Esther 3:4

And when they spoke to him day after day and he would not listen to them, they told Haman , in order to see whether Mordecai’s words would stand , for he had told them that he was a Jew .

Day after day they spoke to him but he refused to comply. Therefore they told Haman about it to see whether Mordecai`s behavior would be tolerated, for he had told them he was a Jew.

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.
