Esther 3:4-6

4Day after day they spoke to him but he refused to comply. Therefore they told Haman about it to see whether Mordecai’s behavior would be tolerated, for he had told them he was a Jew.

5When Haman saw that Mordecai would not kneel down or pay him honor, he was enraged.

6Yet having learned who Mordecai’s people were, he scorned the idea of killing only Mordecai. Instead Haman looked for a way to destroy all Mordecai’s people, the Jews, throughout the whole kingdom of Xerxes.
