Esther 3:2-5

2All the king’s advisers were at the king’s gate, kneeling and bowing to Haman with their faces touching the ground, because the king had commanded it. But Mordecai would not kneel and bow to him.

3Then the king’s advisers at the king’s gate asked Mordecai, “Why do you ignore the king’s command?”

4Although they asked him day after day, he paid no attention to them. So they informed Haman to see if Mordecai’s actions would be tolerated, since Mordecai had told them that he was a Jew.

5When Haman saw that Mordecai did not kneel and bow to him, Haman was infuriated.
