Esther 3:2-5

2And all the king’s servants, that were in the king’s gate, bowed down, and did reverence to Haman; for the king had so commanded concerning him. But Mordecai bowed not down, nor did him reverence.

3Then the king’s servants, that were in the king’s gate, said unto Mordecai, Why transgressest thou the king’s commandment?

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 down, nor did him reverence, then was Haman full of wrath.
