Esther 3:3

After these things did king Ahasuerus promote Haman the son of Hammedatha the Agagite, and advanced him, and set his seat above all the princes that were with him.

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

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