Esther 3:1-2

After these events King Ahasuerus promoted Haman, the son of Hammedatha the Agagite, and advanced him and established his authority over all the princes who were with him. All the king’s servants who were at the king’s gate bowed down and paid homage to Haman; for so the king had commanded concerning him. But Mordecai neither bowed down nor paid homage.
