After these things happened, King Xerxes honored Haman son of Hammedatha the Agagite. He gave him a new rank that was higher than all the important men.
All the royal officers at the king's gate would bow down and kneel before Haman, as the king had ordered. But Mordecai would not bow down or show him honor.
Then the royal officers at the king's gate asked Mordecai, "Why don't you obey the king's command?"
And they said this to him every day. When he did not listen to them, they told Haman about it. They wanted to see if Haman would accept Mordecai's behavior because Mordecai had told them he was Jewish.
When Haman saw that Mordecai would not bow down to him or honor him, he became very angry.
He thought of himself as too important to try to kill only Mordecai. He had been told who the people of Mordecai were, so he looked for a way to destroy all of Mordecai's people, the Jews, in all of Xerxes' kingdom.
