Esther 3:2-5

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

3Then the king’s servants, who were in the king’s gate, said to Mordecai, Why dost thou transgress the king’s commandment?

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

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