day they warned him, but he would not comply. So they reported it to Haman to see whether Mordecai’s behavior would be tolerated, since he had told them he was a Jew.

5When Haman saw that Mordecai would not bow down or pay him homage, he was filled with rage. 6And when he learned the identity of Mordecai’s people, he scorned the notion of1 laying hands on Mordecai alone. Instead, he sought to destroy all of Mordecai’s people, the Jews, throughout the kingdom of Xerxes.
