Esther 4:4-5

4When Esther's young women and her eunuchs came and told her, the queen was deeply distressed. She sent garments to clothe Mordecai, so that he might take off his sackcloth, but he would not accept them.

5Then Esther called for Hathach, one of the king's eunuchs, who had been appointed to attend her, and ordered him to go to Mordecai to learn what this was and why it was.
