Esther 3:3-6

Then the king’s servants, that were in the king’s gate, said unto Mordecai, Why transgressest thou the king’s commandment? Now 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. 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.
